Our next door neighbor is deceased, according to property records and we always thought the property is vacant but someone showed up and started throwing bricks at the new sliding door we installed, my workers heard the loud noise and went to check and they claim to see a weapon on his hand and fled the property. 

I've done over 75 flips in the past 3 years, we manage 300+ doors, and I own 28 long term rentals. 

A big issue however is the home next door.

I've heard of agents riding around town just opening doors and hoping the buyer will pick something.

The main house shares a front door, but the first and second floors are both separate units.

Hi Brian, I'm not too familiar with the Columbus market but I do have 9 doors across Detroit and Memphis.

How many properties/doors should I manage for Story to make sense?

It is different for the elderly couple who has lived in their house for 30 years and now has a large building constructed directly next door and wants to erect a fence that exceeds the max height allowed.

I own 20 doors which provides nice income. 

Today, 7 years later,  I have 37 doors and real estate is my full time job managing those properties.I doubt anyone can tell you exactly what course you should take… but if real estate is your goal, my suggestion is to go find your local real estate investment group that probably meets once a month and start rubbing shoulders with everyone there.
