@Dimitris KontonikolasThis doesn’t sound code compliant.  

We buy the Schlage electronic code deadbolt/handle combo.

You could check out www.datausa.io and type in the city name or zip code.

The real estate industry has really a low bar for entry. 

I have a good relationship with the code enforcement officer in the city, so he joined me for the tour. 

Look into your state or local property code about what you can do about a slum lord.

Right now I have a 30" island with an area for bar stools so that can be shortened as well.

So your 75% off list price minus rehab costs sets the bar too high (or too low rather) right from the start.Also, after briefly reviewing the comps, I think it's more likely you OVER estimated the ARV.

But there might also be a good reason for it that they can explain.Some other things that might apply to your deal as you head towards closing:- Typically there's some kind of review of the preliminary title report (to show any encroachments, liens on the property that will be paid off by escrow at closing, any covenants/codes/restrictions that are recorded on the property, etc.)

This may be a code violation issue.
