How Much Are Reserves On An Airbnb Loan — The Quick Read: Most Airbnb loan programs want somewhere between 6 and 9 months of PITIA sitting in liquid, verifiable accounts after your down payment and closing costs are covered. Smaller, lower-leverage files sometimes see that requirement waived. Larger loans, or ones with weaker coverage ratios, usually get pushed higher. There is no single number — it moves with loan size, leverage, credit, and how the property’s rental income pencils out.
If you came here hoping for one clean figure, the honest answer is that reserves are a range, not a rule. But the range is a lot narrower and more predictable than most first-time investors expect once you understand what’s actually driving it.
What Are Reserves, Exactly?
Reserves are cash (or near-cash assets) left over in your accounts after your down payment and closing costs are already spent. They’re not part of the transaction — they’re proof you can survive a slow month without missing a payment.
Lenders aren’t asking whether you can afford to buy the property. They already know that from your down payment. What they want to know is whether you can keep paying the mortgage if a booking calendar goes quiet for a few weeks, if the water heater dies in month three, or if a slow shoulder season shows up right after closing. Reserves are the buffer that answers that question.
The standard unit lenders use is PITIA — principal, interest, taxes, insurance, and association dues (HOA, if applicable) — added together as one monthly obligation. Reserves get quoted as “months of PITIA,” which is why you’ll hear a lender say something like “six months reserves” instead of naming a dollar figure. The dollar amount depends entirely on your specific property’s monthly obligation, which is why nobody can give you a flat number without knowing the deal.
Key Terms Defined
- PITIA: the full monthly housing obligation — principal, interest, taxes, insurance, and association dues combined into one number.
- DSCR (Debt Service Coverage Ratio): a ratio comparing the property’s rental income to its PITIA. A DSCR of 1.00 means the rent covers the payment exactly; above 1.00 means it covers more than the payment.
- Business-purpose loan: a loan made for an investment property rather than a home you live in. This distinction matters because business-purpose loans are underwritten differently than a typical owner-occupied mortgage.
- Seasoning: how long you need to have owned an asset, or how long funds need to sit in an account, before a lender counts them cleanly.
- LTV (Loan-to-Value): the loan amount expressed as a percentage of the property’s value or purchase price — a lower LTV means more equity, or a bigger down payment, relative to the loan.
Does Reserve Math Change for DSCR Loans vs. Conventional Loans?
Yes — reserves on a property-income loan work as a separate, parallel check from the coverage ratio, not a substitute for it. A DSCR loan is reviewed around whether the property’s rental income covers its own payment, but reserves are underwritten on top of that ratio, not folded into it.
That distinction trips people up constantly. A file can show a coverage ratio comfortably above 1.20 and still get a reserve condition from underwriting — because the ratio and the reserve requirement are answering two different questions. The ratio asks “does the rent cover the payment on paper.” Reserves ask “what happens if it doesn’t, for a month or two.” A strong DSCR does not waive the reserve check on its own. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
For a full walkthrough of how DSCR loans qualify borrowers on property income instead of personal income documentation, Lendmire’s complete DSCR loans guide breaks down the mechanics start to finish.
How Much Reserve Do STR (Airbnb) Loans Typically Require?
Short-term rental files generally run at the higher end of the reserve spectrum compared to a standard long-term-lease DSCR loan — commonly landing around 6 to 9 months of PITIA, with the exact number shaped by leverage, loan size, and hosting history. Airbnb income is treated as more variable than a signed 12-month lease, and reserves are the mechanism lenders use to absorb that variability on paper.
Across the wholesale network Lendmire (NMLS# 2371349) works with, short-term rental purchase loans typically top out around 75% LTV, with refinances running closer to 70% LTV. Most programs want to see a credit score around 700 and roughly 12 months of landlord or hosting experience before approving the strongest terms. On the income side, purchases generally need coverage at or above a 1.00 baseline, and refinances carry their own separate 1.00 baseline — these are not blended into one number, because a purchase file and a refinance file are underwritten with different risk profiles from the start.
Reserve figures on these files also scale with loan size. A conservative rate-and-term refinance at modest leverage under $1.5 million can sometimes see the reserve requirement waived entirely on a strong file. Push past that size, and most lenders in the network step reserves up toward 9 months. It’s not a hard cliff — it’s a sliding scale that tracks with how much exposure the lender is carrying. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
For investors specifically eyeing STR-only financing structures, Lendmire’s DSCR loan for Airbnb page covers the program-specific mechanics in more depth.
What Counts as an Eligible Reserve Asset?
Cash in checking and savings counts at full value. Business bank accounts generally count too, provided the funds are clearly yours and sourced cleanly. Stocks, bonds, and retirement accounts can often be used, but lenders typically apply a discount — sometimes called a haircut — before crediting them toward your reserve total, since those assets aren’t as instantly liquid as cash and can lose value.
What generally doesn’t count: borrowed funds, unsecured loans, gifts that haven’t seasoned in your account, and anything you can’t document with a clean paper trail. Lenders verify reserves the same way they verify any asset — recent bank or brokerage statements, usually the last two months, with any large or unexplained deposit subject to a documentation request. This isn’t a special STR rule; it’s standard asset verification applied to the reserve requirement specifically.
What Can Lower or Raise Your Reserve Requirement?
