Investment Property Financing: How It Differs From a Primary Home Loan

A mortgage for a rental or investment property looks similar to a primary home loan on the surface, but underneath, the rules change significantly. Lenders view investment properties as higher risk — the assumption being that if a borrower faces financial trouble, the rental property is more likely to be sacrificed than the home they live in.

What’s different about investment property financing:

• Down payments typically start at 15% to 25%, well above primary home minimums
• Interest rates run higher, often 0.5% to 0.875% above primary home rates
• Credit score expectations are stricter, usually 680+ for the best pricing
• Cash reserves of 6 months or more are commonly required, sometimes per property
• Rental income can sometimes be counted toward qualifying, but typically only 75% of projected rent

What lenders look at most closely:

• Your debt-to-income ratio with the new mortgage included
• Whether the property’s projected cash flow supports the loan
• Your experience as a landlord (some programs favor experienced investors)
• The condition and rental potential of the property itself

For experienced investors, portfolio loans, DSCR loans, and other non-QM products open additional doors when conventional financing falls short. These loans focus more on the property’s income than on your personal financials.

The takeaway: investment property financing is available and well-developed, but it rewards preparation, cash reserves, and clear projections. Buyers who treat the deal like a business — not just another mortgage — tend to qualify more smoothly and at better terms.
