As of Oct 22, 2026 · General Freddie Mac market benchmark, not a Lendmire loan offer. Nightly rate, occupancy, taxes, and insurance are editable estimates. Qualifying income for short-term rentals varies by program — some use appraisal market rent, others use documented STR history or projections — and is confirmed in underwriting. Not a Loan Estimate, approval, or commitment to lend. Program availability and eligibility are subject to lender guidelines, credit approval, property review, and underwriting.
The Quick Read: Reserves on a short-term rental DSCR loan are not one fixed number. They move with loan size, leverage, transaction type, and how many properties you already finance, and each lender program sets them. Across the wholesale network Lendmire works with, the common expectation is about 6 months of PITIA, with rate-term files at modest leverage under $1,500,000 sometimes seeing reserves waived. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
- Reserves are documented liquid funds left over after the down payment, closing costs, and prepaids.
- Loans above $1,500,000 typically step up to about 9 months of PITIA.
- Property count matters through program design: some programs stack reserves per financed property, others do not.
- STR purchases reach up to 75% LTV on the strongest files, with a 640 minimum score and a 1.00 coverage floor.
- Reserve cash competes with your down payment for the same pool of liquid capital.
Most short-term rental investors plan for the down payment and closing costs, then get surprised by the third bucket. That bucket decides whether a deal clears review. What follows covers the mechanics, the loan-size ladder, how property count changes the math, and where the general rules break.
What Are Reserves, and Why Do STR Files Get Extra Attention?
Reserves are liquid assets you still hold after closing. They are measured in months of the subject property’s full housing payment: principal, interest, taxes, insurance, and association dues (PITIA). Multiply the monthly obligation by the required months and you get your target.
The same “6 months” can mean very different cash on different properties. A mountain cabin with high insurance and a condo with heavy dues carry different PITIA even at the same price. That is why reserve planning starts with the payment, not the purchase price.
Short-term rentals draw more scrutiny because income swings with season, platform changes, reviews, and property condition. AirDNA’s discussion of debt service coverage explains why STR income variability gets extra lender attention. Reserves are the cushion that answers that volatility. Within Lendmire’s network the more common pattern is about 6 months, rising with loan size, subject to lender guidelines.
DSCR itself compares rent to PITIA only. Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities, and capex sit outside the calculation. Reserves required by the lender are also separate from the operating cushion a prudent host keeps for slow months. Exact terms depend on lender and investor guidelines, credit profile, reserves, and property review.
Who Sets the Number?
No regulator sets reserves for DSCR loans. These are business-purpose, non-QM investor loans, and the federal consumer-finance regulator‘s repayment-capacity rule overview shows why: the qualified-mortgage framework governs owner-occupied consumer lending, and loans outside it leave underwriting standards to each lender. Reserves are a program overlay.
Agency rules do not apply either. DSCR is not an agency product, so conforming-loan reserve formulas do not carry over. The only agency touchpoints are the appraisal form names that DSCR files borrow. Fannie Mae’s forms page lists Form 1007, the rent schedule for one-unit properties, and Form 1025, the small residential income property report used on 2-4 units. Neither is an STR form. Both document long-term rent, and STR files add booking history or a third-party projection on top.
How Underwriting Treats Reserves, Step by Step
1. The lender sets months of PITIA. The base comes from the program, then adjusts for leverage, loan size, coverage ratio, credit, and transaction type.
2. Your PITIA converts months into dollars. Taxes, insurance, and dues change the target, so get real figures early.
3. Reserves are measured after closing. Down payment, closing costs, and prepaids come out first. What remains is what counts.
4. Funds are documented. Bank or brokerage statements evidence the cash. Large recent deposits trigger sourcing questions, and funds generally need to sit in the account for a period.
5. The reserve test runs next to the coverage test. Passing one does not waive the other.
The file also includes entity documents if you borrow through an LLC, a credit report, the purchase contract, an appraisal with rent schedule, an insurance binder, and STR income evidence such as trailing platform statements or a projection. Qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines, though asset statements are always part of the package.
