House needs some Interior Cosmetic Work, Wood Fence Repairs and some Plumbing Work.I want to turn and run, but I recently heard where there is a Problem, there is Opportunity.I thought this might be an interesting Case Study.Thanks for the Ideas.If they owe $180k on a $210k property and its a year+ behind then they probably owe taxes and other bills as well.

(We had a boat as an AirBNB and the plumbing would clog very easily and we had to state a similar statement and it got us out of refunds and bad reviews) hope that helps! 

Plus, very important to understand the new layout and how the dig down will effect the existing stairs, plumbing, etc.Happy to connect and talk through your specific situation because @Bruce Woodruff mentioned every project is different and know one price fits all espeically with these complex jobs.Where at in Chicago is your building?

Structurally, the property is in pretty good shape EXCEPT one problem that I cannot properly assess: the plumbing will not hold pressure.

Also doing all new plumbing and electric service/panel upgrade to 200amps.

Purchase price: $105,000 Cash invested: $90,000 Property needed some serious rehab, from trees roots destroying the basement walls, to plumbing, electrical, to roofing, landscape.

We did $20,000 of rehab with the new wiring plumbing, rear porch, landscaping, garage teardown & drywall.
