How prices were stored
- Exact dollars when the site showed them (CastleRock, Brohn, DRB, inventory).
- DR Horton floor plans are advertised as bands ("Starting in the $271s"). Stored as
$X990for sorting (e.g. $271s → $270,990 community from-price; plan Anderson $271s → $270,990 because community "From $270,990" is the Anderson). Other DRH plans use$band990(Abbot $291s → $291,990). - Brohn 1665 Casetta card listed 1,662 sqft; name stays 1665.
- Brohn 1830 Casetta card listed 1,828 sqft.
- 2051 Casetta QMI at 180 Lennox is listed 4 bed / 2.5 bath while the base plan card is 3 bed / 2 bath — inventory uses the QMI card, plan uses the base card.
Incentive valuation (Brian 2026-08-29) — CMA showcase
Use for every competitor unless overridden:
- Advertised special note rate (CastleRock 5.25% FHA/VA, DRH 4.99% after 2/1 years) → 5% of list price
- 2/1 buydown (temporary years) → ~2% of list (typical cost; ignore builder $ examples)
- Closing costs covered (DRH: up to 2%) → 2% of list
- Flex cash → stack the stated $ (or $0 if the promo does not list it)
- Owner's title (OTP) when the builder covers it = TDI basic premium, rates effective March 1, 2026
OTP for $100,001–$1,000,000:
OTP = round((price − 100,000) × 0.00494) + 780
