Congratulations on your plans to buy! It's exciting! However, this is information your agent should be providing to you.
What frequently happens is that people are attracted to new home building in an area they like, and curious, so they walk into a model home or contact the number on the sign. When you do that, you are talking only to the agents representing the seller.
Most new home builders recognize buyers who have their own agents, particularly when their first contact includes the agent and the buyer.
In that situation, the builder (and not you) pays the commission to the buyer's agent. And a licensed Texas real estate agent works in YOUR best interests (a fiduciary relationship). And usually a buyer doesn't pay anything to be represented.
I'm guessing you are NOT properly represented.
If you haven't signed a sales contract yet, I'd recommend finding a qualifed Realtor to help you buy your home. And finding a good Realtor would be another good question to ask people you know and trust.
Go to the schools website. You will find all the information you need to make a good decision. I would suggest you go to the school and check in at the office see how responsive, friendly they are.
Lionsgate is a realitively new builder from what I know of. They seemed to have popped up after the big downturn in the market. I've not heard good or bad about them. Best to ask others in the neighborhood.
You're by the airport and probably under a flight path, so you'll probably hear both aircraft noise and highway traffic noise in that location. Schools are not real close from what I remember. Elementary is probably not that far, but middle and High are likely a good distance.
Always always always use a realtor, even when buying a new home. So these are questions among many others to discuss with your realtor, even before you visit the builder for the first time.
What other neighborhoods have you visitied? Which ones interested you?
