The only exception I found is a court case in NJ that related to suppression of a gun search and did say tenants in a boarding house had an expectation of privacy as regards to common areas and that search.

I am unfamiliar with "fire Suppress"?

Additionally, most condo's that allow STR in the HOA do not require this or it's already installed, however, any free standing property, duplex's and other properties require a fire suppression system.

Repainted the walls etc with 'mold suppressive' paint & again upgraded the old exhaust fan.

We built our 16 person cabin with fire suppression in it because we didn't want to play games with the definition of bedrooms to skirt around the regulations.While I don't disagree with the point your making, I will say that our interactions with the fire marshals and city officials have been way better than we expected. 

It does seem that higher rates are reducing demand for loans, which is driving up home inventory which could - I stress could - suppress home price growth.

If it is bad enough that can suppress rental rates but a family looking for $2000/month rental is not going to consider $3000/month units.

Storm pond, storm sewer, fire hydrant, fire suppression systems, fire walls, electric metering and voltage (3phase???)

Millions upon millions of jobs lost "forever" ("exported" to the "third world"), more millions lost half or more of their retirement accounts, creditors slashed and burned consumer credit to the point where, by the banksters' own numbers, some 74% of Americans wound up with "bad" credit (it was only 47% before they did that), ...Now, add in the knee-jerk responses in the lending industry and you've got a situation where only the elite of formerly middle-class wage earners can even hope to qualify for new home loans.In fact, the given the current housing shortage (yet more fallout from the crash), it is ONLY the dearth of lending which is keeping home prices from launching into interstellar space by suppressing demand.

@Logan HandWhen you say that you try for a fresh list every month, do you mean suppressing your old lists?
