How the renovation funds cap works
Both Fannie HomeStyle and Freddie CHOICERenovation limit the renovation portion to 75% of the as-completed value. On a purchase, the basis is the lesser of (purchase price plus renovation cost) or the as-completed appraised value, so an honest appraisal matters. Manufactured homes are capped at the lesser of $50,000 or 50% of the as-completed value. If your budget runs past the cap, the calculator flags it and shows the most you could finance.
How your maximum loan is set
Your maximum loan is the cost basis times the maximum LTV for your occupancy. The standard conforming maximums run up to 97% on a 1-unit primary residence and step down for multi-unit homes, second homes, and investment properties. The calculator seeds the standard maximum and lets you edit it, because your credit, file, and lender can set a lower limit. The LTV here is an editable estimate, never a guaranteed cap.
Purchase versus refinance
On a purchase, your cash to close is the down payment: acquisition plus renovation, minus the maximum loan. On a refinance, the new loan pays off your current balance and funds the renovation escrow. HomeStyle refinances are limited cash-out only and CHOICERenovation is no-cash-out, so you do not pocket extra cash beyond the renovation funds. Closing costs and any financed mortgage insurance are estimated separately and not included here.
How to use this calculator
Pick purchase or refinance, the program, and your property type. Enter the price or payoff, the estimated as-completed value, and your contractor's renovation bid. Add a contingency cushion if you want one. The result shows your maximum renovation funds, your maximum loan, and your cash to close, and warns you if the budget exceeds the cap. Nothing here is a rate, a quote, or an approval.
