Another book I enjoyed reading a while back is "The New Elite" by Taylor & Harrison.Jim Taylor and Doug Harrison define this "Elite" group as “people in the top 1 percent of half of 1 percent of the American economic spectrum: These people typically have at least $5 million in liquid assets (i.e., not including their primary residence) or have at least $500,000 in annual discretionary income.”

Or on the other end of the spectrum as a retail business, professional office etc.

My name is Christopher PerezI am looking for a opportunity to apprentice as i am learning the Wholesaling market.I believe this is a sensitive area of the Real Estate spectrum and would like to really put forth the hard work and integrity dealing with my clients and especially my potential investors.

Managers of small buildings tend to be on the lower end of the spectrum in terms of skill set so they take more hand holding.IMO if you sell your duplex and purchase a property that needs property management, you will be back in the same place in short order.

Thought everyone might be interested in this look at changing trends in the housing market and the increase in households who are renting across the income and across the demographic spectrum. http://www.washingtonpost.com/blogs/wonkblog/wp/2015/06/24/how-renting-became-the-new-homeownership/?

Fill another niche.They can't rent to everyone.They won't rent to just anyone.They don't have the best location for everyone.They are usually at the upper end in the rent spectrum for those amenities, does everyone want them? 

I am from New York City which falls on the other side of the spectrum.

Believe it or not there are people out there on the other end of the spectrum and they have billions of dollars that need to be placed, to them a 5% return on a very safe apartment complex is a great deal.

I also heard the full spectrum of opinions; it's easier to negotiate down than up, while others contend that setting my price below the market will stimulate a bidding frenzy. 

On the other end of the spectrum, I've briefly viewed properties where we went to college in Florida, and I could buy a 4-plex for 170k, pay 850/mo, rent out three units for 600/mo ea, and net +900/mo minus expenses, plus live rent free myself.
