The Quick Read: It depends on the lender, the loan size, and the transaction, but about 6 months of PITIA is a common benchmark across a wholesale network of DSCR lenders. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived, while larger loans typically step up toward about 9 months. Subject to lender guidelines, here is what moves the number:
- Reserves are liquid assets left after the down payment and closing costs, counted in months of the property’s monthly payment.
- Loan size moves the requirement more than any other single factor.
- Property count can add reserves, but the add-on varies by program, so ask each lender how it stacks.
- Cash-out refinances may let proceeds count toward reserves, depending on the program.
- Weaker coverage, thin credit, or a first-time STR can push the requirement up.
Short-term rental loans draw more reserve scrutiny than long-term rentals because the income is less predictable. This guide gives you a way to estimate your own number before you apply. It also shows the questions that separate lenders from each other.

Key Terms Defined
Reserves: Cash and other liquid assets you still hold after closing. They are not paid to the lender and are not the same as an escrow account.
PITIA: The monthly payment of principal, interest, taxes, insurance, and association dues on the property. Cornell Law School’s Legal Information Institute explains the PITI core of that payment.
DSCR: Debt service coverage ratio. Monthly rental income divided by PITIA. A 1.00 means rent matches the payment exactly.
Stacking: Adding reserves for each other financed property you own, on top of the reserves on the loan you are applying for.
Haircut: A discount a lender applies to certain assets, such as retirement balances, when it counts them as reserves.
Rate-term refinance: A refinance that changes the loan’s terms without pulling cash out of the property.
What Reserves Are (and What They Are Not)
Reserves are a cushion. The lender wants proof that you can keep paying the loan if a month or two goes badly. Short-term rentals make that more likely, because bookings swing with seasons and local demand.
Reserves sit on top of your other cash needs. You still need the down payment and the closing costs. Reserves are what remains after both are paid.
Many first-time buyers confuse reserves with the down payment. A bigger down payment lowers the loan and can lift the coverage ratio. It does not replace reserves, and it does not erase leverage caps, credit floors, or property rules. The strongest files clear two tests: enough equity and enough rental coverage.
The conversion is simple. Take the monthly PITIA, then multiply by the required months. A six-month requirement means six times the monthly payment, held as eligible assets. Your lender’s calculator or worksheet will give you the exact figure for your file.
How Does Loan Size Change the Requirement?
Loan size is the biggest lever. On most files in the network, reserves hover around 6 months of PITIA. Conservative rate-term files under $1,500,000 can see them waived. Past that size, requirements typically step up to about 9 months.
Loans above $2,500,000 are a different tier. The network generally holds those to 30-year fixed structures, and reserve expectations tend to sit at the high end. Standard programs run up to $3,000,000.
| Loan size | Typical reserve picture | What can change it |
|---|---|---|
| Under $1.5M | Often about 6 months; may be waived | Transaction type, leverage |
| $1.5M to $2.5M | Typically steps up toward about 9 months | Credit, coverage, leverage |
| Above $2.5M | Highest tier; 30-year fixed structures | Lender, full file review |
Those are ranges, not promises. Each lender sets its own number, and every file is underwritten individually.
One point surprises people. Reserves follow the payment, not the balance. A larger loan does not always mean proportionally more months. But because the payment is bigger, the same months cost more cash.
A smaller property with heavy taxes, insurance, and association dues can carry a bigger payment than its price suggests. It can need more cash in reserve than a larger, lightly burdened one. Read the PITIA, not just the loan amount.
Why Do Short-Term Rentals Get More Scrutiny?
Lenders look harder at STR income because it is less predictable than a signed lease. AirDNA, a short-term rental data provider, notes this same added scrutiny in its coverage of how DSCR works for rentals.
That shows up in the program rules. Across the network, STR purchases go up to 75% LTV. STR refinances run around 70%, and cash-out on short-term-rental collateral also tops out near 70%. Standard long-term rentals can reach 75% on cash-out. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Most STR programs expect a credit score of 640 or higher. They also expect about 12 months of hosting history, and a 1.00 coverage floor on purchases and on refinances alike. Those thresholds differ from long-term rental programs, so do not assume one set carries over. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Does the STR effect stack with the loan-size effect? Often yes, in practice. A large STR loan with thin coverage and limited hosting history is a bigger ask than any one of those traits alone. Lenders weigh the whole file, so each risk factor can push the reserve number up.
What About the Number of Properties You Own?
Property count is where lenders differ most. Some programs look only at the loan in front of them. Others add reserves for each other financed property you hold.
The idea is familiar from the agency world. Fannie Mae’s Selling Guide adds reserve requirements for second-home and investment loans as the number of financed properties grows. DSCR loans are not agency loans, though. Each DSCR program sets its own policy, so treat that as a concept, not a rule that governs your file. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Within the network, additional-property reserves vary by program. Some lenders add a modest amount for each other financed property. Others apply a flat rule once you pass a threshold. A few ignore the other loans and look only at the subject property. There is no single figure to quote, and anyone who gives you one without naming the program is guessing.
