Check my website to see if there is anything that you would have interested in looking at:
Second, a Realtor will have access to the MLS, and a lot of properties (for rent, not just for sale) are listed there.
And, third, if all that fails, here's a little trick: Ask the Realtor to run a list of properties that meet your requirements (3 bed, 2 bath, 1800 square feet, in or near Franklin) that either are expired listings or that have been on the market for more than 100 days. Then, have your Realtor approach the owners and see if they'll consider renting their properties. If they're vacant....in the dead of winter....a lot of them will be willing to. That's a market that no one else is tapping, because those properties aren't listed for rent.
Hope that helps.
