I'm new to BP as well... my great grandparents from Germany and Denmark planted our family out in Elgin. 

I would be very cautious of water treatment plants as it has to be tested very frequently, at least thats what I have found, plus the enormous expense if there is problems.9 homes over 4 acres?

Where if grow our own plants etc... that become our inventory to rent out and sell (vs. buying them wholesale).  

Cottage grove has lots of blue collar industry, Minnesota Mining and Manufacturing (3M) has a plant there so you will probably always have renters.http://www.3m.com/3M/en_US/plant-locations-us/cottagegrove/

I'm an investor in Lakeland area to Brandon area as I live in the middle in Plant City.  

There are also several major energy companies building new power plants in the area, bringing 100s of new construction jobs, and 100-200 permanent jobs. 

I think the inflation we're experiencing in this market is actually because of the anticipated growth of the industrial sector in Mobile with the new Airbus manufacturing plant, and consequently an expected growth in the residential and commercial demand on the Eastern shore of Mobile bay in combination with the national real estate trend to higher prices.

They are the people you see working on the large steel erections at a petrochemical refinery and associated nitrogen fertilizer plant.

And I mean high high probability as in they're building a new Hewlett-Packard plant or a University nearby in the near future.

I'm next door in Plant City but focus my investing in Polk county.
