A.P.
No realtor recs but wanted to chime in on schools. As another response mentioned...Pine Richland and North Allegheny are much better than Shaler and Seneca if quality of education are important. I can't speak to how they are for special needs families though. I also recommend Hampton. It is an awesome school (#3 in the State!) and it is small and will stay small. The rest of the schools are huge. North Allegheny is awesome for education but is gigantic and Pine Richland (where I live) is supposed to grow by 53% by the time my first grader is in high school.
Heartland Homes are very nice...good choice there.
Good luck to you.
