The Back-Solver
Every deal is four numbers — rent, build cost, land price, and the yield you need. Lock the three you know and this solves the fourth: the most you can pay for land, the build cost you have to hit, or the rent the market must prove. Run it back and forth until the puzzle fits.
Solve for
Site coverage = building SF ÷ land SF. Small-bay sites typically land at 25–35% once aisles, parking, and detention take their share (illustrative). Yards products run lower and earn separate yard rent — model those in the underwriting tool.
The trade-off table
Every row is a version of your deal that hits the target yield — showing how rent, build cost, and land price trade against each other.
