Very different answers to your question depending on the answer to this one.If for a career path, I would agree with @Michael K Gallagher and find a brokerage that is actively doing deals, has a property management division in house, and has brokers covering each of the key market segments - multi-family, retail, office, industrial and land.

The housing office will then either approve the rent amount or tell me I have to lower it based on the tenant.

2 Years ago today, instead of renting a studio apartment, I bought this 3/2 single famliy house in Apopka, Florida, rented out the 3 rooms and converted the office into my bedroom.

In Franklinton there are plenty of large projects going on that will bring massive growth to the west side of Columbus, such as the Peninsula Development, which is a multiphase project that will erect a 24 story apartment complex featuring a grocery store, a multi use office space building, and a new hotel featuring a two-story Pins Mechanical venue.

In general, the major brokerages are somewhat greedy and they would prefer to keep both sides of the commission "in house", so before any new listing is posted to a site like LoopNet, Costar or Crexi, it is passed internally to every other broker in the office and then within the intranet for that company, to see if anyone has a party to do the deal with.

Be conscious of people's time and be respectful of the work your loan officer/broker is putting in to get your deal to the closing table.

Tenants can range from very good executives at Abbotts & officers at Great Lakes to some of the sketchiest tenants.  

I have a big library of courses currently it takes up 3 rooms of my office. 

I own four small office buildings, a 10,000 sq ft retail building that we rent to a daycare, and a 24,000 sq ft warehouse that we are renovating.

But then the new tenant probably will throw it away.Should the friend take it to the Post office and let them know to send it back to me?
