The skilled living center that is being built should not affect the property values in Creekside Estates (or Sage Creek, Maxwell Creek, or any of the other surrounding neighborhoods). As you may have noticed, there is a well-maintained mobile home community near this area which doesn't affect the neighborhood values either. Currently the Creekside Estates neighborhood is still building strong (the entire neighborhood is Ryland Homes). Residents there can enjoy the 36 acres of parks, hike/bike trails, and community pool.
If you are planning to purchase a new home in that neighborhood, you will be looking at lots on the far end of the neighborhood from McCreary Road, which is where the skilled living center will be located. The living center has taken measures to ensure that their building blends well with the surrounding areas.
As a buyer, it is in your best interest to hire a Realtor to work on your behalf. There is no cost to you as a buyer for these services, and most realtors can help you with pre-owned homes as well as new construction homes.
I hope this answers your questions, but if you need anything else please feel free to contact me anytime.

It shouldn't negatively affect it at all unless it changes the zoning of the area. The zoning is what's important. If it's a well maintained area, it will be fine. If it's not maintained well, it'll obviously drive property values down. Wylie is a small community and typically these centers are put near a place where people will live who need to be by their parents or loved ones, but they can not care for them in the home. You probably don't want a lot that backs right up to it.
