My understanding is that these properties have already been foreclosed on with proper notices given and the deeds officially transferred to the county a few months ago.2) Redemption - My understanding based on the state laws the original owner could walk in tomorrow, hand them a pile of cash and get their deed back. 

How is the proper ROI calculated? 

Unless you have a crap ton of properties its fairly easy to just update the numbers once a month by logging in to your banks website and copying over the new principle balance figure. my excel simply shows property address my estimated value, the debt amount and calculates total equity. 

That worth a hundred dollars easy to the right person.However, if you just have an average unit, haven't had much interest and you rent is a hundred dollars more than the market then you will need to drop the price to be competitive.

Very easy.

And the broker can discredit other, more honest brokers by saying those agents who suggest a lower list price just want an easy sale.However, if a Broker gives you a list price that's much higher than other brokers, usually it's a trick.

Taking from your 401k is the easy answer and unreversible.

Even if you fail you'll find that it isn't easy to find a deal and that may help you adjust your thinking about what a deal really is. 

So, if the attic space was converted to a bedroom without the proper permits (to make it a "legal" bedroom and put the finished sq footage on the tax records) then they won't be able to factor that into their values. 

So as long as I'm maintaining a vacancy rate of less than 5% (at $700/month/unit I think that will be easy), I can't imagine that there will be any concern for defaulting on the loan.
