How this calculator works
Cash-out refinances are based on today’s value. Renovation refinances use the as-completed value, with the budget held in escrow and paid in draws.
Construction-to-permanent loans are usually interest-only on drawn funds during the build. Bridge-to-DSCR scenarios compare stabilized rent with the long-term payment.
Frequently asked questions
Which scenario should I choose?
Use cash-out if you want funds now based on current value; as-completed renovation if value depends on the work; construction-to-permanent for ground-up builds; bridge-to-DSCR to exit a hard money loan.
Why is the build-phase payment interest-only?
During construction, funds are drawn in stages and you typically pay interest only on the amount drawn so far.
Is this a rate quote?
No. You enter the rate. Owner-occupied refinances are handled by a licensed mortgage partner, who provides any actual terms.
Does it account for closing costs?
Check the inputs shown. Appraisal, title, inspection and lender fees can change the cash you need.
