From a single number to the whole deal
A cap rate or a DSCR answers one question. Buying an income property well means answering all of them at once, on numbers you can trust. RVP Underwriter reads the offering memorandum, T-12, and rent roll, normalizes the seller's expenses to what you would actually pay, verifies occupancy against the rent roll, researches your county's property taxes and insurance, and prices three financing structures against your own DSCR and cash-on-cash targets.
