When we moved out of Jax in 2010 we also put our townhouse up for rent instead of selling. I initially listed it myself but after a few days someone from Rebate Rentals in Jax called and said they could get me more rent. They ended up getting us close to $300 more a month than what I had listed it for, which more than paid for their fee which I think was around $800. We used them for a few years until we sold it in 2013. They always found us good tenants and show you all of the credit and background checks. We even rented it to a former Jaguar linebacker for one year.
Best part was the person there offered to manage it on the side for us for only $75/month. She had her own handymen that did any repairs which was very helpful since we lived 4 hours away. No idea if she is still with Rebate Rentals or if she is still around Jax but the email I had previously used for her was suzannerentsandsellsjax at gmail.com
