You have to pay to set it, you have yearly renewal fees, and then sometimes additional costs for accounting.

I'm wondering if I should start with a 3 month lease so I don't encounter an off-season market every time the lease renews - or 15 month? 

P.S not interested in hiring a Broker, because giving them 10% for a lease renewal will actually cost me more than the amount I would receive due to the rent increaseThanks,Cramer

I could also consider putting an ad Fee Structure: Property Management Fee:7% of monthly rent collectedLeasing Fee:50% of one month's rent, which includes Free Eviction Protection, a 30-Day Rent Guarantee and a Quality Tenant GuaranteeRenewal Leasing Fee:2% of annual gross renewal rentMaintenance Fee:Billed at invoice cost plus 10% administrative mark-upProperty Setup Fee:NoneMarketing Fee:NoneProject Management Fee:10% of project costs above $5,000

I'm currently under contract on a smaller, 5-unit commercial office/retail property. 4 of the 5 leases expire in April/May of this year, and one of the contingencies of the sale closing is that 3 of those 4 soon-expiring leases renew for at least one year (I have full negotiating power over those leases).All of those tenants have showed no intention to vacate, and are happy with their current situations.I've seen/read in many places that it is best practice to stagger leases as much as possible in order to avoid the possibility of multiple tenants moving out around the same time, leaving numerous units to be turned over.Would it best for me to try and get 2 of the 4 tenants to renew a two-year lease (which they've done in past) and the other two tenants agree to a one-year or three-year lease (both have been year-to-year in past ).

From what the seller has told me all of the tenants are willing to renew their leases, and the commercial unit is still under lease for another 2 years. 

If you find it’s not for you, you don’t like talking with tenants, coordinating lease renewals, etc, by all means - find a GOOD PM.

Let's say I can bump rents up to $650 when leases are renewed.

I have a tenant that is ignoring my attempts to contact, his lease ends tomorrow, he was given 30 days notice that lease will not be renewed.

The right thing for Tenant B to do is start paying his share by splitting the water bill.It sounds like he will refuse, so you move to Plan B and tell him that because he refuses to play ball, you will not be renewing his lease when it ends.
