If I had been in a hurry and pulled into the intersection right after getting green light, I would not be here right now...

It is one block from the biggest retail / restaurant / bar intersection in the area. 

The land is located on a busy intersection between and interstate and US highway.

The rental price must be consistant with the median income of the renters you desire to attract.The intersection of these four factors are what I call the "Sweet spot".

I have a 2 unit at the intersection of 84/91 on the main bus line into Hartford that might be interesting.  

An intersection of interests."

Throw them in your trunk (yes, if I can do this with a honda accord, you can do it with anything)-Keep your hammer under your seat (bigger hammer = more leverage = easier to get into the ground)-Drive to the intersection, put on your hazards, and just scramble to put them on all sides.

@Rafael Velasco the one thing I look for in buy and hold is the intersection between easy landlording and cash flow (sneaky way to include a bunch of factors :) ).  

Put them out at intersections in the neighborhood your targeting.

My parents have residence & partial ownership of adjacent corner lot (family property)- heavily traveled hwy, busy intersection w/ strong demos & traffic counts- future zoning GC.
