When to sell a rental property?

[Tony Mayo]

I have a 2 family property that I purchased 2 years ago for $275k. It is in a commercial area AND the company nEXT door would like to buy it for about $450k. MY RENTAL RATE IS ABOUT 1.5% PER MONTH... TO DATE I HAVE ALWAYS BOUGHT AND HELD FOR THE CASH FLOWS SO THIS IS MY FIRST SALE FOR CASHING OUT FOR EQUITY. SO I AM TRYING TO GET A BETTER CONCEPTUAL UNDERSTANDING IF I SHOULD COnTINUE TO HOLD OR aM I CRAZY ANF SHOULD I CASH OUT?
