Should I sell or rent my home that I over renovated?

[Brian Northrop]

I bought my primary residence in 2010. While living there I renovated 90% of the house, because it was something I enjoyed and thought it would substantially increase my equity. Unfortunately I didn't do my homework and I sunk more money in the house than I can get back out of it if I sell. I have always had an itch to get into real estate investing, so I am considering keeping the house and renting it out when my family and I move to a bigger home this year. We do not need to sell our current house in order to afford our next home. Should we sell or rent our current home?
