Housing Woes

What does one do? Seriously!

We have a beautiful home, which Bob has done a ton of work to to make it just that. A home! <3>

It's hard to ask someone to walk away from it, but I have. He knows and I know this house just doesn't work for us now. If I am upstairs and having a bad day, my mom literally comes over to take care of me so I don't have to do the stairs. And if I need to be down stairs cooking, Zack has to come down with me so he stays out of trouble. So being a two-story with living and bedrooms upstairs and me having oxygen NO! We've been throwing around the idea over the last year or two about moving into a development in a single story, established house. That's all fine and dandy, but there is nothing worth buying in our area. And to just up and look in a new neighborhood, we not only have to look into schools for Zack, but doctors for me, etc...

These are our three options! PLEASE we are seeking your input.

• Stay in our house and expand. Not sure if this is an option because I don't know if we have enough equity built. In my very own defense. I love my house and the love Bob has put in to it. But so many bad things have happened since we moved in (flood, cancer, pulmo problems, Lucas, etc...) it just doesn't feel right.
  
• Buy an existing single story home, if we can find one that we can both agree on. He thinks everything is over priced, but he's trying to compare homes to what the prices were 10 years ago. He doesn't like to do research.
  
• Buy a piece of land (which we found) and build what we want. I know a good carpenter :)
