Buy investment multifamily w/ mortgage or mortgage second home?

[Louis Zameryka]

I am looking to buy a duplex as an investment property. I do not really have the cash for the down payment at the moment but I own a second home that is free and clear. I’d like advice as to how I should pay for the investment property. Either cover the down payment on the investment property mortgage via a heloc on the second home or cover me buying the investment property outright via a mortgage on my second home?

Any advice on the smartest way to structure the purchase?

Thanks
