@Paul Lee I don't see the problem being with duplexes and triplexes, but more-so elevators, subways and traffic jams.

When that time comes, focusing on an strategy will significantly elevate your game, not that you have to stay in one strategy forever.

Decision points, Cost of land, Availability of land, Customer service- drive up versus elevator, Business model, etc. 

Watch out for any properties close to a Bayou or Greenbelt and properties with very low elevation. 

You definitely want to include a detailed specifications document that everyone signs of on for all detailed construction specs, electrical layout, door swings, selections, fixtures, finishes, elevations and shop drawings for any built-ins  detailed trim work and specific mechanical and electrical locations.

It's literally "the other side of the tracks" and is a rougher area separated by a large physical barrier that runs east and west (elevated train tracks).

For every 18 feet into the mountain, the elevation rises by 10' (approximately).The utilities are already ran to the roadside... 

But as you can see, my "elevator pitch" is a little long and it is hard to communicate all this experience to most people.
