What this calculator estimates
Estimate refinance proceeds, cash left in a BRRRR deal, rental NOI, monthly cash flow and DSCR.
How to use it
Enter Purchase price ($); Rehab cost ($); Closing and holding costs ($); After-repair value ($); Refinance loan-to-value (%); Refinance interest rate (%); Refinance term (months); Monthly gross rent ($); Vacancy allowance (%); Monthly operating expenses excluding debt ($). Select Calculate to update the results.
How the calculation works
Total project basis is compared with refinance proceeds based on ARV and LTV. Rent after vacancy and operating expenses produces NOI; refinance debt service is then subtracted.
