Hi there...glad to hear you'll be giving H-ville a go.
Our family transferred her in October, having never laid eyes on the place...my best advice is to come and spend a weekend or two in Hendersonville...really drive around and get a lay of the land. We are still exploring and finding new areas which is why we decided to rent first and then buy later if we were still in love.
As for finding a rental, I recommend finding a realtor that handles rentals because I found the internet search quite disappointing...
