Need some advice on Buying vs Selling my home.

[Jeffrey Walther]

My family currently lives in utah county and my mortgage is 802.57 a month with taxes and escrow at a 3.75%.  We owe about 133k on our home and we are looking into getting into a bigger house/ better neighborhood. We aren't planning on moving for at least a year, but we just want to gather as much information as possible. On zillow our house is estimated at 250k and rent is 1200 a month. 

My goal is to get a good amount of passive income so we can be financially free and I figured that renting it out would be a good way to do that. But after looking at it, we could sell our house and put a good amount of money as a down payment and still have 10-20k left over to invest in other opportunities. Any advice would be greatly appreciated.
