Okay, one of my Master’s of Social Work (MSW) classmates was buying her first house here in Louisville, and she had everything lined up perfectly. Or so she thought. She got preapproved, found the perfect bungalow in the Highlands, made a competitive offer, and then the seller's agent asked for proof of funds within 24 hours. She panicked because she didn't even know what that meant. By the time she figured it out and got her documentation together three days later, another buyer with their paperwork ready had swooped in.
That story stuck with me because it happens more than you'd think. In my MSW program, we learned about how systems thinking applies to major life transitions, and buying a home is one of the most stressful systems people navigate. The thing is, proof of funds is actually pretty straightforward once you understand what it is and why sellers care about it so much.
Let me simplify this for you. A proof of funds letter is basically your financial institution saying, "Yes, this person actually has the money they claim to have." It's different from your mortgage preapproval, which says a lender is willing to loan you money. Think of it like this: the preapproval shows you can borrow, the POF shows you can pay. Sellers want both because it proves you're a serious buyer who can actually close the deal.
A proof of funds letter is an official document from your bank or financial institution that verifies you have specific liquid assets available right now. According to the Consumer Financial Protection Bureau's guidance on homebuying documentation, this verification helps establish buyer credibility in real estate transactions.
Here's the thing nobody tells you: not all POF letters are created equal. I've seen buyers get their letters rejected because they used a screenshot of their mobile banking app or printed an unofficial statement. That doesn't cut it. You need the real deal, on bank letterhead, with an actual signature.
Let me walk you through a real example. Let's say you're buying a $350,000 home with a conventional loan requiring 10% down:
Your POF letter needs to show at least $49,000 in accessible funds. Actually, I'd recommend showing a bit more, maybe $55,000, because sellers and their agents like seeing a cushion. It signals you're financially stable and won't have trouble closing.
This is where people get tripped up. You can't just point to any asset and call it proof of funds. The key word here is "liquid," meaning you can access the money quickly without penalties or complicated procedures.
What Counts:
What Doesn't Count:
According to Fannie Mae's Selling Guide on asset assessment, lenders verify liquid assets through specific documentation standards, and these same standards generally apply to seller expectations for POF letters.
I learned this the hard way through underwriting years ago. We had a buyer who tried to use their stock portfolio as proof of funds. The problem? The market was volatile that week, and by the time we'd have converted those stocks to cash, the value could've dropped $10,000. The seller said no thanks.
People confuse these two all the time. Let me break it down in the clearest way possible.
Mortgage Preapproval:
Think of preapproval as showing you can make the monthly payments, while POF shows you can get to the closing table in the first place. You need both.
At AmeriSave, we help buyers understand this distinction during the mortgage preapproval process. We make sure you know exactly how much cash you'll need at closing so you can get your POF documentation ready before you start house hunting. According to the Federal Housing Finance Agency's 2025 homebuyer survey, buyers who prepare complete documentation in advance close 12 days faster on average than those who gather paperwork reactively. It's all about being prepared.
Here's a scenario I see frequently: A buyer gets preapproved for $400,000 and starts looking at homes in that range. They find one they love at $395,000. Great, right? But then they realize they need about $50,000 in cash for the down payment and closing costs. Wait, let me clarify that. Actually, with closing costs it's closer to $55,000 when you factor in all the fees. If they don't have that much liquid, they can't get a POF letter, and suddenly that preapproval doesn't matter.
Not every transaction requires POF upfront, but you should expect to provide it in these situations:
Always Required:
Sometimes Required:
Rarely Required (But Good to Have):
I was just in class learning about how organizations create unnecessary barriers to services, and honestly, POF requirements can feel like that sometimes. But here's the reality: sellers aren't trying to make your life difficult. According to the National Association of REALTORS® 2025 Market Data, the median days on market has decreased significantly in many areas, and sellers use POF letters to quickly identify serious buyers who can close fast.
In Louisville right now, our market is competitive enough that I'm seeing POF requests on almost every offer. Sellers know that if one buyer can't produce the funds, they're losing precious time they could've spent with another buyer. It's just risk management.
