I haven’t personally used them, as my co-investors and I just boot strap it at this point but have considered.

I have started to looking into Memphis, but don't have local boots on the ground their to help me understand the market yet. 

You will find the top markets competition will be high..I see you have lived in CLT but I highly recommend boots in the grounds, too many over analyze and never visit the market or end up going with a turn key provider having no idea where they are investing..Identify neighborhoods in both markets where you find potentials and visit both market to make the best decision.

While some people are saying the Indy and Alabama markets are great, I have an investor selling everything she has there to 1031 into some more properties in the CT market.Purchase price / rent price matters, but having great boots on the ground matters more. 

You really need to know what you're doing and/or have a very trustworthy, experienced person with boots on the ground.

But I would wait for Seattle and other hot markets to stabilize, the city government are morons - for example almost passing 150$/head tax to combat rampant homelessness.

So, considering he is the boots on the ground and found this deal for us, what is his reasonable share of the profit?

They will be my “boots on the ground “ so to speak.

You will waste more time than its even worth putting pics up on gosection8.com, if you don't have boots on the ground helping with tenant placement, and the paperwork will never get processed correctly or will take a much longer time if you don't have a person that knows people in the voucher office.

If I had a tenant with a dog I would make them sign a pet addendum of course, however it is a different scenario because they would own the dog, not me.Not trying to be combative with you, just trying to understand your thought process.
