Everyone has different goals for investing in real estate.  Some people want to hit $XXX a year and live off of that income for retirement.  To do this, they need to obtain a certain number of properties, generally 5-10, that they’ll pay off before retiring. 

Most people run into difficulties acquiring that number of properties as it takes a significant amount of money to buy a home.  This means they need to optimize their wealth creation so they can get on the right track.
