You could state this in the lease telling them that they will need to apply all regulations pertaining to the "Drug Free Zone" so that as they definition changes you won't have to change the lease.

There are many more regulations in the EPA pipe right now, and knowing your system will help you know the costs. 

Sorry, @Hattie Dizmond but this is just plain wrong:However, generally, it would only be a HOA that would limit the signs that could be posted on the truly private part of your private property.Cities can and do regulate signs on private property.  

SEC regulations limit you to either people you know (no advertising) or accredited investors. 

Maryland has very strict laws about pre-foreclosure marketing with very hefty penalties

When you are selling shares of interest in real property, those interests are securities and you must observe the laws and regulations relating to securities.

Your not looking to work with contractors, you highlighted at the beginning you hire unlicensed persons, those are NOT contractors than, they are subs and you are trying to side step what you should be doing because thats probably where most or all your profit lies, not in the deal of the property but in finagling to get done what should be say 50K done for 30K by side stepping regulations and hiring overqualified desperate persons. 

As for wholesaling, it's strictly a numbers game where I require at least $500 a month to direct mail marketing.3.

Where I am, we are regulated much more stringently and we cannot be the license holder for another contractor, so to me that just sounds strange but you're there so you're information is clearly more accurate than mine, but it does bring up some questions that @Erin Bryant may want to know from a liability standpoint.

Don't know about multiple doors but the above will be true anytime you are borrowing from a regulated institution.
