Use when someone gives an address and an asking price and asks whether it is a good deal or what to offer. Runs RBSHome's offer calculator on a Dallas or Collin County, Texas parcel: target resale (default: the CAD land-value median of comparable lots, or your resale_price) minus flag discounts (floodplain, no frontage, delinquent taxes), closing, holding and the buyer's margin gives a maximum allowable offer (MAO), an opening offer, the line-by-line math and how far the asking price is above or below the MAO. All assumptions can be overridden. Not an appraisal or advice. Counts as a property lookup. Read-only.
The seller's asking price in dollars, e.g. 85000
Street address in Dallas or Collin County, Texas, e.g. '1234 Elm St, Plano TX 75023'
RBSHome lead ID like 'Collin:2771234', when already known (skips the address lookup)
Apply the delinquent-tax discount (default 10%). Default: on when the parcel is a tax-delinquent lead.
Apply the floodplain discount (default 20%)
Buyer margin as % of adjusted resale. Default 20.
Closing costs as % of adjusted resale. Default 3.
Apply the no-road-frontage discount (default 30%)
Opening offer = MAO less this %. Default 15.
Your target resale price. Default: the CAD land-value median of comparable lots (estimate_lot_value mid).
Flat assignment fee instead of margin_pct, e.g. 10000
Months held. Default 3.
Holding cost per month in dollars. Default 150.

Up to 25 leads; rows count toward the daily row limit. Returns no phone numbers or emails. Read-only.
