Selecting neighborhoods and areas to invest

[Jeff Pagano]

Hello everyone, 

Like many on BP, I am new to the real estate world.  I joined bigger pockets about 4 years ago then took a hiatus.  In that time I got married, purchased my own home in NJ, and had a baby so learning about real estate took a back seat.  Now that things have settled down a bit I want to begin learning about the business again.  I'm mainly interested in buy&hold rentals.

One question I'm always wondering about is how are investors selecting areas to buy in?  New Jersey as any resident knows is a tough market and very expensive (it took us over a year to find our house), but I assume that it is relative wherever you may be.  

Are there any tools investors use to select neighborhoods?  If so what are some strategies/things to look for?

What are some things to avoid when looking for areas to buy?   

If anyone can offer any insight or advice I'd appreciate it!
