An underwriter will ask you to explain any deposit that does not fit the rest of your account activity, if that account is the one paying your down payment, closing costs, or reserves. There is no dollar figure that triggers the request. The test is whether the deposit is consistent with your own monthly deposit pattern, and the program's hard line is short: unverified funds are not acceptable.
That catches people because it runs backward from how borrowers think about money. You know where every dollar came from. The file does not. It knows only what two months of statements show, and a wire landing in a checking account that normally receives a fraction of that amount is, to an underwriter, an unexplained event that has to be closed before the loan clears conditions.
This page covers what makes a deposit large enough to source on a 1-4 unit investor (DSCR) file, what documentation actually satisfies the request, which funds are ineligible no matter how well you document them, and how to structure an account before you go under contract so the question never comes up.
What makes a deposit "large"
The program does not define large as a dollar amount or as a percentage of the purchase price. It defines it relationally.
Two things follow from that wording, and both matter more than a threshold would.
First, "inconsistent with monthly deposit activity" is a comparison against your account, not against a table. A deposit that dwarfs a month of normal rent collections is inconsistent. The identical amount in an account that routinely cycles many times that is unremarkable. Two borrowers with the same deposit can get different treatment, and neither is being handled inconsistently — the standard is doing exactly what it says.
Second, a newly opened account is its own trigger. If you moved money into a brand-new account to keep the closing funds separate and tidy, you have created the condition the guideline names explicitly. There is no deposit history to compare against, so every dollar in it is a large deposit by default. Tidiness reads as opacity here. Leave the money where it has been sitting.
The guideline is silent on a numeric floor, and it is also silent on a seasoning period after which a deposit stops being reviewable. Do not assume there is a 60-day rule that ages a deposit out of scope. What the guideline actually gives you is a documentation window, which is a different thing.
The documentation window: two months, 60 days of activity
Purchase funds have to be documented with the two most recent months of bank statements, or a Verification of Deposit form (FNMA 1006) completed by the depository institution. Separately, the asset verification must provide sixty days of account activity and include all items normally indicated on bank statements.
"All items normally indicated" is the part people underestimate. A one-page summary screenshot from a banking app, a balance printout, or a transaction export without the bank's header does not satisfy this. The file needs the actual statements, all pages, including the pages that are nothing but the fine print.
The two-month window also sets the shape of the risk. A deposit that landed 90 days ago will not appear in the statements you provide, so nobody asks about it. A deposit that lands the week you go under contract is guaranteed to appear. The practical consequence: the worst possible time to move money is the moment you decide to buy something.
What actually satisfies a sourcing request
The request is not satisfied by an explanation. It is satisfied by evidence, and the evidence has to tie to the exact amount and date shown on the statement.
The guideline names several acceptable sources and attaches conditions to each. Sales proceeds, commissions from a sale, and funds received from collateralized loans may be acceptable subject to receipt of appropriate evidence. Proceeds of a loan fully secured by real estate the borrower owns, other than the subject property, are acceptable. Gift funds are acceptable when they meet the program's gift fund requirements, which are their own subject — see [can you use gift funds for a DSCR loan](/blog/can-you-use-gift-funds-for-a-dscr-loan) for the donor rules and the limit.
| Deposit | What the file needs |
|---|---|
| Transfer from another account you own | Two months of statements for the sending account, showing the matching withdrawal |
| Proceeds from a sale of real estate | Closing statement or settlement statement for that sale, tying to the deposit amount |
| Proceeds of a loan secured by other real estate you own | Evidence of the loan and that it is fully secured by real estate other than the subject property |
| Commission from a sale | Evidence supporting the payment; underwriter determines whether the documentation is adequate |
| Earnest money already paid | Cancelled check or bank statement showing the funds held in escrow per the purchase and sale agreement |
| Gift from a close relative | Signed gift letter and verification of the donor's funds, per the gift fund requirements |
| Funds converted from digital currency | Documentation showing funds coming from a digital currency account owned by the borrower or guarantor, converted to U.S. currency and deposited into an eligible account |
| Foreign funds | Documented evidence of the foreign asset exchanged into U.S. dollars and held at a U.S. financial institution, verified in U.S. dollars before closing |
One structural rule sits underneath all of it: eligible assets must be held in a U.S. account. Money sitting offshore does not qualify as an eligible asset in place. It has to be exchanged into U.S. dollars, moved into a U.S. financial institution, and verified in dollars prior to loan closing — and it is permitted only if the source of the funds does not originate from a country on the prohibited, discouraged, or high-risk country list.
