<prompt> Human: I have a home that I have been renting out for a few years now. Ive been making money on top of paying the mortgage and extra to the principle each month. Its recently come to my attention that the demand for housing in that area has blown up and the value of my home has gone up. I havent checked specifically how much but I vaguely remember remember seeing once that the value was up 20k for what I purchased it for. If the value is going up substantially, should I sell the home or keep renting it out. Ive been pretty satisfied with renting it up to this point.  <response>: 20k is not a lot of money when you factor in closing costs.
