during a recession houses are all over the floor in prices...you buy: 500 houses at very low prices like if you was rich...

you wait 10 years because in 10 years the economy will pick up...then you sell them at: $50,000 extra than what you bought them for...

$500 x $50,000 = $25 Million dollars that you made...

in the mean time while the 10 or 12 years are passing along you rent them:

$500 x $500 a month = $250,000

$250,000 x 12 month = $3 Million dollars...

$3 Million dollars x 10 years or 12 years = $36 Million dollars...

$36 Million dollars x $25 Million dollars = $61 Million dollars...

imagine if you had bought: 1,000 homes instead of: 500 homes...Would had been the double...

and yes you get your money back also the one you spent...
