2–4 Unit Multi-Family Financing in Oak Park, IL

2–4 Unit Multi-Family investing in Oak Park

A 2–4 unit property in Oak Park is still residential financing — it is underwritten on the 1025 Small Residential Income Property appraisal rather than a commercial rent roll, so you keep 30-year fixed terms while spreading vacancy risk across multiple doors. Losing one tenant in a duplex costs you roughly half your income instead of all of it.

At the Oak Park median of $465,000, a 2–4 unit multi-family prices near $734,700 for a typical duplex — small multifamily trades at a premium per building but a discount per door. Minimum down is 25% ($183,675), leaving a loan of $551,025. Estimated all-in PITIA runs about $5,421 per month.
