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?

@Bryan Cavellier While you certainly can do that, there are different state rules and laws to be aware of.

But as for the seller finance, would the loan to the seller be the difference between 450k and the refinance number of 220k?

You've made numerous false statements about how financing works.

Our portion out-of-pocket was the $3K deductible.I'm friends with numerous apartment owners. 

The differences lie in how they aggregate, update, and present the data.

Every bank is looking for something different and it changes over time.However, we are not in a BRRRR market anymore, you'd be sailing upwind. 

Luckily our tenant is easy going. his entrance has a different front door but not his own house number. 

Seems like that has a bigger difference than you'd expect. 

How is it different than having a multifamily property or SFH will S8 tenants?
