How to Get a Mortgage on an Investment Property in 2026

Updated March 2026

The Requirements

For a conventional investment property mortgage in 2026: 15-25% down payment (15% for single-family, 25% for 2-4 unit), 660+ credit score (740+ for best rates), debt-to-income ratio below 45% (including the new mortgage), 6 months of cash reserves (mortgage payments) in the bank, and 2 years of tax returns showing stable income. Investment property rates run 0.5-0.75% higher than primary residence rates.

The DTI Trap

Debt-to-income ratio trips up a lot of investors. If you earn \$8,000/month gross and have \$2,500/month in existing debt (mortgage, car, student loans), your DTI is 31%. Adding a \$1,200 investment property mortgage pushes you to 46% — over the 45% limit. The fix: lenders count 75% of expected rental income as income. If the rental brings \$1,500/month, they add \$1,125 to your income side, bringing DTI back under the threshold.

The Documentation Checklist

Two years of tax returns (all pages, all schedules). Two months of bank statements (all pages — they check for large unexplained deposits). Pay stubs for the last 30 days. Proof of down payment source. If you own other rentals: leases for all current tenants and the most recent year of Schedule E from your tax return. If self-employed: two years of business returns and a profit-and-loss statement.

Timeline

Pre-approval: 1-3 days. Full underwriting: 2-4 weeks. Closing: 30-45 days from accepted offer. Speed tip: get pre-approved before you start shopping. A pre-approval letter makes your offer stronger and tells you exactly how much you can borrow. Without it, you're guessing at your budget and sellers won't take you seriously.
