When the agent said that an appraiser will adjust for different-sized homes at $80 per s.f. – that is just for the size of the home only. Say if there are two homes in a tract – one with 2000 sf and one with 2500 sf – the sale prices of the two homes might be different by $80 x 500 s.f. = $40,000. Let’s say a 2000 s.f. house sells for $600,000 – ($300 per s.f.). But of the $600,000 sale price, maybe $400,000 is in the value of the site – no matter what size of house is on it.
