I am a retired Math and Science teacher of 25 years.  

RE is not rocket science. 

I am a construction project manager, currently managing a $1B life science project in Cambridge, MA.

Real estate investment is more art than actual science.

I could absorb social sciences like a sponge from a very young age.

Ultimately it's less of a science than an art, but people rarely truly change so what they did is probably what they'll do.

House hacking is science, especially in New Jersey. 

The city has excellent fundamentals...strong Ed's and Med's which are some of the most stable employers, huge investments made in the life science sector,  proximity and easy access to NYC and DC, international airport, port city to name a few. 

Residential investing is not rocket science, knowledge is not the issue: there are many good books out there that walk you through every detail you need to know.

Honestly I think most buyer's agents don't/won't do it.I think in 95% of the cases a FSBO seller could not put together the info I do for the appraiser or would even have the first clue as to what or how to do it.It's not rocket science and maybe not really brain work, it's just access to the info.For example there are neighborhoods where I've sold the same house 3 times.
