How it works
The turnkey-versus-value-add decision is a trade between today's cash flow and tomorrow's forced equity. A turnkey purchase hands over a rented, renovated property: income starts at closing, management is simple, and the price reflects that convenience. A value-add purchase buys dated paper cheaply, injects renovation capital and several dark months of carrying costs — loan interest, taxes, insurance, utilities on an unrented unit — then exits with higher rent and typically an appraisal above total cost. Both paths deserve the same yardstick: year-one cash-on-cash return on every dollar actually deployed. This calculator applies identical underwriting to each — 25% down, 7% thirty-year financing, a 35% operating ratio, 3% closing costs — then adds the pieces only value-add carries: the rehab budget itself and month-by-month holding costs across the renovation timeline. The primary output is the gap between the two returns in points, alongside the extra cash the value-add path demands and how many months of rent premium repay it. When the gap favors value-add and the payback runs short, forced appreciation is being bought at a discount; when turnkey wins, the discount was already priced in.Formula
CoC(path) = (rent×12×65% − debt service) ÷ cash invested | VA invested = down + closing + rehab + carry(months × interest+holding)
Tips
- Get three contractor bids before trusting any rehab budget — overruns eat the gap fast.
- Carry costs are real cash: interest accrues during rehab whether units earn or not.
- Verify the after-rent with property managers, not renovation optimism.
- Value-add wins compound when you repeat it; one project rarely justifies the learning curve.
- Compare identical neighborhoods — cross-town comparisons measure markets, not strategy.