I've reviewed hundreds of these through my years in underwriting and project management, and I can tell you exactly what makes a good POF letter versus one that'll get rejected.
Essential Elements:
What Can Hurt Your POF Letter:
Let me show you what this looks like in practice. Say you need $60,000 for your purchase:
Strong POF Letter Shows:
Weak POF Letter Shows:
That second example? I've seen deals fall apart over exactly that kind of documentation. Sellers get nervous when things don't look solid.
Okay, so here's the process, and honestly, it's simpler than most people think once you know what to do.
Don't just guess. Work with your lender or real estate agent to determine:
Let's work through a real calculation for a $280,000 home purchase:
Expense: Down Payment
Calculation: $280,000 x 0.10 = $28,000
Closing Costs (3%): $280,000 x 0.03 = $8,400
Earnest Money (2%): $280,000 x 0.02 = $5,600
Total Needed: $42,000
Recommended Cushion (15%): $42,000 x 0.15 = $6,300
Ideal POF Amount: $48,300
If you have money in more than one bank or account, think about moving it all into one or two accounts. Here's why: the more accounts you list, the more paperwork you need, and sellers will find it harder to understand your finances.
When my husband and I bought our house here in Louisville, we had money in four different accounts. I'm so glad we followed our agent's advice to combine. It made the whole thing cleaner.
You can either call your bank's customer service number or go to a branch in person. Tell them that you need an official letter of proof of funds for a real estate deal. The banker will probably ask:
Most banks can do this for free in 1 to 2 business days. Some may charge a small fee ($10–25) for faster service or for making more than one copy. The FDIC's consumer banking rules (as of October 27, 2025) say that banks must send account verification letters to customers who ask for them. However, they can set reasonable fees and timeframes for doing so.
If something is wrong, ask for a new copy right away. Don't try to get around mistakes.
As someone who has managed projects in both underwriting and tech development, I've seen these mistakes ruin deals that were otherwise good:
I can't tell you how many times I've seen buyers rush to get POF letters after they made an offer. Banks need time to get the paperwork ready. Before you start making offers, ask for your letter. Not after.
Your POF letter should show that you have enough money to cover all of your costs and then some. Sellers are worried that you won't be able to pay for unexpected costs that come up during closing if you're cutting it too close. According to Freddie Mac's Loan Prospector guidelines, lenders also check to see if borrowers have enough money left over after closing. Sellers often have the same worry.
Your $100,000 stock portfolio might look good, but it won't work as proof of funds (POF) if it's not liquid and your broker has promised to sell it. Stay with what is clearly available.
If you want to borrow your down payment from family or take out a personal loan, you'll need to show proof that it's a gift (if it's from family) or that you can afford the loan with that debt included. Don't try to hide money you borrowed in your POF.
POF letters only last for a certain amount of time, usually 30 to 60 days. If it takes longer than you thought to find a house, you'll need to ask for a new letter. Make a note to yourself.
Your POF letter has your account numbers and balance information. Give it only to people you can trust who are involved in the deal. People have stolen identities after sharing financial documents carelessly. The Federal Trade Commission's advice on keeping financial documents safe stresses that sensitive banking information should only be shared with verified recipients in legitimate transactions through encrypted channels.
If you get some of your down payment from a family member, you'll need a POF letter showing how much money you have now and a gift letter from the person who gave you the money that says:
The HUD Handbook 4000.1 lists the exact requirements for gift fund documentation in FHA transactions. Conventional lenders have similar rules.
If you are taking money out of your 401(k) or IRA to use as a down payment, you will need to show proof of:
Keep in mind that it can take 7 to 10 business days for retirement withdrawals to go through, so plan ahead.
If you're selling another property to pay for your new one, your POF comes in two parts:
Unless your sale is completely finished and funded, many sellers won't accept this as proof of funds. If not, it's too risky.
If your money is in a foreign bank or currency, you will need:
We work with international buyers all the time at AmeriSave, and our preapproval process can help you figure out what documents you need.
The mortgage business is changing, and POF verification is changing with it. When we added some processes to AmeriSave's tech platform, we had to carefully plan how to update financial verification without compromising security.
