So one of the reasons you put rental properties (defined as a dangerous asset) into an LLC is so they cannot penetrate out of that entity and get into some of your other assets such as your cash savings (safe asset). 

I worry about quantitative easing, about artificially low interest rates, and about some potentially dangerous practices that let banks insure deposits and practice sometimes unsustainable lending.

Insurance is driven by so may factors, like age, # pools, location, construction, condition, etc. that IMO it would be dangerous to offer a price based on estimates when it's so easy to get a quote.

The danger in refinancing lies in ignorance.

I can get 100% (100% finance means any under million dollar duplex or Condo BUT hefty mortgage so DANGER if empty and I have to pay mortgage alone!)

Or to see if he was in danger of foreclosure.

Complicated, but definitely do-able -- hence the continuing explosion in EB-5 that shows no sigh of slowing.  

I understand your concern but being a felon doesn't always mean the person would be someone that is a danger.

The auction process can be tricky to navigate and has dangerous pitfalls that could potentially cost you >100% of what you might pay for a property.

The multi family units in my area are either in a very dangerous part of town or are way too expensive to cover the expenses with the rental income.
