Get your license and open a lot more door than trying to broker without a license. 

More on that in a bit, I will start out with my first walk-around after the purchase.I was excited to get to my building and see what needed to be done, I opened the door went and walked around in the one available unit that was open out of four.

You can also look up Zillow, Redfin, Trulia, etc...For off-market properties, you can go directly to seller by getting a property list and marketing to the seller (calls, mail, door knocking).

The marketing would include open houses, professional photos, Facebook ads, newspaper or magazine ads, eFlyers to other agents, flyer hard-copies for the open house, door hangers when door knocking, etc.

For me, it was very much How to Study in College but after that, it was another lucky find, an old book called Profits in Buying and Renovating Homes by Lawrence Dworin that got me into rehabbing houses for rent, and then still later in personal finance, it was very much The Millionaire Next Door by Stanley and Danko.

Plus I’m going to be standing at the front door fuming demanding to know when I’m getting paid and what the issue is .

I would like to stay multi family and would like to be at $200 per door.  

They will likely turn it into a rental, as most are around here now, and therefore won't care one way or the other about the fence, but I wonder whether bumping my price up to cover the fence cost would lose those potential buyers.For those curious, the reason for the single-side fencing is the rental property next door on that side.

Between myself and my partners we own 50+ doors in Ontario.Would be happy to chat :)

Last property I bought there was $25k/door.
