Your best bet might be to check with Planning and Code.

My neighbor said on a face book town page - she was thinking of putting the house up for sale- She did not really did not want anyone in the house because she is a hoarder & had her special needs son living in the basement apt- with NO egress window ( against fire code) / I told her we could do the deal with lawyers - and save money on real estate agents (at that time the seller paid all commissions) How did you finance this deal?

These are professionals with additional training and a stricter code of ethics.

They were issues that did not meet building codes everywhere.

The building was built prior to 1938, so there is no certificate of occupancy issued; not sure if that helps me at all.Thank you.Without looking at picture, it is hard to see.Is everything following with the code ?

Does anyone have experience with owning these types washer/dryer machines that use the QR code/coinless and ease of use and reliability?

Depending on how strict they are, they could make you tear them down or at least bring them up to current code with inspections.You might want to go down to the Building Dept (or call) and ask (without giving an address) what they would recommend.

Anyone got a good recommendation for websites that can provide me a deeper analysis of a neighborhood, preferably on a zip code basis?

Pretty soon here I plan to get a QR code to the direct booking site for my listings and put them on a fridge magnet or coffee mug. 

Very hard to repair as:1) Color codes change fast these days2) Leaving a box of spares leads to tenants breaking the whole box or throwing them away:(LVP is better, but you have to get the thicker stuff and install it correctly.
