(renters is key word, I think there's more of an appeal for homeowners and those with families - I'm making an assumption that the majority of families in southern NH with an adult commuting into Boston are buying and not renting, but please correct me if I'm wrong)  To me I think the draw to southern NH needs to come from growth in southern NH (such as the tech you've mentioned), or growth north of route 3/95. 

My tenants had never had more then a $10 increase under the old owner, I increase by $30 a pop on most controlled units the building  was profitable regardless.

One major appeal is that real estate is a tangible asset that you can physically control as opposed to the the stock market where we have 0% influence on our investments.

No major flooding.  

You have to find something that you can add value to in order to make it profitable.

Details yet to come, hopefully we can at least retain some profit out of this quagmire!

First, I would identify the average price points of the majority of recent sales in your area that you want to work in.  

I guess the best answer is when someone goes through a major change, chances are greater that things can go wrong.

the 70% rule allows you to have 10-20% profit, depending on situations.

We split all profit 50/50.Using super simple numbers to make the math easy.
