Finding Market Value

[Tyler Kesling]

Still new here- I know I can find the cap rate by dividing the NOI by the market value but what's the most reliable way of finding the market value? Example, say I have a 10 unit property, $800 per month. 10u x $800 x 12 months x .9 occupancy x .5 expenses = $43,200 NOI. How do I know what cap rate to use to find out what the market value of the property is?
