This is why I was asking how lenders (I should have said appraisers) value these properties if they aren't performing.

Knowing the long term gain in rentals will out perform flips.  

Usually when those conversions happened utilities were not split properly especially since no building permit or proper inspections of the quality of the conversion work performed.

I would highly recommend @Rob Drum in who's a high-performing agent in the greater Birmingham, Alabama area.

Machine learning is not a means by which to evaluate or perform analysis, be it financial or other.   

Anyone have recommendations for gathering general economic data, things like stock performance in past years, job growth in different places, REIT or syndication performance.

You can be sued for specific performance, or you could be sued for damages if the eventual sales price of the property is lower than your contract price. 

In the medium to long term I think it will benefit note investors by increasing the supply of non-performing notes.

Those of us holding re-performing and sub-performing loans will be at risk, again not the banks.This time, the Federal Reserve and the federal government are rolling everything that they've got to make the transition from crisis to recession as smooth as it can.

Real estate is considered an essential service like banking and agents as well as appraisers and inspectors are permitted to continue to perform their jobs, of course with extreme care and caution to prevent infections.
