The answer is no. This is because the property has to be specifically zoned as a multiunit property in order for the income to be used for the purposes of qualifying for a mortgage. In order for the income to be counted the property must be a duplex, triplex or four plex and it must be zoned as such, the property use has to be one of those following things. If the property is zoned as a single-family residence and it just happens to have a granny it on the back of it, while it’s wonderful that you’re getting that additional income unfortunately can’t be used to offset the monthly liability.

It’s because the property was not designed for rental income purposes that the income cannot be used. Additionally there’s not much for an appraiser to compare it to because properties with granny units are far and few, beyond that there’s a certain level of questionable uncertainty in income from a granny unit because it’s not a consistent income source despite the lease agreement and/or relationship you have with that tenant.
