If this monthly payment fits your budget, you likely qualify for a preliminary discussion with a lender—the next step is a soft-pull rate check to see which commercial real estate lenders match your specific property type. Keep in mind that your actual rate depends heavily on your specific credit profile and the property's performance, not just the market average.
What changes your rate / answer
- Property Type: Multifamily property financing often secures lower rates compared to raw land, hospitality, or single-tenant retail due to lower risk profiles.
- Loan-to-Value (LTV) Ratio: A lower LTV—meaning you have more skin in the game—typically opens the door to the best commercial mortgage lenders and lower interest rates.
- Recourse vs. Non-Recourse: Non-recourse commercial loans often carry a slight rate premium because the lender takes on higher risk in the event of default.
- Amortization Period: Stretching your amortization from 20 to 25 or 30 years will significantly lower your monthly payment, though it will increase the total interest paid over the life of the loan.
- Credit/Experience: For smaller loans, the borrower's personal credit score remains a primary factor, while for larger institutional deals, the track record of the development team is the primary lever.
How to use this
- Principal: Input the loan amount you are seeking, not the total purchase price of the property.
- Interest Rate: Use a conservative estimate. If you are looking at current commercial real estate interest rates 2026, add 0.5% to account for potential origination fees or points.
- Term vs. Amortization: For a standard 20-year term, input 240 months. If you are looking at a 5-year bridge loan commercial real estate product with a 25-year amortization, set your term to 60 months and your amortization to 300 months.
- Interpret the Result: The resulting number is your P&I (Principal and Interest). This does not include taxes, insurance, or property management reserves, which you must add back in to determine your true cash flow.
Bottom line
Use this figure as your baseline for underwriting a deal. If the monthly payment exceeds 75-80% of your net operating income, you may need to reconsider your capital stack or debt structure to remain profitable.
