How much does a two-family or income property cost in Roswell in 2026?

Roswell income properties price off the legal unit count, condition, and documented rent roll rather than one blanket number for the whole city. A duplex with a permitted second kitchen and current leases in hand draws different buyers than one being sold with unpermitted space, and appraisers treat the two very differently. Fulton County assesses at 40 percent of fair market value, but the sale price still comes from comparable closings, not the assessment. Joel Boss pulls those Roswell comparables before recommending a price.
