The city may require you to put up to 125% of the estimated cost to correct said POS violations into escrow until repairs are made.

Still need to watch for any unpaid property taxes, code violations, any HOA's.  

Hey at least if they violate the clause that may or may not allow pets you can charge them an additional $0 / day for 0 days.

If you know at the time of offer that the tenant is in violation of their contractual obligations - particularly if this is a continuing ore recurring behaviour, have the Vendor deal with the eviction as a condition of sale.

I was unaware that Neighborhood Code Violations might not be recorded.

If there is a section in there about no illegal activity, I'd send them a copy of the photo, page of lease with section highlighted, and a notice saying you've been informed of possible illegal activity regarding their rental unit, please remedy the situation as you will have to follow lease terms (eviction, notify authorities, etc.) if informed of future violations.  

The issue is you have to be up to code when the violation is discovered, not when it was built....and building codes changed last year IIRC.

If they're not licensed they're not an architect and if the architect stamping the drawings isn't directly responsible for the drawings then they are in violation of licensing laws and could lose their license and could be permanently banned from practicing.

Obviously doing it with my SD IRA (to myself or my LLC) is a violation of IRS rules.

Here I would get a notice from the city/inspector, typically in the mail, that I, the owner, need to correct the xyz code violation(s) within x days.
