IN MY MARKET there are very few spec homes for tract builders so the sales are usually where the buyers go to a model, select model which will usually determine which lot, and the options wanted. Time from contract to completion is usually 3 to 5 months depending on the time of the year.
That sounds more like "cost", or "market price", not market value.
HUD:
MARKET VALUE AND MARKET PRICE. A distinction is made between market value as defined above and market price. Market price refers to the amounts that buyers actually pay. Market value refers to the probable prices properties will bring in a competitive open market.
DISTINCTION BETWEEN COST AND MARKET VALUE. A distinction is also made between cost and market value. Value depends on the extent of utility in the future, while cost depends upon outlays for land, labor, and materials which depend upon conditions that do not necessarily deal with factors which create value.
-If one uses these types of sales, how do you make market based adjustments? Or do you make adjustments on a mechanical scale, cost for cost? If a buyer goes in a chooses $30,000 in upgrades, and you use this sale as one of your comparables, the only way to adjust is for dollar for dollar, on a mechanical scale. Unfinished attic $11,000. Market value $11,000? I don't think so.
-Why even order an appraisal? Cost equals value. If the buyer went in and chose the lot, chose the model and chose the $30,000 in upgrades, that market value. m2: (no, the $30,000 in upgrades have not been exposed to the market, that's market price.. see above). It's no different than a custom home builder taking buyer to the Depot and having a shopping spree).
In my opinion, this methodology leads to new homes being over valued.
This down market has confirmed this.
When the market started softening in late 2008, a tract home project with one builder caught my attention.
They would always list home in the MLS for "comps only", and when the home was finished, marked it a sold in the MLS. The buyers went to the on-site agent, picked the lot, picked the model and picked the upgrades.
This was a fairly large project, and re-sales were starting to come to the market. As prices were starting to decline, I started noticing a distinct price difference between builder sales that were not exposed to the market and normal re-sales. The difference was about 15-20%.
Why?
The meeting of the minds were about 6-9 months prior to what the MLS closed date was. The meeting of the minds took place under totally different market conditions, even though it closed escrow a month ago. The only thing the appraiser cares about is that it closed 9/2009.
Cost doesn't equal value. The market wasn't paying for 100% of the upgrades. I sure felt bad for those buyers, and for the bank who lost big time...
When the builder did build a spec home, it always sold below what the other "non-adequately exposed" homes sold for.
