Best Way To Finance This

Hello there,

I am considering buying a loft. It was an old warehouse converted into 12 nice condos.

Anyways, the units are zoned both residential and commercial. Currently, if I bought one, I would be the first commercial. I want to put my office in there.

What are my financing options here? Do I have to go commercial or is there a way to take a home mortgage out? I do own my own home now and have equity in it, but not enough to cover the cost of the loft.

thanks.
