Bank Statement Loan Reserves By Property Type And Loan Size — The Quick Read: Reserves are the liquid cash a borrower must show left over after closing, measured in months of the full housing payment. Across a wholesale bank-statement network, that figure typically runs 3 months to $500,000, 6 months to $1,500,000, and 9 months above that — plus roughly 2 extra months for each additional financed property, capped near 12 months. First-time investors often get held to the 12-month figure regardless of loan size. Property type matters less than loan size and program design, but it does shift the math at the edges.
Most explanations of reserves treat them like an afterthought — a line item tucked below credit score and down payment. That’s backwards. On a bank statement file, reserves are frequently the thing that decides whether the deal closes at all. A borrower can have strong deposits, a clean 700 credit score, and 25% down — and still get stuck if the bank account is thin after closing costs clear. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
This piece walks through how reserves actually get sized on bank statement and portfolio non-QM loans: what counts as a reserve, how the number scales with loan amount, how property type nudges it, and where the general rule breaks down.
Key Terms Defined
PITIA is the full monthly housing payment: principal, interest, taxes, insurance, and any HOA dues. Reserves are always measured against this number, not just principal and interest.
Reserves are liquid or near-liquid assets a borrower must have left over after the down payment and closing costs are paid — proof there’s a cushion if rent stops or a tenant moves out.
Seasoning means the funds have sat in the borrower’s account for a set period (commonly around 60 days) so the lender can confirm the money isn’t a last-minute loan or gift.
Expense ratio is the percentage a lender subtracts from gross bank deposits to estimate real business overhead before calculating qualifying income — it’s how bank statement lenders convert deposits into an income figure.
How Reserves Actually Get Sized
The number of months required tracks loan size first, property count second, and borrower history third — property type itself rarely moves the number much on its own.
Across the wholesale programs Lendmire places files with, the reserve ladder on a portfolio bank-statement loan typically runs like this: 3 months of PITIA up to a $500,000 loan amount, 6 months up to $1,500,000, and 9 months above that. Add roughly 2 months for every additional financed property the borrower carries, up to a practical ceiling around 12 months. A first-time investor — someone financing a rental for the first time — often gets held to that 12-month figure no matter how small the loan.
That’s a meaningfully different structure than what shows up in conventional lending, where Fannie Mae’s own guide layers reserve requirements as a percentage of the aggregate unpaid balance across a borrower’s other financed properties — 2% for one to four properties, climbing to 4% and 6% as the count rises (Fannie Mae Selling Guide B3-4.1-01). Bank statement and portfolio programs generally skip that percentage-of-balance math and just stack flat months per property instead. Simpler to calculate, but it adds up just as fast once a borrower owns four or five rentals.
Documentation matters here too. Reserves need to sit in an account the lender can actually verify — checking, savings, or a retirement account, discounted for taxes and early-withdrawal risk. Funds that just landed in the account, or that came from a source the lender can’t trace, generally don’t count until they’ve seasoned.
Does Property Type Change the Reserve Number?
Directly, not much — property type shapes the loan size and the LTV a borrower qualifies for, and that indirectly moves reserves through the loan-size ladder.
A condo, a single-family rental, and a small multi-unit property don’t carry different reserve schedules by themselves on the programs in Lendmire’s network. What changes is the leverage ceiling attached to each property type. That changes the loan amount, which in turn changes where the file lands on the reserve ladder.
Warrantable condos can go to 80% LTV on a primary residence in the applicable size band, non-warrantable condos typically run 5 points lower, and condotels are capped further — commonly 75% on a purchase and lower on cash-out, with the bank portfolio program running its own tighter condotel ceiling. Two-to-four unit properties can reach up to 85% depending on size and occupancy. None of that changes the months of reserves required — it changes the loan amount, which is what actually drives the reserve tier.
Second homes are limited to single-unit properties on these programs. This keeps their reserve exposure simpler than a multi-unit rental portfolio. Rural properties are capped at 80% LTV on ten acres or less within the standard loan-size range. Leverage steps down at higher loan amounts, and rural properties are excluded entirely above the $3,000,000 loan-size mark. This is another example of property characteristics working through leverage limits rather than adjusting the reserve count directly. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
The Loan-Size Ladder — Where the Real Scaling Happens
Loan size is the dominant variable in reserve sizing on a bank statement file, and the effect compounds as amounts climb past the million-dollar marks.
Below $500,000, 3 months of PITIA is the typical floor across the wholesale network. Between $500,000 and $1,500,000, that steps up to 6 months. Above $1,500,000, plan on 9 months — and that’s before stacking in extra months for other financed properties or a first-time-investor adjustment.
At the high end, the math shifts entirely. Files above roughly $6,000,000 move onto a separate bank portfolio program built specifically for twelve-month bank-statement documentation, with its own leverage ladder rather than a flat percentage: 65% LTV up to $5,000,000, stepping to 60% up to $10,000,000, and 55% up to $30,000,000, with interest-only capped at 60% or the band’s ceiling, whichever is lower. That bank program’s ladder actually begins above $4,000,000 and overlaps the portfolio program up to $6,000,000 — above $6,000,000, the bank program stands alone. Every file above $4,000,000 gets reviewed case by case before it’s even submitted, and that includes reserve expectations — there’s no flat number to quote at that size, only a range subject to full underwriting. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Leverage itself steps down as loan size rises, even before hitting the case-by-case zone. On a primary residence, purchases can reach 90% up to $1,000,000, stepping to 85% up to $2,000,000, 80% up to $3,000,000, and 75% at the top credit tier up to $4,000,000 — all subject to underwriting and typically requiring higher credit at each step up. Investment properties and second homes generally run about five points lower than the primary-residence figures at comparable sizes. Investors chasing maximum leverage on a rental should expect that gap, and should expect it to widen the reserve conversation, not shrink it — lower leverage on an investment property partly offsets the fact that rental cash flow is inherently less stable than an owner’s paycheck.
