Financing when moving on to second house hack

[Logan Judnick]

Lets say I purchase a duplex with 3.5% down FHA and live in it for a year as to qualify it as a primary residence. Can I then purchase another multifamily with a 3.5% down FHA loan, or do I have to refinance into a conventional loan on the first property to be able to purchase the second with an FHA loan?

My plan was to keep buying multifamily' s every year or every other year with FHA loans but it seems I may have overlooked the above. Any advice on how to accomplish this without large down payments would be appreciated.

Thank you for your input and advice
