With housing costs at record highs, more people are turning to house hacking — living in a property while renting out part of it to help cover the mortgage or rent. Done carefully, it can dramatically lower your housing costs.
This article is general information, not financial or legal advice. Local laws, lending rules and taxes vary, so speak with qualified professionals before making decisions.
Common ways to house hack
- Rent out a spare room to a long-term tenant.
- Buy a duplex, triplex or fourplex, live in one unit and rent the others.
- Add or rent an accessory dwelling unit (ADU) such as a basement suite or backyard cottage.
- Co-buy with friends or family to share costs.
What to check before you start
- Local zoning and rental rules — some areas restrict rentals or require permits.
- Your mortgage terms and insurance — make sure renting is allowed and covered.
- Realistic numbers — include repairs, vacancies and maintenance, not just rent.
- Tenant screening and a written lease — protect yourself and your home.
- Your lifestyle — sharing space requires clear house rules.
