The one thing that has really saved our bacon is having a very in depth lease.

There are a lot of threads on this topic (that go into a lot more depth)...They show up in the search bar if you search for "90 day rule" (if you searched, I'm guessing "91" was the reason you didn't find them)...

If you share more in depth info about what sort of home in what sort of area, you will be able to find renovators, realtors and pm companies to help you directly invest and manage your investments.

Most county assessors are now available on line and most are free (at least in KC), but you will spend  a tremendous amount of time trying to manipulate the data into usable information that will help you find good deals.  

This kind of interpretation comes from a depth of knowledge of the tax code and years of experience working with IRA plans and related court cases, and piecing together all the variables and interrelated components that impact such structures.This is, arguably, a conservative interpretation.  

@Raj Kumargo the council route first you will prob have better luck going friendly than hostile but if that doesn't work reach out and I can talk in depth about our experiences. 

@Brad Smith, any clue the depth of the grade beams... that'll give you an indication of how much deeper you'll have to dig (and just in case... make sure your trench isn't inline with a pier).And, if in the future you don't want to dig a trench again, consider renting a mole from the local rental yard.  

The width seems to work with most units I've researched, but the not the depth (I've found some slightly under 27.5", but I still have to account for the exhaust pipe of the dryer).

I have to give credit to BP's "Ultimate Beginners Guide" for really getting me acclimated to the Real Estate Investing world and getting some quick general knowledge on the basics with tons of links to more in depth guides, blogs, articles, etc.  

Did the borrower manipulate the terms to an unfair advantage?
