I managed one site that had a resident with a Rottweiler as a service dog, even though that was a prohibited animal on the site.

I've seen many landlords here state that they do not allow smoking in their buildings, and that they prohibit that in their leases.  

I'm not an ERISA attorney, but I think this is a very clear example of what would be a prohibited transaction -- first, because it's your primary residence, and second, because you own the property in non-retirement vehicles.

Up front costs are big and most likely prohibitive.

Even if your laws prohibit this, you can still probably appear outside anytime. 

There are LOTS of reasons to invest in real estate, and to believe that only through leverage can someone reach their financial goals is very naive.While many of us need leverage to meet our goals, there are plenty of investors out there who have financial goals where leverage not only isn't needed, but would be prohibitive to meeting their goals.

DENYING ADMISSIONS - MANDATORY PROVISIONS Owners are required to adopt and incorporate into their screening and admissions policies the following mandatory provisions that prohibit admission to applicants who fit into the following categories.

Account ClosedI'm curious what your basis for such alarm is.The risk of engaging in a prohibited transaction is really no different whether you work with a custodian or an advisory firm that implements and supports checkbook plans.A custodian provides no significant oversight regarding the compliance of transactions.

this was this first thing I read on a zoning person "Prohibit exterior physical changes to the home for the purposes of business" so chances don't seem too good

I thought their sites state it is prohibited?
