If this monthly payment fits your budget and cash flow targets, you likely qualify for financing—the next step is a soft-pull rate check with a lender who understands STR operations. Keep in mind that your actual interest rate will depend heavily on your individual credit profile and the specific asset class of the property.

What changes your rate and answer

When evaluating your borrowing power, small adjustments to your strategy can significantly impact affordability and your ability to secure funding. To get a more accurate picture, consider how these factors shift your numbers:

• Credit Score: Lenders reserve the best investment property mortgage rates 2026 for scores above 740. A lower score typically triggers higher rate tiers or requires a higher down payment to offset risk.

• DSCR Calculation: If you are pursuing DSCR loans for short term rentals, the lender will calculate affordability based on projected rental income rather than your personal income. If the projected revenue is too close to your debt payments, your affordability drops or you may be denied.
• Property Type: Financing a single-family home versus a multi-unit property often triggers different rate tiers, reserve requirements, and sometimes even varying DSCR threshold requirements.

How to use this

Use this tool to stress-test potential deals before you commit to an offer. Follow these steps to interpret your results accurately:

• Input Realistic Purchase Price: Enter the total purchase price of the property you are eyeing. Ensure this figure includes renovation costs if you are utilizing a financing structure that bundles acquisition and upgrades.
• Adjust Down Payment Percentage: 20% is typical, but note that 25% often unlocks the best terms. Test different percentages to see how they impact your monthly cash flow.
• Set Conservative Income Estimates: Use the most conservative estimate for monthly rental income. Do not use peak-season numbers; base your projections on annualized, occupancy-adjusted revenue.
• Analyze the DSCR: If your "Net Monthly Cash Flow" result is negative, or your DSCR is below 1.0, you may need to renegotiate the purchase price, increase your down payment, or look for a property with stronger occupancy potential to ensure the deal supports itself.
