How to Finance Mixed Use Building as Primary Residence / Office

[Jason Haynes]

I'm looking at a property that's zoned for mixed use. It has two apartments that are set up to live in. It also has a commercial office area downstairs that is currently leased out. We are considering purchasing this property, living upstairs and using the bottom as an event space or coworking space. I've talked to both of my lenders (residential and commercial) and neither seems to be able to take the loan on. 

Does anyone know what type of loan I would be looking for? Or if it's possible to split it into two loans (one standard residential and the other more of a commercial loan)? Any input would be appreciated.
