This couple built their own container home in Denver and had it appraised at +$700k in 2016 with roughly $430k in construction. http://www.denverpost.com/2016/04/01/couple-builds...This is fairly consistent with market studies on these types of homes that I've seen. 

Study your states landlord tenant laws If you file the judge would probably issue a writ saying she has to be out in xxx days, the money owed for back rent and fees are on that paperwork, the cause for eviction action is past due rent, failure on her part to pay, so that's why you want her to leave... you'd still have to take her to court in small claims to collect.. the filing is so you regain the right to your property and is forced to vacate. 

The education will prove valuable.  

I am barley scratching the surface starting to study this stuff currently still out of work I relocated to Fort Wayne, IN. 

The education and network will prove to be extremely valuable.