Reserves by Loan Size: The Ladder
Loan size is one of the strongest drivers of the reserve requirement. Here is how it typically plays out across the network, as a guide rather than a promise.
| Loan size | Typical reserve expectation | What changes |
|---|---|---|
| Under $1,500,000, rate-term, modest leverage | Often waived on conservative files | Strong credit and lower LTV help |
| Under $1,500,000, purchase or higher leverage | Commonly around 6 months PITIA | Leverage and credit move it |
| Above $1,500,000 | Typically about 9 months PITIA | Step-up applies to larger balances |
| Above $2,500,000 | Generally 9 months or more; 30-year fixed only | Term options narrow |
Standard programs run up to $3,000,000, and smaller balances route through select lenders in the network. The step-up above $1,500,000 is why a modest loan-size reduction can change the reserve tier. An investor sitting just over the line might compare a slightly larger down payment against holding three extra months of PITIA. For a high-PITIA property, that three-month gap can exceed the extra equity needed.
A bigger down payment lowers the monthly payment and can lift coverage. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Reserves by Transaction Type
Purchase, rate-term, and cash-out files treat reserves differently.
| Transaction | STR leverage ceiling | Reserve pattern |
|---|---|---|
| Purchase | Up to 75% LTV | Commonly about 6 months PITIA |
| Rate-term refinance | Around 70% LTV | Can be waived at modest leverage under $1,500,000 |
| Cash-out refinance | Up to 70% LTV on STR collateral | Program-dependent; weakest at large balances |
STR purchases reach 75% LTV on the strongest files; the 70% ceiling applies to refinance and cash-out on short-term-rental collateral. Expect a 640 minimum score, about 12 months of hosting history, and a 1.00 coverage floor on both purchases and refinances. Standard long-term rentals differ: purchase leverage mostly lands at 75% to 80% LTV and cash-out tops out around 75% LTV, with about 6 months of seasoning common. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Whether cash-out proceeds can count toward reserves depends on the program. Some count them, and the treatment tends to tighten as balances grow. Do not plan on proceeds covering reserves for a large file without confirming first.
How Does Property Count Change Reserves?
Property count changes reserves through program design, not through a universal rule. Three models exist, and which one applies depends on the program you are placed in.
| Model | How it works | Who it favors |
|---|---|---|
| Subject-only | Reserves cover the new loan’s PITIA only | Investors building quickly with thin liquidity |
| Stacked per property | Subject property plus added months on each other financed property | Programs wary of portfolio exposure |
| Exposure-based | Extra reserve once total balances pass an internal ceiling | Very large portfolios |
Some programs do not multiply reserves by the number of properties owned. Others stack them. Both exist inside the same wholesale network, which is exactly why comparison matters. Practitioner comments in a BiggerPockets forum thread on scaling to 20+ doors say there is no cap on the number of DSCR loans beyond liquidity, and that very large guarantor exposure can trigger an added reserve tied to outstanding balances. That is anecdotal rather than a rule, but it points at the real limit: liquidity, not a loan-count ceiling.
A practical read of the three models: if your liquid capital is thin and your portfolio is growing, a subject-only program is easier to scale. If you hold substantial cash, a stacking program may still be the right fit on pricing or leverage. Reserves are one input, not the deciding one.
Loan Size and Property Count Together
Loan size and property count interact. Picture three investors.
- First STR, loan under $1,500,000, purchase. Reserves commonly sit around 6 months of the subject PITIA. Nothing stacks because nothing else is financed.
- Third STR, loan under $1,500,000, subject-only program. The reserve target is still about 6 months of the new property’s PITIA. A stacking program would add months tied to the two existing loans.
- Fifth STR, loan above $1,500,000. The step-up to about 9 months applies to the subject loan. In a stacking program, added months on four other financed properties compound it, and exposure-based overlays may come into play.
Which matters more? For most investors, loan size moves the number more predictably, because the step-up is a published tier. Property count matters mainly when the program stacks, and then it can dominate. The flip point is the first jumbo file in a stacking program: that is where the two drivers multiply, and where checking program design before choosing a loan amount pays off most.

