YOUR MORTGAGE, EXPLAINED
Can buying a duplex help me build wealth?
It can create housing and rental opportunities, but also adds property, financing and landlord responsibilities. Compare all costs, vacancy and cash reserves before relying on rent to make the payment. Loan eligibility and the amount of rental income that can be used depend on the program and documented circumstances.

Use conservative rent assumptions
Proposed rent is not the same as guaranteed income. Include vacant periods, collection risk and expenses. Ask the lender how any qualifying rent is calculated rather than using the entire advertised amount.
Understand occupancy and property rules
The number of units, intended use and program requirements matter. Explain your actual plan accurately. Do not represent an investment plan as owner occupancy to obtain different terms.
Budget the responsibilities
Insurance, taxes, legal obligations and other operating costs can differ from a single household home. Get qualified local and insurance advice before becoming a landlord.
Compare a simpler purchase
A duplex is not the only wealth path. Compare a home without rental income and the ability to save elsewhere. The arrangement should fit your life as well as a spreadsheet.
