Added a bedroom and bathroom.

So could you take out the $50 you need in a term loan and also open a LOC large enough to cover any issues that arise?

"South Minneapolis" is such a broad term - there might be as many as 25 different neighborhoods ranging from A-D class, each with their own pros and cons.

Same for electrical.....replacing an old GFCI is fine, bit if you're adding more outlets or especially running a new circuit, you'll technically need to get a permit and have it inspected.Now does everyone do this?

Helping others and adding value should be at the top of their list, not making another dollar!

I hope you made it convenient for yourself.Your loan documents should (or better) contain a due-on-sale clause.

Several large developers have built beautiful high end condo feel student apartments super close to campus which initially depressed rents in houses.

Also confirm that county maintenance liens are added to the tax debt.Fourth, you can contact your county ordinance department, usually those who handle house condemnations and mowing liens, and provide them with the property tax number, photos of the violation with a complaint from the named neighbor about the risk. 

I would like to know your strategy for finding these landlords, especially in large apartment buildings if you are dealing with a property management company

its pretty common .. in the PNW there are large communities and this pattern happens more than one might imagine..
