Try rentometer.com which will give you an indication of the rental rate for month-to-month. Another resource is VRBO ( vacation rental by owner) which you can use to compare your rental with what is available.
You might want to consider a cleaning company, deposits and insurance.
Feel free to contact me directly if you want the rental rundown in that area. All areas are pretty hot right now, rental demand is way up.

Sometimes I find that our local lender can come up with that info as well.
If you'd like his contact info, contact me via email and I'll send it back to you ...