What Actually Counts as a Reserve
Not every dollar in a bank account qualifies, and the discount schedule surprises a lot of first-time bank-statement borrowers.
Checking and savings balances generally count in full once seasoned. Retirement accounts typically count at 70%, rising to 80% for borrowers 59.5 or older, reflecting tax exposure on early withdrawal. Business funds, gift funds, funds from a trust other than a revocable living trust, unvested stock, and cryptocurrency generally don’t count as reserves at all on these programs — a distinction that catches a lot of self-employed borrowers off guard, since business accounts often hold the bulk of their liquidity.
Sometimes a borrower’s income comes from an asset-based path instead of bank deposits. In that case, reserves interact differently. One option is an asset-allowance qualification path, which divides liquid assets by 36, 60, or 84 months depending on the file. This path is available on primary and second homes up to 80% LTV. Another option is an assets-only path. This requires enough liquidity to cover the loan amount, closing costs, and 60 months of any net loss on other residential property — with no debt-to-income ratio calculated at all. Above the super-jumbo threshold, cash-out proceeds cannot be used to satisfy reserve requirements. The funds have to already be sitting in the account, separate from anything pulled at closing. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Where the General Rule Breaks: Named Edge Cases
Cash-out above 60% LTV. On the portfolio bank-statement program, cash-out proceeds are unlimited at or below 60% LTV, but a $1,500,000 cash-in-hand cap applies above that threshold. Reserves are still calculated on the resulting loan size — a large cash-out refinance can push a file into the 9-month tier even if the original loan was smaller. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Super-jumbo overlays. Above $3,500,000 on a primary residence, or $3,000,000 on a second home or investment property, a stricter overlay kicks in: a 700 credit floor, 48-month seasoning on any credit event, and — critically — cash-out proceeds cannot satisfy reserves at all. Reserves have to be demonstrated from funds entirely separate from the transaction itself.
Multiple financed properties. Every additional property a borrower already carries financing on adds roughly 2 months to the reserve requirement, up to the 12-month ceiling. An investor with three or four rentals already on the books should expect to sit near that ceiling on the next acquisition, even if the new property itself is modest in size.
First-time investors. Borrowers financing an investment property for the first time are typically held to 12 months of reserves regardless of loan size — the loan-size ladder essentially gets overridden by inexperience as a risk factor.
Interest-only structuring. On the portfolio program, interest-only is available up to 85% LTV with a 700 credit floor, structured as a 40-year term with a 10-year interest-only period. On the bank program, interest-only tops out at 60% LTV using 5- and 7-year fixed-period adjustables — a 10-year fixed-period adjustable on that program is fully amortizing, not interest-only. Interest-only structuring itself doesn’t change the reserve months required, but it does change the monthly obligation the reserve months are measured against.

Rental Income Documentation and Reserve Context
When a lender reviews rental income on a small residential income property, appraisers commonly turn to Fannie Mae’s rent comparison forms as a documentation reference point. This happens even on files that fall outside agency guidelines. Form 1007 covers one-unit comparable rent schedules. Form 1025 covers the small residential income property operating statement (Fannie Mae Form 1025; Blueprint’s Form 1007 explainer). These forms don’t set reserve policy. They establish market rent instead. Still, lenders often pull them into a non-QM file for consistency, since they’re a familiar reference point.
A Practitioner’s Read on Where Files Actually Stall
Across the wholesale network Lendmire places bank-statement files through, the deal that stalls almost never stalls on income — it stalls on cash left over. A borrower with strong deposits and a 25% down payment can look approvable on paper and still come up short once closing costs and a 6- or 9-month reserve requirement are subtracted from the account. The fix is usually structural — a smaller loan amount, a slightly higher down payment, or shifting the property to a lower-leverage tier — not a credit or income fix. Reserves respond to restructuring faster than almost anything else on the file.
FAQ
Do bank statement loan reserves change if the property is a short-term rental instead of a long-term lease? The reserve months themselves are typically tied to loan size and property count, not lease type. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income when planning their reserve cushion.
Can I use retirement account funds to cover my reserve requirement?
Yes, generally at a discount — retirement accounts typically count at 70% of value, rising to 80% for borrowers 59.5 or older, to account for tax exposure on an early withdrawal, subject to lender guidelines.
If I already own two rental properties, does that push my reserve requirement up on a new purchase? Typically yes. Each additional financed property generally adds roughly 2 months of reserves on top of the loan-size baseline, up to a practical ceiling near 12 months, subject to program guidelines.
Do gift funds count toward reserves the same way they can toward a down payment?
No. Gift funds are generally excluded from reserve calculations on these programs even where they’re accepted for down payment or closing costs — lenders want seasoned, borrower-sourced liquidity for reserves specifically.
Is there a difference in reserves between a primary residence and an investment property at the same loan amount? The reserve months generally follow the same loan-size ladder either way, but investment properties carry lower maximum leverage than a primary residence at comparable sizes — which changes the loan amount itself and can shift which reserve tier applies.
