I'm trying to get the details of the lawsuit to see if there's a chance the suit can come to me, but the landlord is dragging her feet and asking me to give her any support material I may have.

If N is merely claiming $200, better to just pay or offer half and ask him to notify you *before* there is damage.Or pay a lawyer to defend a nuisance suit for damages...

It took a while to get the first property, but I am currently working on an H House (3 bed 1 bath with a basement) in Richland Washington that has a mother in law suite attached to it.

It has suited me well and has happened to me.

That is just me though there’s others on here much better suited to answer this question 

Your State's manufactured housing association is best suited to answer that question, since they can give more color to the federal statues and whatever your state laws say.
