I plan on keeping this house as a buy and hold as well as buying several more properties in the future. 

We plan to keep most of our portfolio in Knoxville.

I personally keep it private. 

Do you normally include detailed criteria (as below) or keep the listing criteria generic?  

I have used most of my traditional financing cap with earlier purchases so now I'm using creative financing like seller financing and sub-to purchases to keep growing my portfolio.I'm currently focusing in Tennessee on homes under $500,000.

Keep an eye on properties for sale in your market, what they are selling for, and what features buyers are looking for.

If you plan on using the HELOC as a down payment on another property that you plan on financing, just keep in mind you are increasing the debt on your current property, and paying interest on the HELOC, as well as interest on the new purchase if you finance it 

If you are the only one providing value, there's no business sense in keeping people around that provide no value - at this point, it should be YOUR team. 

Some will believe they can handle the transaction themselves and will either end up under represented or the listing agent will end up doing double duty to keep deals together.

It is certainly a pain trying to keep up on what seems like continual regulation changes.
