And unlike a property manager who specializes in leases or a residential broker who specializes in home sales, I have built my business with a laser-focus on apartment buildings.

My CPA and advisors have told me that it's imperative I switch my income stream and I'm laser focused on doing so now.

They essentially stand at the corners of lots with laser measures to calculate square footage of the structures and property.

Focus on getting business - until you have a client nothing else matters...you need to be laser focused on acquiring clients.  

So day care, hair cutting, massages, psychic palm reading etc...are not allowed, but if they are selling stuff through eBay and needs the UPS or Fedex trucks to come pick up twice a day I don't have a problem with it.However with more and more people "subing" out rooms via Airbnb I wonder if I should add a clause in there specifically addressing it.I know many people are doing it because I use Airbnb when travelling overseas, and I often read in the ads SPECIAL INSTRUCTIONS saying "...do not go to the property directly so as to confuse neighbors or property management, meet me at the designated meeting location then I'll guild you to the location quietly..."

Lol looks like what we find here in Portland, OR - several decades ago there was an invasion of denim-clad homeowners with Big Hair who decided to cover all the hardwoods with garish carpets, possibly because carpet was less likely to get dented when they dropped their pet rocks. 

Laser, not shotgun.

No one falls through the cracks in those zip codes.I also have a VA doing a stealth fighter with laser guided smart bombs campaign to landlords doing their own evictions in my metro area.I've got a ways to go but so far, making more money than it's costing me. 

I'm 61 and the same guy has been cutting my hair since I was 18.

I'm thinking it's legit so long as they haven't been used unless some post office has some strict guidelines or you bought "uncancelled" ones that were actually cancelled through some UV laser scan method I only just read a little something about rather than the obvious black ink stamp method.
