rent vs sell? north of seattle

[Ryan M.]

I;ve been agonizing over the math on  rent vs sell of our primary residence that we plan to leave. Any ideas would be appreciated.  I currently have two rentals doing well in other states and have experience with one flip.  

The property was purchased for 310K, 20% down 3.5%interest mortgage (~240K). Over two years in the house, so no capital gains; it will sell for about 360; . Mortgage and tax/insurance escrow is ~1500 and it will rent for ~2000 so cash flow of 500. It is  near a good school so it should rent with some ease.  So on one side I have my 60k sunk in it plus 40K tax fee on sale or 500 cash flow with ~500 per month pay down on the debt?  Not sure where to go with this one. 

Thanks everyone!
