Vacant land bought in Charleston Tri-County → construction loans in 9-15 months.
Every other broker tool optimizes for “transact in the next 90 days.” This is the inverse — find lot owners BEFORE they need a lender, build the relationship over 12 months, become the only call when the construction-loan question appears. NAHB lot-buyer data: 60-70% of vacant-land purchasers break ground within 9-15 months. The 6-9mo and 9-12mo buckets are the peak.

NAHB lot-buyer behavior research: 60-70% of residential-lot purchasers break ground within 9-15 months of acquisition. In master-planned subdivisions with HOA-mandated build clocks, the rate climbs to 80%+ because failure to build within the clock triggers fines or forfeiture.
