Since this requires more money, I have about 10 people committed to put up 100k (1 mil total), to invest in 1 large or several small projects (goal is mostly to build a collection of rental properties).  

The chart below is Denver focused, but it's interesting data. 

Of course, the failure to collect rent or evict may be negligent or a breach of contract.

What fields / data do you want to collect?

If you want more cash now you should collect it from your buyer in the form of the down payment.

Look at it from the other side, if you held the first note and there was not a second note on the property - and a borrower QCD the property overTo someone else - the lender does not have a right to collect all its past due payments ?

I've been pretty good about doing most analysis and communication by email up until a property seems viable enough to walk, but hadn't thought of tracking my computer time to hyper analyze hours spent....probably have burned quite a few figuring out the methods of data collection and analysis.

Here's one data point based on my experience with a SFR home in Harris County (West U).

Also, find out if your city has code violations and eviction data online or otherwise available.
