However, typically builders allow assignments only when a substantial units of the building have sold, say 80% as an example, which means these are the more desirable units, the 10% are less desirable i.e. close to the garbage, no balcony, traffic noise, etc.

Slightly more risky IMO but with the guaranty of occupying at least the residential units & my desire to open up another small business this year, I cannot resist.

The primary use would likely be in basements but I can see this developed into windows that track the actual sun if desired.

States around NY doesn't seem to be very desirable or just as expensive/high in taxes like NJ, CT, PA.

You'll be able to spend as much time with your friend as you can desire after you become a good entrepreneur.  

I could be slightly biased in my desire to maintain access to those calculators...and when do we become "not" Newbies. 

If you don't have a burning desire to start a business and if you're not willing to eat, breath and sleep it, then it may be best to continue the formal path until you find your true passion.

Another option is to make sure you're pre approved for a loan amount to buy in your desired area, if you're not pre approved maybe ask a family member who is not planing to invest or request loans in the next 5-10  years to   co sign on loan.  

It is nice to be able to crank it open when desired.

I think you're down to an average of a 6 month supply of homes on the market there which means supply is tightening up and the market is strong.It should be a great place to pursue any type or strategy in real estate you desire while you get started!
