Financing is part of the deal, not an afterthought
The same property can produce very different returns depending on how you finance it. Lenders also differ in how they treat short-term rental income. Program details, rates, and requirements change often, so use this guide to organize questions, then get current quotes from lenders who regularly finance short-term rentals.
Common loan types
Conventional (primary or second home)
Conventional loans that follow agency guidelines are often priced attractively. Occupancy classification matters: a primary residence, second home, and investment property are underwritten differently, and you must be honest about intended use. Lenders may or may not count projected rental income toward qualification, depending on the program.
DSCR loans
Debt service coverage ratio loans qualify the property on its income rather than your personal income. DSCR = property income divided by debt payments. Rates and down payments are frequently higher than conventional loans, but they can suit investors with complex income or many properties. See our post on DSCR loans for STR investing. Ask how the lender measures short-term rental income (trailing history, appraiser projections, or a market data report).
Portfolio and local bank loans
Some community banks keep loans on their own books and can be flexible on terms, which sometimes helps with unusual properties. Terms may include balloon payments or adjustable rates.
Home equity or HELOC
Investors sometimes use equity in another property. This ties the risk to the other property, so consider the consequences of a shortfall.
Seller financing
The seller acts as the lender. Terms are negotiable, but contracts should be reviewed by an attorney, and due-on-sale clauses on any existing mortgage can create serious problems.
Private or hard money
Short-term, higher-cost loans typically used for purchase and renovation before refinancing. Refinancing is not guaranteed, so plan for the possibility that you may need to hold the loan longer.
What lenders typically examine
- Credit score and history
- Down payment and reserves (months of payments in liquid accounts)
- Debt-to-income ratio, for income-based loans
- Property type and condition
- Rental income documentation for DSCR programs
- Entity structure, if borrowing through an LLC (see our legal structure guide)
Step-by-step approach
- Decide your target cash-on-cash return and maximum cash outlay.
- Collect quotes from at least three lenders, including one specialized in investment or STR lending.
- Ask each lender for a written estimate covering rate, points, closing costs, prepayment penalty, and reserves required.
- Model each quote in your underwriting spreadsheet.
- Check how the lender treats rental income and whether they need a permit in place.
- Align timing: appraisal, permit approval, and closing date.
Worked payment example
Example (illustrative only): Purchase price $500,000, down payment 25 percent ($125,000), loan $375,000, interest rate 7 percent, 30-year amortization. The standard payment formula is P = L x [r(1+r)^n] / [(1+r)^n minus 1], where r is the monthly rate and n the number of payments. With r = 0.07/12 and n = 360, the monthly principal and interest is about $2,495, or roughly $29,900 per year.
Now compare two structures at the same price: a 20 percent down loan at 6.75 percent versus a 25 percent down loan at 7.25 percent. The second requires $25,000 more cash but the difference in the payment is roughly a few hundred dollars per month. Whether the extra cash earns more elsewhere is the real question. Run both in your model.
DSCR example
Example (illustrative only): Annual NOI $45,000 and annual debt payments (including taxes and insurance, depending on lender definition) of $36,000 give DSCR = 1.25. Many lenders set a minimum; the threshold varies by program. If a lender wants 1.25 and your DSCR is 1.05, you may need to increase the down payment or find a different property.
Compare beyond the rate
- Points and lender fees
- Prepayment penalties, common on DSCR loans
- Fixed versus adjustable rate, and reset dates
- Interest-only options and their effect on later payments
- Reserve requirements
- Cross-collateralization clauses
- Ability to refinance or sell without penalty
Common mistakes
- Misrepresenting occupancy intent on a loan application
- Choosing a loan on rate alone without counting fees and required reserves
- Underwriting using an interest rate you have not been quoted
- Adding leverage that leaves no cushion for a slow season
- Assuming you can refinance later at a better rate
- Forgetting that a lender's rental income estimate may be lower than yours
Pair this with down payment strategies to plan cash needs.
Preparing your application package
Lenders respond well to organized files. Gather two years of income documents if the program requires them, recent bank and investment statements, identification, entity documents if borrowing through an LLC, and a summary of your other real estate. For DSCR loans, prepare rental income estimates and any available booking history.
Questions to ask a lender
- How do you calculate income for a short-term rental?
- Is there a minimum ownership or seasoning period?
- What are the prepayment terms?
- Will you lend to my LLC, and what guarantees are needed?
- What is the timeline from application to closing?
Get quotes on the same day if possible, since rates move. Write them into a comparison table, and note the total cash required at closing for each option.
