Most of the information that I find online says that a person needs a license to rent or lease properties unless they are the owner of the properties being rented, but I can't seem to find anything that specifies if I/we, as employee(s)/agent(s) of the LLC that owns the properties which I/we manage (including showing and negotiating rental/leasing agreements), am technically exempt or required to be licensed as a broker.Any advice would be greatly appreciated.

I have been doing the residential for a while and know how to advertise, write leases, and work them.

Even 10% might be low, not including cost of placing tenants, lease renewals, etc -- but if you're self-managing I would just erase that cost entirely.3) $35/month in repairs -- not even sure where that comes from -- Even in a brand new building that's way too low. 

No lease can be found and the tenants (or at this point, squatters) are refusing to leave.

Under a coop you have a lease so it will apply, I am unsure whether it would apply to a condo, but you should look into it.

We can also require the program to have a 2 year lease agreement, which adds value and slows turnover rates.

The three most common products that qualify for 1031 treatment and tax deferral but are absolutely passive in nature are the Tenants In Common (TIC), the NNN lease or ground lease, and the Delaware Statutory Trust. 

My initial goal was to do airbnb with it but I called the leasing office and found out it's not allowed.

Do you have any tips on how to prevent renters and cleaners from taking all your extra supplies (like how people take shampoos at a hotel)?

Use the remaining cash to purchase a passive investment 1031 compatible vehicle like a TIC or NNN lease and pay tax on the mortgage buy down.
