help analyzing hypothetical deal

[Kim Forgione]

Newbie here still practicing deal analysis before making the plunge. Any number junkies care to see how well I'm doing with the below analysis? It's for buying land and building a triplex on it. Tenant pays all utilities. (These are researched costs; I didn't just pull the numbers out of thin air.) Would really appreciate constructive feedback to improve my skills :)

Side question: does the number in an R-zoning refer to the number of dwellings allowed per acre? I've found conflicting info on this and would like clarification. TIA!
