McKinney and Princeton have been growing a lot and it is a good place to invest, but it is always related to what you are looking to achieve in a rental investment, appreciation or cash flow.At this time that area does not offer a big cash flow and due to the amount of development going on there, rental demand has declined a bit.In any case you have to make an analysis case by case.

I can also see the ends of the Commuter Rail lines being good too...like Haverhill for instance  The Salem/Beverly area is great and pretty pro-development/housing from what I'm hearing.

Getting Fair deals on labor and repairs comes from developing win/win relationships with contractors.

I developed friendships and met a lot of great people at Rod's event and value his input and what he's doing for MFH community. 

Keep in mind I dont do rental properties we do land projects new builds and capital partner with other developers who need capital.. 

Don't wait for problems to happen before developing a solution.
