It was a rookie mistake, settling on a low number before we realized the demand.

In order to not have to pay PMI you would need a one loan program which does not demand PMI (not sure there are any out there anymore) or a larger down payment to keep the first lien less than 80% Loan to Value.

I came across a builder who will be building in a high demand town near Boston.

Agree with @Engelo Rumora on a micro level the rental housing demand I'm seeing is enough to keep me dipping back into the well.

Condos are a different animal, with the HOA fees it's Nearly impossible to cash flow.

My conservative side demands more when I am not confident in the abilities with someone I'm working with.  

Demand upon yourself to make at least $200-$300 (or some other acceptable amount) net profit before repairs.

These are 2 completely different animals.

The demands and expectations of landlords is much lower on the 4 unit or less, residential side.Second, insurance is much easier and cheaper on the residential side.
