Some require you to live in the property a year before renting. 

One potential route is using a FHA 203k loan for the purchase and rehab if you're okay with living in one of the units for a period of time.

Typically a furnished rental will appeal to someone coming to live in an area for a short to mid term period of time.

It has two units, but the house is only a legal one family, looking to possibly purchase it and live in one of the units and rent out the other, one as a Airbnb or just as a regular rental would need to get some kind of financing to make this purchase by being only a legal one family a conventional mortgage I think would be out of the question.

We would be incurring the tenants in one half and would live in the other half ourselves.

@Dexter Florendo Kalai AspacioBuy in the right location where people want to live and rents will continually increase.

Along with personal reasons IE living with tenant. 

But the issue you will have to live with is the fact that you will have to disclose this.

It's a great option for the right investor at the right time in their lives.  

Live under your means and start thinking about investing in Real Estate.In your position the thought of finding a duplex to house hack, live in one side and rent the other.
