Roof in good shape, 80% of floors in great shape. 

Purchase price: $242,000 Cash invested: $125,000 Sale price: $492,000 Completely gutted and remodeled floor plan converting a 2bd/1 ba to a much much nicer 3bd/2bath!

Regardless, i’ve been advised to get some more first floor joists support via jackposts installation in basement to prevent any further foundation issues.

They work great.One benefit is that they make for a warmer floor in the winter. 

However, you can easily keep an eye out for either a single family home that you can create an in-law suite (whether in the basement, or converting a family room or other separate area of the house) or even a townhouse with a walkout exit that could have the bottom floor serve as an in-law suite.

But with 50K you can get a great Old brooklyn duplex for 130-160k, getting 800-900 per floor with next to no headaches.

The lowest par pricing I have seen this week for DSCR is 7.125% and the lowest floors at 6.50%, but getting to that floor rate makes no sense. 

The first floor needs some updating but the upstairs needs to be gutted because they had a roof leak years ago.  

The basement is about 800 sq ft with everything we need and separates us from the main floor (kitchen and living rooms) and 4 bedrooms upstairs.

Leaking valleys, dormers, lack of maintenance on flat roof surfaces, missing shingles/shakes all can create leaks that will run all the way down through the house, rotting framing, flooring, damaging ceilings and anything else the water comes in contact with from the very top to the very bottom of your structure.
