Now for my out-of-pocket expenses:Down payment: $7500 (Hard money loan 90% purchase price 100% rehab)Closing costs: $6500Inspection: $400Agent's commission: $5200 (didn't raise purchase price of house with seller concessions, so that money didn't apply to the commission sadly. won't make this mistake again)Holding costs: $1300 (one interest-only payment of $770, roughly $200 in utilities and $360 in insurance)Total: roughly 21 grand. 

Maybe they work for the fiber company and they want to put some kind of utility hub there.   

More specific: He stole months of rent and utility payments from a tenant (and threatened to evict her!)

Are you printing standard envelopes #10 etc or do you print any heavier weight or custom size envelopes?

Remain responsible for rent, utilities, and other terms until a replacement tenant takes over.#2 can be a bad option in the middle of winter when renters are harder to find.

From time to time I will hear of people who utilize it well and gain business from it. 

On one occasion I overheard two customers chatting in the waiting room and they had no idea I was the owner.

Rent out part of the space at least to help pay for mortgage and utilities.  

Also, how do you deal with utilities?

This step would include understanding City zoning & platting, locating utilities, researching City codes for development requirements (big ones include detention), etc.