Worth naming plainly: the guideline assigns to the underwriter the judgment of whether the documentation you provided is sufficient. That is why a vague explanation loses and a document tying to the amount and date wins. You are not arguing a policy question; you are closing a gap in a paper trail.
Funds that are ineligible no matter how well you document them
This is the category that costs people deals, because the instinct when a sourcing request arrives is to explain harder. Some sources cannot be explained into eligibility. If the money came from one of these, the answer is to replace the funds, not to document them better.
| Ineligible source | Note |
|---|---|
| Cash-on-hand | Not permitted |
| Down payment assistance programs | Not permitted |
| Unsecured loans or cash advances | Not permitted, including cash advances on revolving credit cards or lines of credit |
| Personal unsecured loans | Listed separately as ineligible |
| Funds or cash that are not vested and/or seasoned | Where the source cannot be verified |
| Non-vested or restricted stock accounts | Not permitted; non-vested stock options and non-vested restricted stock are named separately |
| Stock held in an unlisted corporation | Ineligible |
| Gift of equity | Not permitted |
| Interested party contributions | Includes the seller, builder/developer, real estate agent, broker, or any affiliate who may benefit from the sale, or from the sale at the highest possible price |
| Seller, developer, or broker credits of any kind | Including advanced rent payments for a seller lease-back |
| Rent credits and sweat equity | Sweat equity means labor and materials used to improve the property |
| A loan from the borrower's own business | Ineligible unless placed on full stand-by (principal and interest) for the term of the loan and the source of funds can be verified |
| SBA Payroll Protection Plan (PPP) funds | Or any other similar COVID-19-related program |
| Funds that cannot be withdrawn | Except on the account owner's retirement, employment termination, or death |
Two of these deserve extra attention because they look harmless.
A cash advance is not a bridge. Borrowers short on closing funds sometimes pull a line of credit or take a card advance intending to repay it within days. That deposit is ineligible funds, and it does not become eligible by being repaid. Undisclosed borrowed funds are the specific thing sourcing exists to catch.
Money from your own business is not automatically your money. A loan from the borrower's business is ineligible unless placed on full stand-by for the loan term with principal and interest suspended and the source verified. A distribution or owner draw is a different transaction, but the file cannot tell which it is looking at unless you show it.
Money that is yours but does not look like it
Three situations come up constantly on investor files and all three are sourcing questions wearing different clothes.
Funds in a business account that is not in the borrowing entity's name. These can be used for down payment, closing costs, and reserves, but only with additional requirements met: the natural borrower or guarantor must own 25% or more of the entity holding the account, and must either be named on the account or provide proof of access to 100% of the funds from the other members. The underlying question is the same one being asked of every deposit — are these funds actually yours and actually available.
Digital currency. Not permitted as an asset in place. It is eligible only once converted to U.S. currency and deposited into an eligible asset account, with documentation showing the funds came from a digital currency account owned by the borrower or guarantor. Plan for the conversion to happen early enough that the resulting deposit can be paired with its exchange records.
A 1031 exchange. Requires the HUD-1 or Closing Disclosure for both properties and the exchange agreement. Reverse 1031 exchanges are not allowed under this program.
One place the guideline contradicts itself
It is worth being straight about this rather than papering over it, because it will affect a real file.
In the section describing acceptable down payment sources, the guideline says that sales proceeds, the sale of personal property, commissions from a sale, and funds received from collateralized loans may be acceptable subject to receipt of appropriate evidence. In the ineligible assets list, the same document lists "proceeds from the sale of non-real estate assets" as ineligible.
Those two passages point in opposite directions on the same fact pattern: you sold a vehicle, a piece of equipment, or a collection, and the proceeds are in your account. One passage says it may be acceptable with evidence. The other says it is ineligible.
