Down Payment Sourcing in Austin: How Lenders Trace Your Money
The median Austin-area home sold for $413,499 in the September 4, 2026 Team Price market update. Five percent down on that price is about $20,675, and most buyers spend months building that balance. Then the loan file opens, and underwriting asks a question nobody prepared them for: where exactly did this money come from? Having the cash is step one. Proving the cash is yours, and that it arrived from a source the loan program allows, is a separate step that has delayed more Austin closings than low credit scores have.
The rules behind that question are called sourcing and seasoning, and they are written into the Fannie Mae Selling Guide and the FHA handbook. They are not a judgment call your loan officer makes about you. Learn what they ask for and you can gather the paperwork on your schedule rather than three days before closing.
Key points:
- Lenders typically review the most recent two months of statements on every account you use for closing funds.
- On a conventional loan, a large deposit is a single deposit that exceeds 50 percent of your total monthly qualifying income (Fannie Mae B3-4.2-02). FHA uses 50 percent of monthly effective income.
- Money that has been sitting in your account for the full look-back period is seasoned and usually needs no explanation.
- Selling a car, converting crypto, borrowing from a 401(k), and pulling from a business account are all allowed, and each carries its own document list.
- FHA requires an earnest money deposit above 1 percent of the sales price to be verified and sourced.
- Undocumented cash deposits are one of the most common reasons a verified down payment gets reduced in underwriting.
What do sourcing and seasoning mean on a mortgage file?
Sourcing means proving where a specific dollar amount came from. Seasoning means how long that money has been sitting in your account. A deposit that has been in your checking account across both statements the lender reviews is seasoned, and underwriting generally accepts it without further questions. A deposit that landed last week is unseasoned, and if it is large enough, you will be asked to document its origin before the file clears to close.
The reason behind the rule is straightforward. Loan programs require that your down payment be your own money or a permitted gift, and not an undisclosed loan from a friend, an employer, or a seller. An undisclosed loan changes your debt load and your risk profile after closing, so lenders verify it up front rather than discovering it later.
Seasoning is why the calendar matters more than most buyers expect. If you move money from a brokerage account into checking today, that transfer will be visible for the next two months of statements, so plan the timing around your loan application, not around your closing date.
What counts as a large deposit on your bank statements?
On a conventional loan, Fannie Mae defines a large deposit as a single deposit that exceeds 50 percent of your total monthly qualifying income. If you qualify on $8,500 a month, any one deposit above $4,250 gets flagged. FHA applies the same 50 percent test against your total monthly effective income. Deposits below the threshold, and regular payroll deposits of any size, are not treated as large deposits.
Here is the part that saves buyers time. A flagged deposit is a request for paperwork, and it clears as soon as you supply it. For a purchase, Fannie Mae’s rule is that if funds from a large deposit are needed to complete the transaction, the lender must document that those funds came from an acceptable source. Document it and the money counts in full. Leave it undocumented and the lender reduces your verified funds by that amount, which can put the whole file back on the drawing board.
Two months is the standard window because bank statements covering the most recent two months are what lenders typically evaluate. Practically, that means every deposit you make between roughly 60 days before application and closing day is subject to review.
Which down payment sources need extra paperwork?
Every source below is permitted. What separates them is how much lead time each one needs, and lead time is the part buyers control.
| Source of funds | What underwriting asks for | Typical lead time |
|---|---|---|
| Payroll and ordinary savings | Two months of statements; deposits match your pay | None |
| Sale of a car or other personal property | Proof you owned it, a bill of sale, and evidence the proceeds were received and deposited | 1 to 2 weeks |
| Cryptocurrency | Evidence it was exchanged into U.S. dollars and held at a U.S. or state regulated institution, verified before closing | 30 days or more |
| Business account funds | Your name on the account, plus a business cash flow analysis if self-employment income qualifies you | 1 to 2 weeks |
| 401(k) loan | The loan instrument showing the account as collateral, plus proof the funds landed in your account | 2 to 3 weeks |
| Gift from a family member | Signed gift letter and a documented transfer from donor to borrower | 1 to 2 weeks |
| Cash kept at home | FHA: a written explanation of how it accumulated, then a deposit into a financial institution. Conventional: usually not usable | 60 days or more |
Sale of personal property. FHA lets you count the lesser of the estimated value or the actual sales price, and asks for a value estimate, a copy of the bill of sale, and evidence you received and deposited the proceeds. A Venmo payment from a stranger with no bill of sale behind it does not clear that bar.
Cryptocurrency. Fannie Mae guideline B3-4.1-04 accepts virtual currency that has been exchanged into U.S. dollars, with documented evidence of the exchange and the funds held in a U.S. or state regulated financial institution, verified before closing. One detail catches Austin buyers repeatedly: virtual currency cannot be used for the earnest money deposit on the home you are buying. Convert first, deposit into your bank, then write the earnest money check.
