It really depends on what you are wanting and the goal of the purchase.

Prepayment penalties are a thing of the past, so dump your bitcoin into paying down the balance (and, possibly, dropping the PMI) after the fact - no one sources where you make your normal monthly mortgage payments from.It's going to be in limbo and a giant "it depends" until such time as someone opens a Bitcoin clearing house that does all the little compliance and PATRIOT Act things that Wells Fargo and Fidelity do, or (more likely) until such time as Fidelity or Wells Fargo adds Bitcoin to their financial service offerings.