What Counts as a Reserve, and What Doesn’t
Cash in checking and savings is the cleanest. Brokerage accounts are commonly accepted, often at a discount from market value, and retirement accounts can count at reduced value depending on the program. Gifts and borrowed funds, or assets already pledged, generally do not qualify. The agency reserve framework draws a similar line between liquid and unacceptable sources, but DSCR programs set their own treatment.
Home equity is a special case. Some industry sources report that a few lenders count equity in other investment properties, while many do not because equity is illiquid. Treat it as program-specific and uncommon.
STR investors have a few extra wrinkles:
- Business and LLC accounts. Funds held in the borrowing entity’s account can work when documented clearly, subject to program terms.
- Platform payouts. Money that has landed in a bank account is cash. Money still sitting on a platform is not documented funds.
- Commingled accounts. Mixed personal and operating funds make sourcing harder and are a common reason verification stalls.
- Foreign nationals. Reserves usually must sit in US-based accounts, which many foreign borrowers lack.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
Where the General Rule Breaks
Sub-1.00 coverage. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted, and reserves typically tighten along with them. That is a separate path from the select programs that set 1.00 as their coverage floor.
No-ratio files. These are available only through select lenders, generally for borrowers who already own a primary residence, and they carry different pricing and leverage.
Blanket loans. A portfolio loan secured by several properties is one note with one reserve calculation, which differs from per-property loans. It can simplify the math or complicate it, depending on balance and program.
Ineligible properties. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in the network’s DSCR programs, so reserve rules never come into play for them.
Condotels and restricted markets. Eligibility can shift the program, and with it the reserve rule. 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.
Why Do STR Reserve Files Fail Verification?
Most failures are about the cash, not the number. Typical culprits:
- A large deposit with no paper trail.
- Funds that have not been in the account long enough.
- Balances already earmarked for the down payment or another closing.
- Retirement or brokerage values counted at full value when the program discounts them.
- Mixed personal and business funds.
Broker-side experience points to one habit that prevents most of these: pull statements early, flag any recent transfer, and move funds well before contract rather than after. Where several loans are in motion, a new lender may not net out cash already earmarked elsewhere, so each file should stand on its own funds.
A Pre-Offer Checklist
1. Pick the property and get realistic taxes, insurance, and dues to estimate PITIA. 2. Choose a loan size, and check whether it crosses the $1,500,000 step-up. 3. Add up down payment, closing costs, prepaids, and reserves as one total. 4. Confirm whether your target program stacks reserves across financed properties. 5. Confirm which accounts count, and at what value. 6. Keep a separate operating cushion for slow months; lender reserves are not that cushion.

Key Terms Defined
PITIA: The full monthly housing obligation: principal, interest, taxes, insurance, and association dues.
Reserves: Liquid assets you still hold after closing, measured in months of PITIA.
Stacking: A program design that adds reserve months for other financed properties on top of the subject property.
DSCR: Monthly rent divided by PITIA, a coverage ratio that shows how well the property income covers its payment.
Seasoning: The period funds must sit in an account, or the period a property must be owned, before a program counts it.
Frequently Asked Questions
Do reserves apply to the new property only, or to every property I own?
It depends on the program. Some programs set reserves on the subject property alone, while others stack added months for each other financed property. Both exist within the network, so confirm the model before you choose a lender. Property count rarely caps the number of loans on its own; liquidity is the practical limit.
Can reserves be waived on an STR loan?
Sometimes, but not often. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived. STR purchases and cash-out files rarely qualify for a waiver, since income variability is part of why reserves matter on short-term rentals.
Can cash-out proceeds count as reserves?
Some programs count them, others do not. The treatment is weakest at larger balances. Plan as though proceeds will not count until the program confirms otherwise.
Do retirement and brokerage accounts count?
Commonly yes, often at a discount from market value, depending on the program. Gifts, borrowed funds, and already-pledged assets generally do not count. Documentation and seasoning rules apply to every account type.
Is a bigger down payment a substitute for reserves?
No. A larger down payment lowers the payment and can lift coverage, but reserves are measured after the down payment is paid. Both requirements have to be met separately.
