How do I find out the value of a commercial property if I want to sell it by owner?

It has 3500 sq. ft. and has 5 rental units (2 apartments @ $750.00 each per mo.) 2 commercial spaces @ $500.00 each per mo. and one commercial space @ $800.00 per mo.--At $3,300 rental income per mo.(using the income approach) What is the value?

i think you need to go to your courthouse and ask them. they have all that stuff valued

I would have the property appraised by an independant appraisal company.

Get an appraisal. Put it on the market with an asking price that is a little more than the appraised value and see what happens. Be prepared to come down if nothing happens. You can always sell real estate and people who can't find a buyer are simply asking for more money than anybody's going to give them.
