We had a tenant blow us into the USPS because a couple of tenants were using a common mailbox at a rural multi. 

I'm too conservative to buy blind but if I did I would estimate repairs for worse case scenario and I would drive by the property, possibly try to take a peak and talk to the neighbors. 5) costs I can think of; closing costs, repairs, holding costs such and taxes.

But above comment is probably right about tragedy of the commons effect on "everyone's laundry area" which can be a cleaning and utility cost issue and even vagrant or misuse issues..

This is very common for out of area owners. 

I made an urgent request to obtain a duplicate key to the common area (note that this key is required to be able to enter my condo unit), and the property manager has not delivered the keys 7 days later, in spite of letting him know this is urgent.

Consider this scenario.

Certain things can happen which revive the redemption period but not all that common in residential transactions.  

@Ashley WolfeI probably wouldn't use an agent for the off market properties unless they are sharp with common sense and can negotiate.  

Hey Jeff,Your experience seems pretty common with the new note investors I've met in the past year or two.

As for a trust, and ALL of these scenarios you should seek counsel from someone that knows the laws in your state, regarding real estate, taxes, etc.
