How do you keep buying rental property when you run out of down payment money

[John Kim]

So my problem is that I have enough money for a down payment for 1 more rental property.

Once that is gone, I have no more money for any more down payments.

I work a full time w2 job so i can't spend the time to flip a house.

How do you guys keep buying properties when you run out of money for down payments?
