Obviously 100% seller financing would work best in most cases, (no appraisals/other dealings with banks for less fees and compliance) but are there other structures?

The concepts of practicality and materiality come to mind, but far be it from me to suggest anything short of full technical compliance

It just one of those things where investors are not in compliance and take a risk.I could see a landlord renting a unit and someone gets sick and they get a lawyer and sue.

From a seller's perspective its wise to expect an LOI before going to a certain level of compliance in terms of providing documentation, and most of them think that way.

It's a legislative issue, which therefore means it may very well lack common sense.As I stated in another thread earlier today, neither a license or a permit will ensure that the work will be done well or even in compliance with the law.  

Ensure the tenant is responsible for all compliance with applicable regulations.

While there have been many changes much is the same and yes, it's been awhile.I have some other experience in investigations and compliance that I have omitted from my profile, not really that RE related. :)

I trust what he has to say concerning Dodd-Frank and related regulatory issues, after all compliance is his business. 

My hat is off to every real estate investor out there who takes the same time and care that my team and I take in staying "Above Board" and in compliance with full disclosure when doing short sales.

Your assumptions are logical to me, but being logical does not mean compliance in many tax issues.
