Plano, Allen, McKinney, Frisco, Murphy, Lucas, and Wylie are all good places to live. It depends where in Plano he will be working. Plano covers a large geographic area and it can take 45 minutes in rush hour to get from one side to the other. Crime is pretty low in all those areas, but property taxes are stupid high. Texas doesn’t have an income tax but they get you on the property tax.
Nearby airports are Rockwall (F46), AeroCounty (T31), McKinney (TKI), and Addison (ADS). Unfortunately hangar wait times and rent are crazy in the Dallas area.
Let me know if you need anything else.
