What to build? Duplex? Triplex? Quadplex?

[Mike Morrell]

I purchased some land last year in Rock Hill, SC that I am building my personal home on, and I was also able to subdivide off 4 one acre lots. The zoning on these lots allows for SFH, Duplex, Tri, or Quad and I was thinking about building to rent. I've got a blank slate here and just looking for some guidance. I'll have city water, but I'll have to put in a septic. My initial thought is quadplexes - more doors, lower $/door to build, more rental income.

Is there anything that I'm not considering?
