The value-add playbook everyone knows ends with a refinance: buy it right, fix it, re-lease it, then refinance the improved income and pull capital back out. When it works, the refi transforms the deal's returns, because capital returned in year three changes the arithmetic of everything after it. Which is exactly why it deserves suspicion in the model: on many deals, the projected returns do not merely benefit from the refi. They require it, and a required future event on terms you do not control is a risk wearing the costume of a plan.
Underwrite the refi as an event with three independent ways to fail. The rate at refi is the one everyone learned recently: the loan that replaces yours will be priced in a market years away, and a model that assumes tomorrow's rates equal today's has made a forecast while pretending not to. The value at refi is the second: the new loan sizes against an appraisal, the appraisal capitalizes your new NOI at whatever cap rates then prevail, and cap expansion between now and then shrinks proceeds even if you executed the plan perfectly. Coverage at refi is the third and the quietest: the new lender sizes against your in-place income at their coverage floor, so the rent roll has to have actually arrived where the pro forma said it would, on schedule, in cash.
When the proceeds fall short, the result has a name worth dreading: trapped equity. The plan said the refi returns most of the capital; the market says it returns half; the difference stays in the deal, the investors' timeline stretches, and every return metric that depended on early capital return quietly deflates. Nobody lost money yet. Everybody lost the deal they underwrote.
The modeling discipline follows from the failure modes. Give the refi its own assumption set, rate, coverage floor, and value basis, and stress each one separately and together, the same way you stress rent growth and exit caps. Find the refi break: the combination of rate and value at which proceeds no longer clear the existing debt plus the promised return of capital. Then look hard at any deal whose returns collapse without the refi, because that deal is a bet on a future credit market, and it should be priced like one, not like a leasing plan.
PropCalc™ models the refinance as a first-class event in the hold, with its own terms, wired through the debt stack, the distributions, and the waterfall, so the with-refi and without-refi versions of the deal sit side by side instead of the second one living in nobody's spreadsheet. That comparison is the honest one to show an investor. The refi is a wonderful outcome. The underwriting question is what you own if it does not come.
