To sell or not to sell?

[Ivan Martinez]

Hello, i currently own a home and want to move out, I have a few options but not sure if any are better than the other. home currently has some equity. 

1. sell and buy a cheaper home. 

2. Sell home and move to apartment and invest profit in stocks etc. 

3. refinance home and rent it and apply for a second mortgage to buy another house.. would definitely appreciate any feed back.
