Self-made millionaire David Bach was quoted in a CNBC article explaining that "the single biggest mistake millennials are making" is not purchasing a home because buying real estate is "an escalator to wealth."

Bach went on to explain:

"If millennials don't buy a home, their chances of actually having any wealth in this country are little to none. The average homeowner to this day is 38 times wealthier than a renter."

In his bestselling book, "The Automatic Millionaire," Bach does the math:

"As a renter, you can easily spend half a million dollars or more on rent over the years ($1,500 a month for 30 years comes to $540,000), and in the end wind up just where you started — owning nothing. Or you can buy a house and spend the same amount paying down a mortgage, and in the end wind up owning your own home free and clear!"
