I would have to see your home in person to give a proper analysis because every home is different.
  
I offer a free home selling / buying analysis that will cover everything you need to know about the process plus give you estimates on what you'll net along with your costs for the new home.
   
Below are several single story homes with either a pool or space for a pool.
  
I welcome your feedback which will help me find other homes that I didn't include.
