How to Build a Real Estate Development Model
A development model converts land, construction, timing, financing and exit assumptions into monthly cash flow and investor returns.
What the analysis measures
Start with the complete sources and uses. Separate land, acquisition costs, hard costs, professional fees, contingency, finance and selling costs so no cost is hidden inside another line.
Calculation framework
Build the monthly programme before calculating returns. Phase construction, debt draws, interest, lease-up or sales and the exit in the periods when cash actually moves.
Underwriting review
Reconcile opening debt plus draws less repayments to closing debt. Confirm total project cost, peak equity, sold units or occupied space and final debt independently.
How to use the result
Read development profit, yield on cost, IRR, equity multiple and downside funding together. A high IRR does not compensate for an unfinanceable peak cash requirement.
