Do you have a good resource for where I can find what 100-200 sq ft of office space rents for in a certain city (Simpsonville, SC in my case)?

His office is in Richmond.

If not received in your office on or before that date (preferrably the 1st of the month) then on the 3rd or 5th day past your rental due date, according to your contract, a late fee will be charged.If the tenant sends in their rent to me without their late fee, then I will call the tenant and let them know that they didn't include the late fee and that until I received their late fee, the eviction process is still on-going, but I will hold on to their check or money order until I receive their late fee, or until our court date. 

It is too hard to police everyday and not a workable system (you'd be stressed and in conflict and maybe violating their privacy if peeking in or around the place too much).

The office number is 215-744-HVAC. 

For example, providing the clerk and recorder's office a certified copy of the deceased birth certificate? 

@Jorge Magana Welcome to Bigger PocketsI recently opened my own office and work with investors.

Re-key the office or common areas2.

With the help of my real estate attorney, I contacted someone in the city office (can't remember what department), explained that property was vacant and acquired through tax sale, and received a refund of about $1000.

I work completely independently from my home office.
