Since you're the only guarantor of the mortgage, you have more skin in the game becuase you stand to lose more than the principal in a default scenario.

Are they wanting some skin in the game from the buyer?

Banks are gonna want a real low LTV and for you to have a lotta skin in the game.

$450 cash flow with no skin in the game.

That means we agree that we have equal value or skin in game.

Noise complaints, parking issues, claims by some of paying lower rents just to get under the skin of someone they don't like or claims of special treatment or petty complaints about neighbors.

Look for those that Have skin in the game do not fall into the trap of working with West coast marketing agents that own nothing and only make a commission selling you some dog in the mid west  or rust belt.I wrote an e book on how to deal with TK companies and out of state investing if you e mail me I will send you a copy its free and non biased as I have nothing to sell .Anytime you get on BP and say you have 250k to invest you will be hounded... tread carefully and in my opinion only invest with those that have deep track records as @Brian Burke mentioned or those with deep experience as @Joel Owens mentioned  as for SFR's @Sharad M. has a lot of experience and you can buy direct from him not through west coast middlemen that will take a huge cut off the top.

He will be putting skin in the game as well.
