Most build goals based upon the long term strategy, but buy based upon their short term strategy (cash flow).Since there isnt a politically correct way to say this, I will be a bit blunt.  

Smart buildings equipped with IoT devices can enhance operational efficiency and tenant experiences.

If you walk up to the contractor desk and order a pallet worth, you get a different price.

I’m eager to learn first hand the wholesale process - finding properties, building a buyers list, ins and outs of contracts and networking with agents, flippers and investors.

Stay in the job and snowball all my mortgages and let life coast or get off a job still snowball slowly and live life slower.Initially, when I purchased my first apartment building 10 years ago, I did it because I was curious.
