Since they are SO much under market even a bigger hit might not put you in serious danger of having them move if you have a good relationship with them.  

I don't look for things to complain about or look for an extra few bucks to squeeze out of tenants, when I rent something I actually give them a leasehold interest in the property and allow them quiet enjoyment to use as they like so long as no laws are being broken, are within the terms of the lease and don't pose a dangerous condition that is reasonably dangerous.

stating Pit Bulls are inherently dangerous and also, stopped making it possible for someone to sue a landlord for a tenant's bad Pit/dog.

Just like the fellow I was talking to today that was trying to find that 2% deal , for some it exits for the pro's those that do it full time and have for years.. the new up and comers like Sharad.. they can be there but for mom and pop or first time investor pretty dangerous stuff really.

@Ashley Pittman I think one of the things to consider here, although buying with no money down is exciting and awesome, it's also more dangerous.  

Giving Lockbox codes can be dangerous, it will actually get you a fine here in Nevada As a REALTOR, but I guess as an investor you have no one to report you!!

You don't need their approval.There is no danger in this type of offer but it will get you moving in the right direction if you really want to be involved in RE.

I've heard for years how dangerous and even deadly it can be.

They keep saying how concerned they are that I am breaking the law, that Im playing a dangerous game, and being a straw man to an end buyer.

Then I found @John Fedro website and researched some stories, and that has given me more substance.