Do not build a closing around the permissive reading. If proceeds from selling personal property are part of your down payment, raise it before you are under contract and get the file's treatment settled in writing, so you are not resolving a guideline conflict three days before funding with no time to substitute funds.
Sourcing does not stop at the down payment
The verification applies to down payment, closing costs, and reserves alike, and reserves have their own arithmetic that a mis-sourced deposit can break.
Reserves are measured in months of PITIA on the subject property: three months when DSCR is at or above 1.00, six months when DSCR is below 1.00, with an additional six months required for short-term rentals. Funds used for down payment and closing costs cannot also be counted as reserves. Liquid assets required for post-closing reserves are evidenced and verified prior to funding, and eligible assets across all borrowers and guarantors may be combined — but they should be verified at approximately the same time to prevent double-counting.
That last clause surprises people. If reserves are spread across accounts held by different guarantors and statements are pulled weeks apart, the same money can appear twice, and the fix is re-verifying everything on a common date.
One eligibility note tied to score: cash-out proceeds may be used for reserves if FICO is above 700. The program's minimum FICO is 660 for all guarantors, so there is a band of borrowers who qualify for the loan but cannot use their own cash-out proceeds to satisfy reserves.
Why a commercial bank statement file treats this differently
If you also have a small balance commercial file in process, you will notice the same phrase — large deposits — being used to ask a different question, and it is worth knowing why so you do not answer the wrong one.
On the commercial bank statement program, deposits are the income calculation. Twelve months of business bank statements are analyzed and averaged to determine monthly income, so when a large or atypical deposit gets sourced there, the question is whether the deposit is business revenue that belongs in the income figure, or something else that has to come out of it. The program even directs that consideration be given to the nature of the borrower's business and whether the deposit activity is reasonable and consistent with the business's operations, historical trends, and industry norms — an income-quality test.
On this investor program, deposits are not income. Qualification runs off the property's debt service coverage. So the sourcing question narrows to whether the funds are the borrower's own and legitimately available to close, with no undisclosed borrowing behind them. Same words, different burden. An explanation that would satisfy a commercial underwriter looking at revenue quality can leave an investor file's sourcing condition wide open.
How to prepare an account so the question never arises
None of this requires special handling. It requires deciding two months earlier than feels necessary.
Pick the account now and stop touching it. Choose one existing account with real history that will hold the down payment, closing costs, and reserve funds. Do not open a new one for the transaction.
Move everything before you shop. Any consolidation, gift, retirement distribution, digital currency conversion, or sale proceeds should land before the two-month window that gets pulled. Once under contract, treat the account as frozen except for ordinary activity.
Keep the paperwork with the deposit. For each non-routine deposit, save what proves it — settlement statement, sale contract, exchange confirmation, the sending account's statement — in one place. Assembling records after the request arrives is where deals slip.
Do not use funds from the ineligible list, even temporarily. A card advance repaid the following week is still a deposit on a statement.
Disclose the accounts you would rather not. The guideline asks borrowers and guarantors to disclose all liquid assets beyond the minimum requirement. A file that volunteers a second account is stronger than one where the underwriter finds it inside a transfer.
What this page does not do
This page explains how deposit sourcing is evaluated on The Fiirm's 1-4 unit investor program under DSCR V28. It is not an approval, not a quote, and not a commitment to lend. Nothing here prices a loan or confirms that a specific deposit will be accepted; the guideline assigns that determination to the underwriter reviewing your actual file.
It does not cover the gift fund rules in detail, or how retirement assets are discounted toward reserves — both are separate pages. It does not address the DSCR calculation itself, lease requirements, LTV limits, property eligibility, or the entity and guaranty structure.
The guideline is silent on a dollar threshold for what counts as a large deposit, and silent on any seasoning period that would remove a deposit from review. Where it is silent, no figure has been supplied here. It is also internally inconsistent on proceeds from the sale of non-real-estate personal property, and that conflict is presented above rather than resolved.
Tax treatment of a 1031 exchange, the legal structure of an entity or a stand-by agreement, and anything touching state law belong with your attorney or accountant, not with a lender's guideline summary.
