Loan needed to revamp a commercial building / apartments

[Ryan Rush]

This is likely a stupid question, but I’ve never done it before. I have a commercial building in a downtown area. I want to remodel it and add two apartments in usable space inside, as well as remodel an apartment I already have to use as an Air bnb (since another apartment in this building is doing so well as one).

I have a very good credit score, as well as considerable equity in the building as well as another house I own free and clear. The building is on a strange loan though- it was bought as a package deal with another house, so I’m not sure how that’s figured out.

Where do I start?
