More Kids/Bigger House

Yesterday morning we spent some time in Fort Mill, SC and a little around Charlotte looking at homes to get an idea of what homes cost, location, etc. Right now I'm favoring a DR Horton home. It's a bit expensive but I love it but doubt we could afford it. Here's the floor plan...

The price on that website if more than we were quoted and both of those are probably more than we want to spend. I think I want too much for what the homes have to offer in this area. I only want to move one more time or at least until I'm too old to take care of myself.

I did talk with a buyer's agent yesterday and I think we're going to use her to do some looking for us. Right now these are our requirements...
1. Master bedroom on first
2. Big Kitchen
3. 4 bedrooms (gotta have somewhere to put more future children besides Logan and Madelyn)
4. office/study/bonus room - something extra for all of the Hooker house computers (maybe even two of these rooms so the kids have a playroom)
5. Porch (even if it's small)
6. Dining room
7. Flat yard even if it's tiny (if you've seen our current yard, you'd know why this is a requirement)

We've also asked the buyer's agent to look for neighborhoods with playgrounds and pools. It was so much fun looking yesterday. I actually got turned down for one development. They said I wasn't old enough. As it turned out they were an adult community for over 55.
