@Daniel Lioz I certainly think it would help your appraisal, and somewhat depends on the quality of the lease/tenant for the eyes of the bank and appraiser.I think you're somewhat asking if you can get in the purchase with no money-down because of the value add, no probably not, because the bank will want to see skin in the game.

All I had to do at that point was plug them into my existing system.You need thick skin in this business but I think most of the money from it is made by creating a system that manages your own portfolio well, not other people's portfolios, especially in multifamily. 

For example, let's say Mary Smith fills out an application to rent my property and puts down her boyfriend, Jim, as her "landlord", who has been previously briefed to give her a glowing recommendation.

Sorry to be the bearer of a less than ideal response, but it's not usually that simple if you are going to have no skin in the game. 

They have more skin in the game then you do.Make sure you get clear title.

I’m not super comfortable with tenants having no skin in the game to conserve.

Otherwise, you will need to put skin in the game. 3% for FHA.

Tons of ways to skin the cat. 

And I've noticed more and more gurus are being super sneaky about hiding the names and locations of the glowing testimonials to make sure you can't verify their claims.

You have no skin in the game, go home."
