You will likely need to pull out and cap the bathroom plumbing if the bathroom was not approved and remove the stove since the city is already on notice of it.

Sewer issues in Chicago are very common which is why I ALWAYS recommend / almost require my clients to get them done + if there's trees in front or in the back of a property, there will almost always be plumbing issues + needed rodding. 

Water leaks, problems under the trailer ie insulation falling, a tub cracking, a new roof, frozen/cracked pipes (usually in January- and plumbing companies simply will not respond to mobile homes), rotting siding, bad exterior doors etc. 

You might want to start investigating methods for locating off-market opportunities that appeal to you.

I have used several methods that have been quite fruitful over many years. 

Realtors listing is a great way to market it, Facebook is also an underutilized method.

When looking for a property to purchase, make sure you take this into account. 2) The BRRRR method is really hard to do in Bing, especially in student areas.

The reason for this is because most mechanicals electric plumbing are more in line with today's code, and a lot of these properties typically need more cosmetic type of rehab.

I can fix almost anything and have experience with electrical, plumbing, flooring, roofing, siding, drywall, etc.  

Same BRRR method we use for a typical LTR, but better equity, ROI and use( gift it, use it and better tax write offs)
