Best way to purchase 2ed property

[Matthew Mason]

I recently(2 months ago) closed on my first property. owner occ duplex. I got a great deal on the thing about 20% below market and used a FHA. After closing on the loan and the couple bigger projects I completed I still have a good amount of cash left! What is the best way to purchase a 2 duplex!? I know there is a regulation stating you need 2 years landlord experience to use rental income to offset mortgage debt, while my income is decent I certainly cant qualify for two mortgages. Ive looked into seller financing a bit... any suggestions on options or should I just stack ca$h for the next two years?!?!?

Thanks!!!!
