cal_valuation
Run a comparable-sales valuation on a subject property using provided comps to determine market value, price fairness, and list-price rebuttal.
Instructions
ValueGuard: run a comparable-sales valuation on a subject property and return a list-price rebuttal. Given the subject (address, list price, square footage) and at least 4 comparable listings, returns the indicated market value with a floor/ceiling range, a verdict (overpriced / at market / underpriced), a confidence level, the percent the list price sits above or below market, and the comps used. Use this for "is this list price fair", "what is this home worth", appraisal-gap or list-price-rebuttal questions. The caller must supply the comparable listings; this tool does not fetch comps.
