Land Area States 0 on HCAD. Is This Good or Bad?

[Lauren Brown]

I have a lead in Houston, TX and while researching HCAD the Land Area states 0 SF and the total living area is 2,763 SF and will be a 4 bedroom 2.5 after remodel. The property has a class code of Single-Family and is in a class B area. The property has a closed in back patio and separate atrium and small lawn in the front but no back yard. The walk space on the each side of the house is very narrow. The property looks like a town home but is not connected to the homes on either side and is a SFR. My realtor has confirmed the comps, but he also stated the land area is 0 SF as opposed to the comps that have minimum lot sqft of 8,810.

My question is would this house be comparable to the comps when determining the ARV even though it's lot size is 0? Any advice and education on how to analyze the ARV on this type of property would be great.