Many lenders will now accept digital bank statements that you download directly from your bank's website, as long as they have the bank's digital signature or verification mark. This makes it take less time to get official letters.
With your permission, Automated Asset Verification services can now connect directly to your bank accounts and verify your information right away. According to information from the Mortgage Bankers Association's Technology Solutions Conference 2024, about 47% of lenders now use some form of automated asset verification. The Office of the Comptroller of the Currency's guidance on digital banking services has set security standards for these verification platforms. This means that your financial information will stay safe while you verify your assets online.
Verification based on blockchain is coming soon. Several fintech companies are testing systems that let your bank cryptographically check your assets without giving them any specific account information.
The textbook answer from my finance classes would say that this is all about efficiency. But in reality, it's about making things easier and less stressful for buyers. In a competitive market, it's a big deal if you can get instant asset verification instead of waiting days for your bank to send you a letter.
Proof of funds letters aren't hard to understand once you get the hang of them, but they're very important in today's real estate market. The most important thing is to be ready before you need them. This is what you need to do right now:
At AmeriSave, we tell our customers exactly what paperwork they need at each step of the process. When you get preapproved for a mortgage with us, we'll help you figure out not only how much you can borrow but also how much cash you need to have on hand. That planning makes a big difference when you're trying to get the house of your dreams.
What do you think is the biggest mistake? People only think about getting preapproved and forget about the money part. Don't be the buyer who finds the perfect house but can't show they have the money to close. Prepare your proof of funds documents ahead of time and keep them up to date. This way, you'll be ready to act quickly when the right property comes along.
Most sellers and lenders want POF letters that are dated between 30 and 60 days before you make your offer. The shorter the time frame, the better, because it shows how much money you have right now. You will need to ask your bank for a new letter if it takes you more than 30 days to find a home. The good news is that once your bank makes your first POF letter, it usually takes a lot less time to update it again, sometimes just a few hours. Even if your last letter is still technically within the acceptable timeframe, I always suggest asking for a new one before you make an offer. Some banks will automatically date your letter to the day you ask for it, while others might date it a few days earlier based on when they got the information. Ask your banker directly about how they date.
Sometimes, but don't count on it, is the short answer. If the market isn't as competitive or the sellers are more flexible, a recent bank statement might be fine as long as it clearly shows your account balance, account holder name, and bank information. Most sellers, on the other hand, prefer official POF letters because it's harder to fake them. You can change bank statements, edit screenshots, and online banking displays aren't always reliable. A signed letter on bank letterhead from an official source gives you more confidence. I've seen deals where sellers first said a bank statement was fine, but then another buyer made an offer with an official POF letter, and all of a sudden the first buyer had to provide one too. I always say to get the official letter. It doesn't cost much at most schools, and it makes you look like a serious, ready buyer.
This is where things start to get tricky. Stocks, bonds, mutual funds, and other types of investments are technically liquid, but they have two big problems when it comes to POF. First, their value changes, sometimes a lot, so the amount you have now may not be the same next week. Second, after you sell investments, you usually have to wait a few days before you can get the money. For stocks, this is usually 2–3 business days, according to the Securities and Exchange Commission's trading settlement guidance. Some sellers will take brokerage statements that show how much money you have in your investments, along with a letter from your company promising to sell and move the money by a certain date. But a lot of sellers don't want to accept this because it makes things less certain. I strongly suggest that you sell your investments and put the money into a regular bank account at least two weeks before making offers if you know you'll need to use the money.
Yes and no, depending on your market and your situation. You don't have to put as much money down for FHA and VA loans. You only need to put down 3.5% for an FHA loan, and for qualified veterans, VA loans often don't require any down payment at all. So, you don't need as much cash as you would with regular financing. But you still need to show that you have the money to pay for closing costs, which are usually between 2% and 5% of the purchase price. Even buyers who are using FHA or VA loans are being asked to show proof of funds (POF) letters to show that they are ready to buy. Some sellers worry that FHA or VA buyers might not be able to meet all of their financial obligations, but showing strong proof of funds can help with that. You could also send your Certificate of Eligibility along with your POF letter to show that you are fully qualified if you are using a VA loan. That full set of documents shows that you're a serious buyer who is ready to move forward.
