House Hacking + 25k to invest

[Dean Klein]

I am purchasing my first duplex to live in and rent the other side out next Month, it's currently under contract, I am putting 20% down, after that, I will have approx 25k left, I want to get another duplex within 5 years, I can't qualify for anymore mortgages, the goal is not cashflow right now, although, I won't buy a property unless it does cash flow well, but the ultimate goal is to pay off a few multi's then have a nice steady stream of income for the rest of my life, should I wait 4-5 years until I have enough to purchase another building outright or should I try and get a couple owner financed deals but the problem is since I can't get another mortgage, I don't know I'd make a balloon payment.
