Part 1 of 4

Why a seller cares

Cash flow is what an investor expects to have left each month after every expense and the mortgage, and it is the number their offer on your rental has to make work. A negative cash flow at your asking price means no investor offer.

Part 2 of 4

A simple example

Your rental brings $1,700 a month. Taxes, insurance, maintenance and management take $600, and the investor's mortgage at your price would be $1,200.

Cash flow: a simple example
At the price offeredThe investor's monthly cash flow
$240,000About negative $100; no offer
$210,000About $50; a thin offer
$190,000About $150; the offer they make

The investor's offer is the price at which your rent still leaves them something.

Part 3 of 4

What people get wrong

That a rented house is worth more because it has income. It is worth what the income supports, which can be less than an empty one.
