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

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

Quote from @Robyn Henderson: My family's 3 unit prewar building in Brooklyn recently had plumbing issues and I'm debating renovating each of the bathrooms.

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?

However I did note that houses are mostly really old, e.g. 100 years or older... any idea if this poses challenges in things like lead paint presence, outdated wiring, rusty plumbing, etc., or have many of the homes already been updated?   

My GUESS would be yes, if you touched the plumbing.

Does the cost per sqft account for electric and plumbing?
