Guide Duplex Due Diligence Without Predicting Returns

A duplex buyer may ask an agent to confirm that a property will produce income. The useful response gathers the buyer’s intended use, separates records from projections, and creates a due diligence path. An agent can locate listing materials and request available leases, expense records, and registration information. Those documents need independent review before a buyer makes an investment decision.

Rina plans to live in one unit and rent the other. One unit is vacant, and she asks what rent she can charge. Start with questions about her timeline, reserves, renovation plans, and information she needs before making an offer. Explain that rental rules, lease terms, operating costs, and income vary. A property manager, attorney, tax professional, or lender may each have a separate role.

In a fictional consultation, Rina says, “Will this definitely cash flow?” Theo answers, “I cannot predict that result. I can help you collect the current lease, the seller’s available expense history, and the local registration information. Then you can review the numbers with advisers you choose.” Rina asks for a rent figure. Theo says, “I can share advertised rentals as market context and label their dates and features. A qualified professional can help you evaluate allowable rent and your assumptions.”

Practice by giving the agent a listing sheet with one missing lease document. The agent should state what is known, ask permission to request the missing record, and identify who can answer a regulation question. Review whether the final step belongs to the buyer and includes a date for follow-up.
