You need a good mortgage broker to navigate the correct waters for you to swim in.Stephanie 

I found out that there is a detached in-law suite in the property that I'm looking for, which fits for rent.

Added value by:- creating master suite (adding a bathroom to floor plan)- adding a living room/family room- new roof- solar-tube lights- renovating bathroom- refinish and stain hardwood floors- building a deck- building a masonry entrance stoop What made you interested in investing in this type of deal?

I realize this is probably better suited to ask a lawyer and that these are very difficult and uncertain times.

Look at putting an airbnb in an inlaw suite or something like that.

I'd also open up your options to homes with in-law suites that you can section off into another unit.

First rule of suing, sue everyone so you will definingly be named in the suit especially since you know about it. 

If this happened in Indiana, I'd pursue a small claims suit because they are quicker and there's less hassle.

I'm trying to get creative with how to add an ADU / Mother-In-Law suite.

I don't believe you can just go back to an addendum that suits your needs.
