Analyze mortgage costs for investment property acquisitions
Why Investors Matters
Investment property mortgages have different terms, rates, and requirements than primary residence loans. Our calculator models investor-specific scenarios including higher down payments (typically 20-25%), higher interest rates (0.5-0.75% above primary residence rates), and the impact of rental income on qualification. Compare financing options to determine whether conventional financing, portfolio loans, or DSCR loans best fit your investment strategy.

Frequently Asked Questions
Most conventional lenders require 20-25% down for investment properties. Properties with 2-4 units may require 25% down. Some portfolio lenders and DSCR lenders offer programs with as little as 15% down, though rates and fees will be higher. VA loans cannot be used for pure investment properties, and FHA loans are limited to owner-occupied properties with up to 4 units where you live in one unit.
A Debt Service Coverage Ratio (DSCR) loan qualifies based on the property's rental income relative to its mortgage payment rather than the borrower's personal income and employment. A DSCR of 1.0 means rent equals the mortgage payment; lenders typically require 1.0-1.25x coverage. DSCR loans are popular with investors who have complex income or own multiple properties, as they do not require tax returns or employment verification.
Yes, most lenders allow 75% of the projected rental income (based on a market rent appraisal or existing lease) to offset the mortgage payment when calculating debt-to-income ratios. However, the property must appraise appropriately, and lenders may require documented rental history or a lease agreement. This income offset can significantly increase your purchasing power for investment properties.
