Septic system on multifamily

[Sean Connolly]

Hello everyone.

I am currently looking at a property in my hometown. The property is two different buildings. A duplex: Two 1Bedroom/1Bath and one Single family 3Bed/1Bath. It has been on the market for 2years, and the price has been reduced from 430,000 to 339,900 over that time. Sellers are an elderly couple occupying the 3bedroom, looking to relocate after property is sold. Title V (Septic System) is buyers responsibility. My question is, are there any finances for owner/occupant that can add the septic system replacement into the loan? I thought of FHA 203K, but is that available to multifamily properties? Or just single families? Any other advice is appreciated. Thank you.
