If you get discouraged easily or have soft skin and take doors slammed in your face personally, I would suggest another option.I am not the type to door knock, although I have done it.

I have enough skin in the game that I know I will lose my money if I don't follow through on our agreement = I am motivated.As a lendor - "CYA" would be my policy.

It's easy for me to say this since I don't have any skin in the game here, but I have seen enough inherited tenants to know (at least for me) it seldom works out long-term. 

My skin is crawling just from seeing it.

They have no skin in the game.

@Danny Webber thank you I appreciate the truth and if I need to take more time building my cash pile to have more skin in the game by maybe wholesaling or just working than that's fine.

Lenders want you as an owner to have "Skin in the game".

So you now need more skin in the game with guarantees of the lease,rental increases,etc. as it affects a larger portion of the building now.No legal advice given. 

Back of the napkin math may work, but if I was the seller you do not have enough skin in the game to make it work.

You see, many a solider is talked into buying with a VA loan because entry into a mortgage is easy and you have no skin in the game.