The practical questions to ask any lender are:
1. Do reserves apply to the subject loan only, or to my whole financed portfolio?
2. If other properties count, how many months per property, and is there a cap?
3. Can one pool of cash cover several loans, or does each loan need its own?
4. Does the answer change if I pay off or sell a property before closing?
Your answers let you build a range before you apply. Run the subject-only case and the stacked case. If both work, you have room.
Loan Size × Property Count: How the Two Combine
Because stacking varies by program, the cleanest way to view it is as a grid of direction, not dollars.
| Loan size | One financed property | Several financed properties |
|---|---|---|
| Under $1.5M | Base only; may be waived | Base plus a program add-on |
| $1.5M to $2.5M | Higher base | Higher base plus add-on |
| Above $2.5M | Highest base tier | Highest base plus add-on |
Read the grid this way. Loan size sets the base. Property count may add to it. Transaction type, coverage, and credit adjust the result up or down.
Here are three scenarios, with no dollar amounts because every file is priced on its own terms.
Picture a first-time STR buyer at 75% LTV on a loan under $1,500,000. This investor owns no other financed rentals. The file looks like the common case, with reserves around 6 months of PITIA, subject to the lender. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Say you own four financed rentals and want a fifth through a program that stacks. You owe the base for the new loan, plus whatever the program adds for the other four. Run that number before you bid.
Consider an investor buying above $2,500,000. This is the top tier, so expect the high end of the range and a 30-year fixed structure. Reserves here can be a real constraint even when the rental coverage is strong.
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.
What Moves the Number Up or Down?
Several factors adjust the base. Here is how they tend to work across lenders:
| Factor | Direction | Why |
|---|---|---|
| Coverage below 1.00 | Higher | Thinner cushion on the payment |
| Larger loan | Higher | Bigger payment, higher tier |
| Weaker credit | Higher | More risk on the file |
| First STR, short hosting history | Higher | Less proof of income |
| Conservative rate-term, modest leverage | Lower | Little new risk added |
Coverage below 1.00 deserves a plain explanation. Many select programs start at 1.00. A separate path through select lenders in the network takes coverage below 1.00, with leverage and terms adjusted. Reserves are typically part of that adjustment.
Clearing 1.00 also does not mean the property cash flows. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. Reserves protect against some of that, but only if you hold more than the minimum.
What Counts as Reserves?
Lenders accept liquid, documented assets. The details vary, so confirm each one up front.
- Checking and savings: The cleanest form. Lenders usually want a seasoned statement history, meaning the funds have sat in the account for a stretch.
- Brokerage and retirement accounts: Many lenders accept them but apply a haircut, so only part of the balance counts. The size of the haircut varies.
- Cash-out proceeds: On some cash-out refinances, proceeds can count toward reserves, depending on the program and property type. Lendmire’s piece STR Cash-Out Refinance Reserves: Six Months and When the Proceeds Count covers this in depth.
- Business accounts: If an LLC holds the funds, lenders typically ask for documentation of ownership and access, subject to lender program eligibility.
- Gifts and borrowed funds: Usually restricted. Ask before you plan on them.
Large, unexplained deposits trigger questions. If you move money between accounts, keep a paper trail. Do it well before you apply, so the statements are clean when the lender reviews them.
A Planning Checklist
Do the work early. Reserve problems rarely come from a lack of money. They come from money that cannot be documented.
1. Estimate the monthly PITIA on the subject property, including association dues.
2. Multiply by a range of months. Use about 6 as the middle case, and test lower and higher.
3. Add your down payment and closing costs. Reserves come on top.
4. Add furnishing and startup cash if you are buying a new STR. Those costs are not reserves, but they draw from the same pool.
5. List eligible accounts, and apply a haircut to retirement and brokerage balances.
6. Move any funds well before applying, and keep records of every transfer.
7. Ask the lender how it counts other financed properties.
Frequently Asked Questions
Do reserves differ for a short-term rental versus a long-term rental?
Often, yes. STR income is harder to predict, so lenders may ask for more cushion or look harder at the file. STR programs also carry their own leverage and credit expectations. Compare the full set of terms, not just the reserve months.
Can I use cash-out proceeds to satisfy reserves?
On some cash-out refinances, yes. The proceeds can count toward the requirement, depending on the program and the property type. Confirm this before you rely on it, since it changes how much outside cash you need.
Do reserves go up for each rental I already own?
That depends on the lender. Some programs add reserves for each other financed property, and others look only at the subject loan. Ask whether the number is per loan or portfolio-wide.
Are retirement accounts accepted as reserves?
Many lenders accept them, but typically with a haircut, so only part of the balance counts. The size of the discount varies by lender, so ask before you plan around a retirement balance.
Is a bigger down payment a substitute for reserves?
No. A larger down payment can lower the payment and improve the coverage ratio, but reserve rules, credit floors, and leverage caps still apply. The two requirements are separate tests.
Next Steps
The best preparation is a short list of numbers: your PITIA, the likely reserve months, and your eligible cash. If the gap between them is large, shop for a program that fits your portfolio.
