Max Bid Formula

def max_bid(arv, repairs):
    cushion = min(25000, 0.15 * arv)
    return (arv * 0.70) - repairs - 10000 - cushion

def recommendation(bid, judgment):
    ratio = bid / judgment
    if ratio >= 0.75: return "BID"
    if ratio >= 0.60: return "REVIEW"
    return "SKIP"

Multi-County Scale

• Current: 3 counties (Brevard)
• Q1 2026 target: 67 FL counties
• Scale threshold: Render.com at 50+ counties
• Table: multi_county_auctions (partitioned by county)
• Volume: 1K–2K auctions/day at full scale

Lien Priority Critical Rule

When plaintiff is an HOA → the senior mortgage survives the foreclosure. This means buyer at auction takes property subject to the mortgage. NEVER mark HOA-plaintiff properties as BID without lien analysis.

-- Flag HOA plaintiff properties needing review
SELECT id, case_number, plaintiff, recommendation
FROM historical_auctions
WHERE plaintiff ILIKE '%HOA%' OR plaintiff ILIKE '%Association%'
AND recommendation = 'BID'
