Living in one unit of a duplex

Varies

Can You Write Off Living in One Unit of a Duplex?

Short answer: Split costs by unit: the rented unit's share of mortgage interest, taxes, insurance, repairs, and depreciation goes on Schedule E; your unit's share is personal.

Repairs to only the rented unit are fully deductible.

Records to keep: Keep leases, receipts, a log of repairs vs improvements, mileage to the property, and closing statements.
