Getting Your Side of the Duplex Ready to Sell

How to prepare the unit you have lived in when selling a duplex, including what to disclose about shared systems and past repairs.

Living in one half of a duplex while renting out the other teaches you things a typical homeowner never has to learn. When it comes time to sell, that knowledge is worth putting on paper, because a buyer stepping into the same setup will want it.

Start with the shared systems. Note what is separate between the two units and what is not, whether that is utilities, water shutoffs, the roof, or the exterior. A buyer evaluating this property is trying to figure out where their responsibility begins and where a shared cost might come up later. Clarity here saves questions during inspection.

Pull together your repair history for both sides of the building, not just the unit you occupied. If you handled maintenance calls yourself, a record of what came up and how it was resolved tells a buyer what kind of upkeep this property actually requires, rather than what it might require in theory.

Walk through your own unit the way you would if you were the tenant moving in next, not the owner moving out. Small issues that you tolerated because you knew the property intimately, a sticking door, a slow drain, may read very differently to someone who is deciding whether to live there and manage a rental at the same time.

Be straightforward about anything that affected you as an owner-occupant landlord specifically, like noise between units or how sound travels through shared walls. A buyer who is about to live in the same setup would rather hear it from you than discover it after their first week.

A duplex sale rewards preparation because the buyer pool is smaller and more particular. The people looking at this kind of property are weighing a house and a small business at the same time. The more clearly you can describe both halves of that decision, the easier it is for them to say yes.
