I plan to utilize some cash, margin loan, 401k loan, and a HELOC as a down payment.My first house hack (now an out of state investment) has a Zestimate of $530K, and I have $266K left on the loan.

I own a single family home in Socal that my wife and i currently living in.

I’ve seen many buyers successfully execute this strategy over the years, turning such properties into valuable investments.

Investment Info:Single-family residence other investment.

Congratulations on your new investment property.Cheers! 

I'm still using it for flips and other investments but not trying to be long HELOC loans as 10% is still expensive money.If you want to talk more, I'd be happy to have a conversation.

Do you think a duplex is generally a better investment than a single-family home for rental purposes?

My answer is: Invest in the market you know best.Within Dayton, there surely are decent neighborhoods to invest in.

Quote from @Miguel Garcia: If I look into investing out of state should I look to get pre approved by a lender in that area or would a lender in my area be fine?

In other words, I think we will probably have to be on the hunt for a very good deal or a very distressed property, and will not be investing in million-dollar multifamily properties... yet!
