Make the choice based on expected income, what you can find out about the work shifts and environment at chosen tower
I have had military ATC friends for decades and each can tell stories of their favorite tower and their worst....most times the worst gripping was about how some seniority system and autocrat supervisor just made the job miserable by call ins, double shifts, and never getting off some undesirable shift
You must research about schools, property, crime, commuting, taxes...both state, property....some states or counties have a serious cost of living impact depending where you live
Example Texas has no state income tax, and in my county property tax is real reasonable but school tax is high because of Robin Hood laws...one country east of me has a community college... so those citizens get hit for property, then local school and also taxes for the college
So if interested in BUYING property it makes a significant difference if that beautiful 10 acres and house for $145,000 and Lampasas Taxes vs the same similar property one county east for $213,000 but significantly higher taxes....including the one for the college
I mentioned crime above... My county has only 12 or so murders in last 30 years...the next county east has almost that many a month and a LOT of gang activity, home invasions etc....
