Fannie Mae Investment Property Guidelines 2026: LTV, Reserves, and Financed Property Limits

Fannie Mae sets specific LTV caps, reserve requirements, and property count limits for investment property loans. Getting these wrong at submission costs time and often the deal.

Investment property loans through Fannie Mae require significantly more equity, larger reserves, and stricter credit than owner-occupied transactions. MLOs who confuse owner-occupied pricing with investment property pricing commit to terms they cannot deliver. Know the actual numbers before quoting.

LTV Caps for Investment Properties

  • 1-unit investment property purchase: max 85% LTV (15% down)
  • 1-unit investment cash-out refinance: max 75% LTV
  • 2-4 unit investment property purchase: max 75% LTV (25% down)
  • 2-4 unit investment cash-out refinance: max 70% LTV
  • These are program maximums; lender overlays often tighten these further

Reserve Requirements

Fannie Mae requires 6 months of PITIA reserves for each investment property the borrower holds, including the subject property. For borrowers with 1 to 6 financed properties, this applies to each financed property. For 7 to 10 financed properties, 6 months PITIA for each financed property must be documented. Reserves must be liquid: checking, savings, or money market accounts. Vested retirement accounts count at 60%.

Rental Income Calculation

For investment properties the borrower already owns and rents, Fannie Mae requires one of these three income sources: signed lease agreement, 2 years of Schedule E from tax returns, or a property management agreement plus bank statements showing rent deposits. If the property is being purchased, the appraiser's market rent from Form 1007 at 75% is used. The 25% vacancy factor is automatic.
