Tim,
What is your stance (or the GSE's) on using pre-sale's or built-to-suit homes? I have alway's wondered about this.
I am speaking of a PUD development which is being built by a national builder in a typical tract home project. The lots are all owned by the national builder and the buyer goes into the model home or design center and chooses the selections and upgrades.
Some developments are selling so well that no active or closed sales are in the MLS.
Other builders list the sales in the MLS as "for comps only" or the good sales

for the appraisers to use. They have "fake" DOM as most of the time the homes were already under contract when the builder put it in the MLS.
So I get where Marion is coming from. What is the DOM for these sales? Are pre-sales or built-to-suit homes market exposed sales? How do you derive market based adjustments for pre-sale homes? Download the builder cost sheet and make dollar for dollar adjustments?
FWIW, I avoid new construction appraisals..... it is a scam and a waste of time....worthless. My family is (was a mid-sized builder, we sold our residential building business for 90 million several months back) so I know what goes on.
I find it funny and ridiculous that a appraiser uses pre-sale homes as comparables and makes adjustments for quality or differences in upgrades....yeah...market based adjustments???? From what market...the builders cost sheet LOL!!! And then in the MLS the builder has one spec home that sold for 5-10% under what pre-sales are selling for and was fully finished and full exposed to the market.
Builders either own their on mortgage business or have their preferred lenders. Builders, real estate agents and the mortgage companies (and now AMC's) are all in bed together. From my experience, the same olde appraisers and larger appraisal firms gets most of the new construction work and sets the market for when the buyer does not use the builders preferred lender. Builders offering incentives for the buyer to use their preferred lender..... Trust me, if you kill a deal with a builder, you will not work for the builders preferred lender. To many bonuses and business deals for the lender to lose for some honest appraiser to screw up.
