I’m mainly concerned about safety and liability for the tenant.

Real estate investing is a pretty forgiving world and the average person can still make money even with some pretty big mistakes.Buckle in, keep your arms and legs in at all times, and enjoy the ride!

Safety - Learn about Crime Prevention Through Environmental Design (CPTED) and employ the concepts at your property.

Scope out neighborhoods within your target price range and research rents, schools, safety, etc. anything that is relevant to you3.

I would -- in this case safety should be fairly cost-effective. 

They are concerned about their safety and don't really know what to expect when they enter so they prepare for the worst as I am sure you can imagine.

One of my lender's has a good 10-1 ARM product that can get you a lower rate.

You don't need a degree to succeed but having it would be a safety net.

They are looking at specific things, particularly safety issues.  

Lol please explain a logical scenario where someone who was fully informed of the value of their home would sell it in an arms length transaction where they are still on the hook for the mortgage for $77,000 less than what it was worth...............I'll wait.
