I'm having the same difficulty as you.  

Also, you are right about wanting to have a deposit from the tenant, so they have some skin in the game to take better care of your property.

Difficulty Selling Properties to Free Market again, NOT correct. most investors want sec 8 tenants in.

It should also make potential LP's more comfortable knowing you have considerable skin in the game plus the fact you are profiting from the merits of the actual deal at time of sale rather than collecting fees.

Some want to see skin in the game. 

Im looking at 7% however I think a better safe guard for me to have enough skin in the game is to move the sales price higher just in case he decides to pay off the loan earlier.

I rather have little skin in the game, then nothing at all.

As the others have said 1 week is not long enough to begin worrying. 3x rent is industry standard for a reason, if they make less than that there is a good chance they will have difficulty paying rent at some point.

So it's pretty risky to put loans out solely on relationship with no skin in the game.

Some of your midterm rental tenants will still have difficulty believing parking is available (if they are from the cities), but for the most part- not a huge issue.