If your parents or another family member are giving you money for your down payment, you'll need more than just a POF letter. The donor will need to show proof of funds to show they have the money, as well as a gift letter that says the money is a gift and they don't expect to get it back. The letter needs to say how much money the donor is giving you, how they know you, that it's a gift and not a loan, and have both you and the donor sign it. Lenders are very picky about gift money because they want to make sure you're not taking on debt that you don't know about. They'll also want to see proof that the money moved from the donor's account to yours. You can't just put someone else's money in an account with their name on it and call it your POF. The money has to be in your name or in a joint account where you are listed as an owner. Fannie Mae's gift fund requirements say that certain documentation standards must be met.
I really care about this. Your proof of funds letter has private information like your account numbers, bank name, balances, and personal information that can be used to identify you. The first rule is that you should only give your POF letter to people who have been verified and really need it for your transaction. That usually means your mortgage lender, your real estate agent, the seller's agent, and maybe even the seller themselves. Check the identity and legitimacy of anyone you send it to first. If you want to send it by email, don't use regular email. Instead, use encrypted email services or secure document sharing sites. A lot of real estate agents now use secure transaction management platforms where you can upload documents that are encrypted and only certain people can see them. You might want to ask your bank if they can hide part of your account number and only show the last four digits. Make a list of everyone you've given your POF letter to. Don't ever text or message your POF letter through regular SMS or social media. After you buy something, safely destroy any copies that have full account numbers on them and keep just one safe copy for your records.
If you don't have enough cash on hand, you have a few choices. First, think again about whether the homes you're looking at are in your price range. If you need $50,000 in cash for a $350,000 home but only have $35,000, you might want to look at homes in the $250,000 range instead, where your money would be enough. Second, check out loan programs that don't require a big down payment. Some conventional loans only require 3% down for first-time buyers, while FHA loans only require 3.5% down. If you qualify, VA or USDA loans might not require any down payment at all. Third, look into programs in your area that can help with your down payment. The National Council of State Housing Agencies DPA database says that there are more than 2,000 programs in the United States. Fourth, think about asking family members if they would give you money for gifts. Fifth, wait a few more months and save up a lot. You should never try to fake your proof of funds. That is mortgage fraud, and it can have serious legal consequences.
There is a big difference. If you're buying with cash and no mortgage, your POF needs to show that you have enough cash on hand to cover the full purchase price plus closing costs. You'd need to show at least $408,000 in liquid assets for a $400,000 home with closing costs of $8,000. I'd suggest showing more like $425,000 to be safe. Sellers love cash buyers because there are no financing contingencies, no need for an appraisal that could kill the deal, and closing can happen much faster. The POF letter is the most important part of your offer. If you're getting a loan, your POF only needs to show that you have enough money to cover your down payment, closing costs, and any reserves your lender needs. If you were buying a $400,000 home with a conventional loan and putting 20% down, you would need to show about $100,000 total. If you were paying cash, you would need to show more than $400,000. In addition to the POF letter, buyers who are getting a loan also need their mortgage preapproval letter.
Yes, and in fact, online banks usually handle POF letter requests faster than regular banks because their whole system is set up for digital paperwork. Most of the time, banks like Ally, Marcus by Goldman Sachs, Capital One 360, Discover Bank, and others can send you official POF letters in 24 to 48 hours. Usually, you can do this by calling their customer service number or sending a secure message through your online banking portal. An online bank's POF letter will have everything you need, like official letterhead, your account information, current balances, and a signature from someone who is allowed to sign. One thing to think about is that some sellers or their agents may not be as familiar with online banks and may be worried at first. These days, when online banking is common, this is not likely to happen, but if it does, you can tell them that online banks are FDIC insured and follow the same rules as regular banks. As someone who has managed digital processes at AmeriSave, I can say that online banks are often more reliable and faster for making documents than many traditional banks.
