Part 1 of 4

Why a seller cares

Operating expenses are what it costs to run the rental, before the mortgage, and buyers compare your figure to their own rule of thumb. A seller's understated expenses are the first thing a buyer's underwriting corrects.

Part 2 of 4

A simple example

Your duplex's expenses last year: $3,400 taxes, $1,600 insurance, $2,100 repairs, $1,300 management, $1,250 reserves. About $9,650.

Operating expenses are the cost of the building, not the cost of the loan.

Part 3 of 4

What people get wrong

That a low expense figure makes the building look better. Buyers underwrite their own, and a seller's number that is too low reads as a seller who does not know.
