EPA, storm pond, 2 acres doesn't seem like much to put 6 duplexes on-  parking, driveways, setbacks, landscaping, fences, soil test, fire hydrants, survey, etc. 

Make sure you inspect all units, including roofs, foundation, HVAC, water heaters, plumbing, electrical, etc. if you will be demolishing walls you might need an asbestos survey and this can be costly if you find asbestos.

@Carl JungHi Carl, obviously the decision here depends on your priorities and values, what I think you're really looking for here is to get an outside perspective on how each decision might line up with those values, gather ideas you might not have considered, survey other people's opinions, and just generally try to move towards greater clarity on a complex decision. 

Whereas you could get in out of each unit in a hour or two with a replacement (great time to survey/inspect the units, too, for a dual purpose trip).

Survey. : when getting insurance coverage, are you guys selecting replacement cost or actual cash value;ACV) ????

I had my property lines survey on a rental property and found out that a tree in the middle of the fence line is actually on my neighbors property and not both of ours as I originally thought.

The property did not meet conventional financing requirements, so I was forced to purchase with a commercial loan.Also, the property requires flood insurance, but I was able to get it surveyed and recieved a $2000/yr reduction in premiums.

I underestimated how long this would take, since there was some custom coding needed.I created a multi step survey that asks questions about motivation, price, and the property.

@Josh Hurles lenders use what the appraisal rental survey says is MARKET rents minus PITI+HOA AND you need reserves of all your total bills plus the subject.
