@Zana Blue Usually privacy issues.

The land lord said that he couldn't know who his room mates were until he signed the lease because of privacy issues. 

It is easier to find tenants for the SFRs and you will receive a premium for the yard and privacy vs a town house or condo.  

I only found out after seeing a sign posted on a back sliding glass door (privacy fence gate was open) that said, Residents must smoke outside.

It also makes GLA estimates easy as pie and measuring for privacy fences a snap.The laser measure makes taking interior dimensions super fast and simple.For measuring cabinets, however...

The building still sits on a large lot, with backyard, etc. and, from the outside looks like a large SFR.The advantage of a *plex over having roomers/boarders in a SFR, from my perspective, is you still have others helping pay the mortgage, but you do not have to share a kitchen/ bathroom and can maintain your {and their} privacy.

Tell her you are not able to discuss any matters pertaining to the tenant as a matter of privacy.

Personally, I wouldn't rent out my pool because:(1) liability - as a former insurance professional, liability is always something I'm concerned about, and pools are a big source of liability concerns.(2) me time - I enjoy my privacy and don't want strangers in my house, let alone my pool, but also I actually use my pool a lot so this might not be too much of a concern to others(3) safety/accessibility - if I'm living at the location where the pool is, then that means people will have easier access to me, whether that means knocking on my door during their pool party to ask questions or voice concerns, or seeing my home which may put me/my property at risk in the future if someone less savory or with sticky fingers happens to be renting the pool. 

Probably good privacy practice (not giving their info).  

Bear in mind these items are held in public record so you are not violating privacy by disclosing information found in public record on BP posts - it is already private.
