DSCR Loan Reserve Requirements: How Many Months of PITIA You Actually Need in the Bank

A deal can clear DSCR at 1.05x, clear credit at 700, and still die at the closing table — because the file comes up short on reserves. Reserves are the liquid cash a borrower has to show in the bank after the down payment and closing costs are covered, and on a DSCR rental loan they are underwritten almost as carefully as the rent itself. Investors who budget for the down payment and skip budgeting for reserves are the ones who get an “approved subject to conditions” email three days before their rate lock expires.

Here is how the reserve number is actually built, why it climbs well past six months on some files, and what to do when the cash you have doesn’t match the cash the file needs.

What counts as a reserve, and what doesn’t

A reserve is liquid: checking, savings, money market, or an investment account that can be converted to cash inside a few days. Retirement accounts (401(k), IRA) usually count at a discount — commonly 60–70% of the vested balance — because of early-withdrawal penalties. Gift funds are typically excluded from reserves even when they’re allowed toward a down payment, since reserves exist to prove the borrower can carry the property through a vacancy, not that someone handed them a check. Most DSCR programs also want the funds seasoned: sitting in the account, documented on two consecutive bank statements, before the file goes to underwriting. A $40,000 deposit that lands the week before closing raises more questions than it answers.

The baseline: six months of PITIA, and the arithmetic behind it

On a standard 1–4 unit rental at or under 75% LTV with a DSCR of 1.0 or better, the common reserve requirement is six months of PITIA — principal, interest, property taxes, insurance and HOA dues, the same number used to calculate the DSCR ratio itself.

Work it through on a real file: a $500,000 purchase at 75% LTV is a $375,000 loan. At an indicative 7.0% rate on an interest-only structure, that’s $2,187.50 a month in interest. Add $300 a month in property taxes and $150 a month in insurance, and PITIA lands at roughly $2,637.50. Six months of reserves on that file is about $15,825 — on top of the $125,000 down payment and closing costs. Borrowers who price out the down payment and stop there are routinely $15,000–$20,000 short of what the file actually needs to clear underwriting.

Why the number climbs: DSCR, leverage and unit count

Six months is the floor, not the number every file gets. Reserve requirements move with risk, and three things push them up:

*Indicative ranges; the actual figure is set at underwriting based on the borrower’s full credit and portfolio picture, and is never a guarantee.

Run the same arithmetic on a weaker-coverage file: a property that only supports a 0.80x DSCR at that same $375,000 loan amount is carrying more risk per dollar financed, so we want nine to twelve months, not six — roughly $23,700 to $31,600 on top of the down payment, instead of $15,825. On a 5+ unit or mixed-use deal, the loan size and the PITIA are both larger: an $800,000 loan at 7% interest-only runs about $4,667 a month in interest alone, plus taxes and insurance, for a PITIA near $5,367. Twelve months of that is roughly $64,400 sitting in the bank before we can clear the file to close.

The stacking rule for portfolio investors

Reserves aren’t calculated against the subject property alone once an investor owns other financed rentals. Most DSCR programs add reserves for each additional mortgaged investment property in the borrower’s portfolio — commonly two months of that property’s own PITIA per property, often capped once the count gets high. An investor closing their fourth rental isn’t just reserving against the new loan; they’re reserving against the three they already carry. This is the stacking math that catches experienced investors off guard more often than first-time buyers, because the first deal cleared easily and nobody re-ran the number before deal number four.

When this is the wrong call

If the reserve requirement on the file you want doesn’t match the cash you actually have, forcing the deal is the wrong move. A borrower with $40,000 liquid chasing a 5+ unit mixed-use purchase at 75% LTV and a sub-1.0 DSCR is looking at a down payment, closing costs, and a $60,000+ reserve requirement — the math doesn’t close, and padding the file with projected rent increases or unseasoned deposits just gets the loan declined later instead of now. The better move in that situation is to drop leverage (a lower LTV lowers both the loan amount and the PITIA it’s measured against), move the deal into the standard 1–4 unit DSCR program instead of the 5+ unit tier if the property qualifies, or hold the deal for a quarter while reserves season properly. A deal that’s six months away from being fundable is not the same as a deal that’s unfundable.

Closing the reserve gap without re-trading your own deal

The fastest fix is usually leverage, not income: a borrower short on reserves at 80% LTV often clears easily at 70%, because both the loan amount and the monthly PITIA drop together. Paying a point to buy down the rate has a similar effect — a lower monthly PITIA means fewer dollars per month of required reserves. Beyond that, documented retirement balances (counted at the usual partial discount), a co-borrower’s liquid accounts, or simply waiting two statement cycles for a deposit to season are all more reliable paths than trying to negotiate the reserve requirement down — that number is tied to the loan’s rate and prepayment structure on our current rates and terms page, and it moves with the file, not the other way around.

Reserves get underwritten the same way DSCR and credit do: against the actual numbers on the actual file, confirmed before closing, not assumed from a rough budget.