These specifics are subject to lender guidelines and a full review of property, leverage, and credit. Reserve tiers move with the deal’s overall risk profile — loan size, leverage, credit tier, and how many other financed properties you already own all push the number up or down. Nothing here is fixed, but the direction each factor pulls is consistent across the network.
- Loan size. Smaller, more conservative loans see lighter reserve requirements. Cross into larger balances — especially above roughly $2.5 million, where the network generally holds to 30-year fixed structures anyway — and reserves climb accordingly.
- Leverage. Files at maximum LTV get treated more conservatively than files with more equity in the deal. A bigger down payment lowers your payment and can lift your coverage ratio, but it doesn’t erase a reserve condition on its own — the strongest files clear both the equity test and the coverage test.
- Credit tier. A 620 floor exists in parts of the network, but most programs want closer to 660, and a 700+ score is generally what unlocks the strongest leverage tiers — which often carries a lighter reserve ask alongside it.
- Coverage ratio. Files landing below a 1.00 baseline on long-term rent assumptions are still reviewable through select lenders in the network, but leverage and terms adjust to compensate — and reserves are typically part of that adjustment.
- Portfolio size. If you already own several other financed rental properties, some lenders want reserves not just on the property you’re buying, but a smaller reserve cushion stacked across each existing financed property in your portfolio. This is one of the biggest surprises for investors scaling past two or three doors — the reserve math isn’t just about the new deal anymore.
- Cash-out proceeds. On some refinance structures, proceeds from a cash-out transaction can be used to satisfy part of the reserve requirement on that same file — worth asking about directly if you’re pulling equity and need to show reserves at the same time.

A Practitioner’s Read on Where Files Get Stuck
Across the DSCR files that come through wholesale channels, reserves are consistently where an otherwise clean application hits friction — not the down payment, not even credit. An investor shows up with strong equity, a solid score, and a coverage ratio that clears comfortably above 1.00, then underwriting comes back asking for months of PITIA sitting untouched in an account. Files with STR income specifically, where there’s no 12-month booking history yet, tend to draw the most scrutiny here, because the lender is underwriting a projection rather than a proven lease. The fix is almost always the same: know your reserve number before you make an offer, not after you’re already under contract.
Purchase vs. Refinance: Does the Reserve Number Change?
Yes, though not dramatically — purchase and refinance transactions are underwritten as distinct scenarios, and STR purchases and STR refinances each carry their own separate coverage baseline rather than one shared number. On the leverage side, purchase loans generally reach higher LTV than refinances, since a refinance is pulling against equity already built into the property rather than financing a new acquisition.
Cash-out refinances add a wrinkle worth knowing: seasoning. Most lenders in the network want to see roughly 6 months of ownership before a cash-out refinance is considered, and cash-out LTV on these deals tops out around 70% for short-term rental properties specifically — never confuse that with the higher ceiling available on a straight purchase. If reserves are tight on a refinance, ask specifically whether cash-out proceeds can be applied toward satisfying the requirement, since some structures allow it.
What Reserves Are Not
Reserves are not proof of positive cash flow. A property clearing 1.00 coverage means rent equals PITIA — it says nothing about repairs, vacancy between guests, property management fees, utilities, or the capital expenses that come with running a short-term rental. Those costs sit entirely outside the DSCR calculation. Reserves are also not your down payment — they’re what’s left in the bank after the down payment and closing costs are already spent, which is the single most common point of confusion for first-time STR investors mapping out their cash-to-close.
Property types matter here too. Manufactured homes (single- and double-wide), log homes, and barndominiums fall outside the DSCR programs available through the network entirely — reserve questions are moot on those, since the property type itself isn’t eligible.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage, and reserve requirements are set by individual lender risk appetite rather than a fixed federal rule. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
If you’re weighing an Airbnb purchase against a standard rental buy-and-hold, it’s worth comparing how each financing path treats income and reserves — Lendmire’s breakdown of DSCR vs. conventional investment loans lays that out side by side.

Frequently Asked Questions
Do reserves include my down payment and closing costs?
No. Reserves are calculated as what’s left over after the down payment and closing costs are already accounted for. Lenders want to see that separate cushion sitting untouched in your accounts, not the money you’re about to spend to close the deal.
Can retirement accounts count toward my reserve requirement?
Often yes, but typically at a discounted value rather than dollar-for-dollar. Lenders generally apply a haircut to stocks, bonds, and retirement funds since they’re not as instantly accessible as cash, and the exact discount varies by lender and program.
Does a strong rental income projection reduce how many months of reserves I need?
It can factor into the overall risk picture, but a strong coverage ratio doesn’t automatically waive a reserve condition. Reserves and DSCR are evaluated as separate, parallel checks — clearing one doesn’t eliminate the other.
Do I need more reserves if I already own other rental properties?
Often yes. Some lenders in the network require reserves not just on the property you’re financing, but a smaller reserve cushion stacked across each other financed property already in your portfolio. This becomes a bigger factor as investors scale past two or three doors.
Can I use cash-out refinance proceeds to satisfy my reserve requirement?
On some refinance structures, yes — certain programs allow proceeds from a cash-out transaction to count toward the reserve condition on that same loan. It’s a detail worth asking about directly if reserves and cash-out timing overlap on your file. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Are reserve requirements different for a brand-new Airbnb listing with no booking history?
Generally yes. Properties without a documented rental track record are underwritten on projected income rather than proven income, and some programs respond to that added uncertainty with a higher reserve expectation until the listing has a real operating history behind it.
