Being a landlord isn't a way for someone who doesn't have wealth to acquire it. It's a way to park your existing wealth in quickly appreciating assets preferably purchased from other losers when they lose their asses and collect monthly rent too.
If on day one you have 700k and you purchase an existing property and in 30 days after you rent it out your property is still worth 700k and you are now ahead of the game in 30 days not 30 years.
If you purchased at a reasonable time a year later its worth 750 and you've collected 84k 1% of property value per month.
Most owners are in the top 10% to start with.
