Lakeisha,
I know the turmoils of finding *the* perfect home. We looked for what seemed like eternity before we finally settled on Horizon homes.
We even considered moving to Heartland, but the HOA wouldn't allow my husband work truck to be parked there while he was on call. Be sure to check out the HOA of wherever you choose to move to. They can have some pretty quirky rules!
I believe that kiddos who live in Heartland go to Crandall schools. You might want to check out the school district since your little girl will soon be going to school! I have heard from people who send their kids to Forney ISD that Forney is a nightmare. So, whatever you do, check it out! :)
I don't really have any firm answers to your questions. I did like the DR Horton homes. They just didn't have any floor plans that would work for our family. (We homeschool, and have specific needs.) For some time in looking for our new home, I would compare all the energy efficiency ratings, the foundations, windows, insulation used etc, etc, etc.
THEN! One day, I had an epiphany! It doesn't really matter all that much because all of the homes in the area are really all built pretty much the same! We then just started looking for a house that we all felt "at home" in. Finally! We were so thrilled to have found what we wanted! AND not to worry about all the other stuff. Just make sure they offer a good warranty. I forget what they offer.
Heartland does seem like a nice neighborhood though. I love the little "bus stop" signs they have up throughout the neighborhood. And, even though we are not moving there, I am excited to see what retail they build there as well.
When you have your house started... be prepared to be amazed! ESPECIALLY if you go out there once a week only. There will be drastic changes up until the house is almost done. It is amazing how fast it goes up! The foundation is the slowest part. (That is a good thing!) We went out there one day, and the bottom floor was framed out, and the stairs were half way done. For some reason, we had to go out there the next day. It was before 12 noon, and the second story and roof was already done! Amazing.
I could talk about this forever, so I will stop. Good luck in making your final decision. It is a fun process.