Business funds. If you own a business, its account can fund your down payment when you are listed as an owner and the account is verified. When your self-employment income is what qualifies you, the lender also performs a business cash flow analysis to confirm that pulling the money out will not damage the business. Expect to provide several months of business statements or a current balance sheet for that review.
401(k) loans. Borrowing against your own retirement account is common and it has a helpful quirk. Under Fannie Mae B3-6-05, updated August 5, 2026, the payment on a loan secured by a financial asset does not have to count in your debt-to-income ratio, as long as the lender has the loan instrument showing that asset as collateral. If you also need those funds for reserves, the account balance gets reduced by the loan proceeds. Our post on reserves and cash after closing covers how that math works.
Gift money. Gifts from family are allowed on conventional, FHA, and VA loans with a signed gift letter and a documented transfer. The documentation trips people up often enough that we wrote a separate piece on the mistakes that stall gift-funded loans.
Can you use cash you saved at home to buy a house in Austin?
On an FHA loan, yes, with conditions. The lender must obtain your explanation of how the cash accumulated and over what period, then assess whether that story is reasonable against your income, your spending, your documented expenses, and your history of using financial institutions. The cash then has to be deposited into a financial institution or held by the escrow or title company. On a conventional loan, cash on hand is generally not an acceptable source.
So the practical answer for most Austin buyers is to stop keeping closing funds in a safe at home. If you are holding cash you intend to use, deposit it and let it season through two full statement cycles before you apply. Money deposited more than two months before your file is reviewed is not part of the conversation.
A 60-day checklist for keeping your down payment clean
Work this list backward from the day you expect to apply, not from your closing date.
- Consolidate early. Move funds from savings, brokerage, or a second bank into the one account you will use for closing, and do it before the two-month window opens. Fewer accounts means fewer statements to explain.
- Stop depositing cash. Sell items for a traceable payment, keep the receipt, and skip cash entirely once you are within 60 days of applying.
- Keep every receipt for anything you sell. Bill of sale, the buyer’s payment record, and the deposit into your account. Gather these when the sale happens, not when underwriting asks.
- Convert crypto well ahead of time. Exchange to dollars, move to your regulated bank account, and save the exchange records.
- Write the explanation letters as you go. A two-sentence letter of explanation naming what the deposit was and where it came from, written the week it happened, beats reconstructing it from memory two months later.
- Leave the money alone once you apply. Large transfers between your own accounts during underwriting create fresh deposits that need fresh documentation, even though nothing changed about your net worth.
All of this work is about how smoothly the money you already have clears underwriting. If you are still deciding on your number, our breakdown of what 3, 5, 10, and 20 percent down actually cost pairs with this one, and the Austin housing market page tracks the price data those percentages apply to.
Frequently Asked Questions
How far back do lenders look at my bank statements?
Lenders typically review the most recent two months of statements for every account you plan to use for the down payment and closing costs. Anything deposited before that window is seasoned and generally needs no explanation. Anything inside it may be questioned if it is large enough.
What is considered a large deposit on a mortgage application?
On a conventional loan, Fannie Mae defines it as a single deposit that exceeds 50 percent of your total monthly qualifying income. On $8,500 of monthly income, that is any deposit above $4,250. FHA applies the same 50 percent test to your monthly effective income.
Do I have to explain every deposit in my account?
No. Regular payroll deposits and anything under the large-deposit threshold usually pass without comment. Underwriting focuses on deposits that are unusually large relative to your income and on any deposit needed to complete the purchase.
Can I sell my car to cover the down payment?
Yes. Document that you owned the vehicle, provide a bill of sale, and show the proceeds being received and deposited. FHA counts the lesser of the estimated value or the actual sales price. Take a traceable payment rather than cash so the trail stays clean.
Can I use money from my 401(k) for a down payment?
Yes, through a withdrawal or a loan against the account. Under Fannie Mae B3-6-05, a loan secured by your own retirement account does not have to be counted in your debt-to-income ratio when the lender has the loan instrument showing the account as collateral. Check the tax consequences of a withdrawal with your CPA first.
Will a cash deposit stop me from closing?
It can reduce the funds the lender will count. On a conventional loan, cash on hand is generally not an acceptable source, and an undocumented large deposit gets subtracted from your verified assets. FHA allows cash on hand with a written explanation of how it accumulated and a deposit into a financial institution.
Every file at Mortgage Austin gets an asset review early, while there is still time to fix a paper trail instead of scrambling at the closing table. If you are eight weeks out from making an offer and want to know which of your accounts will raise questions, schedule a discovery call and we will walk through your options together. No pressure, no commitment, just clarity about what underwriting will ask you for.
