Zillow Advice: Buying Process - Cost difference between a single family vs. 2-family property? http://www.zillow.com/advice-thread/Cost-difference-between-a-single-family-vs-2-family-property/462357/ Zillow Advice | Zillow Real Estate You need to contact a couple ... http://www.zillow.com/advice-thread/Cost-difference-between-a-single-family-vs-2-family-property/462357/ You need to contact a couple of listing agents and ask them to provide you with a comparative market analysis CMA.&nbsp; When the appraiser does the appraisal of your property, it will be compared with&nbsp;similar properties.&nbsp; The listing agent you choose, will be able to identify the type of property, whether is was permitted as having an in-law apartment, or if it is permitted as a duplex&nbsp;&nbsp;or multi-family.&nbsp; The fact that this property provides you with an extra income, makes it already different from the one next door, and please disregard the Zestimates, they are not always accurate.&nbsp; It would be interesting what the assessed value of the two properties is, but only of interest, since that does not have much impact on the listing price.

Even though they started out the same, an appraiser would only compare duplexes with other duplexes.<br/><br/>You really need to talk to a couple of local Realtors and get their thoughts on what the home is worth. It could be a steal or it could be vastly over-priced. It all depends on the recent sales comps.
