My agents are all taught to be the source of the source.

We were, but he missed 2 things, my wife’s income and the taxes I paid.

In the past, I've found them to be a good source of information to get insight on the market. 

I love income properties so my first inclination is to keep it.

It is interesting to see in the Smokies 8 to 12 bedroom homes are not getting that much more income than 4 to 5 bedroom BUT has 4 to 5 bedroom been overbuilt as they represent majority of the building permits?

Do they plan on getting income? 

I agree with Jordan, your agent is the best in coming up with comps and ARV. 

You have to figure out how to deal with them or say goodbye to the income.

I do like to start with open communication but if a tenant does not appear to be interested in coming up with solutions I recommend using an attorney right away. 

Combine that with SS income (maybe?)
