@Amy DeCesare While the areas you mention could certainly benefit from more multi-family units, generally people in the more affluent parts of the state like Washington county oppose such new development, either indirectly through zoning ordinances like minimum lot size and parking requirements that make it almost impossible to build (as @Brandon Ingegneri mentioned), or directly at zoning hearings where neighbors show up and oppose it because that they don't want to change the "character" of their neighborhood.It can be done, but it's far more the exception than the rule and requires big bucks, political savviness, and the ability to make a big bet and absorb the loss if you lose.

You still need to worry proper maintenance, proper insurance and umbrella insurance, proper property management, etc.

Like I said, I had a similar situation, and if you place all of the pieces properly on the board, you already have a recipe for success. 

What if the seller of the home doesn’t want to get a agent involved but your the wholesaler of the dealHow do you close the deal out properly and make easy cash?

The piece I wanted went higher than I wanted to pay, but then that was bounced by a developer who bought all 30 acres plus the house.

I need to develop a team to punch out a similar deal.  

It's a fully developed town and all but it's a little run down.

We are a real estate developer seeking land for acquisition and development. 

Also it’s in a development which could lead to future ownership of other units adjacent to the property.
