Where do you find research on your market

[John Morgan]

I am in the beginning stages of starting my investment company and am writing sort of a business plan. I want to include a section that defines my market and shows how the Knoxville Tennessee market is doing. I am looking for information on the amount of homes being rented vs bought, what the temperature of the market is, and any other types of data that I might be able to include on a letter to give to a private lender to show what the market in Knoxville is like. 

Any ideas where to get this information? Should I just look at the main sites like zillow and truilia or are there different ways to research this? Also any other information to help a new beginner looking to purchase buy and holds would be great. Thanks

John
