According to the Urban Dictionary, "Old School" is "Anything that is from an earlier era and looked upon with high regard or respect."  That is most certainly buying turnkey properties in the genre of high yield real estate investing.

 Turnkey properties are those that have been bought, fixed up, rented out to a suitable tenant and then managed for the new owner.  This requires very experienced "Old School" real estate professionals to make this profitable for the new owners.  Jerry Cohen, Founder and President of EquityBuild, a real estate investment firm, has been a principal in more than 1000 real estate transactions since 1984.  

An entity that has lasted that long in a sector as competitive as real estate is certainly worthy of "high regard and respect."

What makes investing in turnkey properties "old school" is the reliance on those who are held in "high regard and respect."  Passively investing with the purchase of a turnkey property from the seasoned experts at EquityBuild puts their decades of experiences with legions of transactions on the side of the buyer.  That removes a great deal of the risk from the transaction.

Passively investing for the long term ensures that the power of time also accompanies the turnkey properties.  Over the last 200 years, real estate has created about 90% of the world's millionaires.  Real estate investing has obviously withstood the test of time to become "old school."

If the turnkey property is rented out, the long term approach is even more rewarding.

Rental income in the United States increases about 5% annually.  Even during The Great Recession when the price of stocks and bonds plunged, the level of rental income in the United States rose.  Increasing 5% annually means that the rental income received from a turnkey property will double in less than 15 years.

Putting turnkey properties in a retirement account will make the returns even more rewarding.  When assets are held in a retirement account such as an individual retirement account (IRA), the income and profits from its sale are tax free.  If the turnkey property had tenants, there would be no taxes on the rental income.  Should it be sold for a profit, there would be no taxes on the gains so long as it was part of a retirement account.

Old school investing in turnkey properties with a company such as EquityBuild has proved its value.  Passive investing with a long term approach is the best way to profit from turnkey properties.  Sometimes the ways that worked in the past will work the best in the future, especially when it is investing in turnkey properties.
