I'm talking about value related upgrades, like the examples I posted.
Let me ask you this. For existing housing do you adjust for differences in upgrading? Like your subject has a recently renovated kitchen and master bath, but one of your comps doesn't? Do you adjust for that? If so, why? Maybe because those existing houses that have been updated sell for more?
Why would it be any different for new construction where it is clear as day that buyers will pay more for houses with upgrades than those without upgrades? If that's what the buyer's and seller's are doing, why would I report something different?
We don't just "report" the market activity; we ANALYE it.
Typically, buyers pay more for the upgraded houses, whether new or existing/resale. However, the NEW home upgrades from the builder are charged as a line item cost, cash register style, like bringing up items in a store. That is why, a new home contract can be 40-60 pages long - the builder will itemize and line charge for every little thing - an upgraded hardware pull, upgraded carpet insulation, bone color tile choice vs cream color tile, this C level of wiring vs D level - a base model house priced at 360k can close at 500k with all those items added up.
Will the next buyer pay 140 for all that stuff, some of it personal taste choices, other of it not even noticeable, like who cares about level A carpet insulation the builder changed $60000 more for?
Market value opinion is the most probable price on the OPEN market, ( not just the more narrow builder niche new home market. ) so in order to find out what the buyer reaction would be, the appraiser must find recently built similar , perhaps in same subdivon, resales of existing homes listed on MLS.
I love reading the listing comments - the buyer spent 200k on upgrades from the builder - and on resale; a year later, we see with extraction, the resale got back 100k . If it gets back 200k, great, we just provided support. But rote adjusting for cost of builder upgrades can one day catch up with those appraisals -
