Home Visit Mortgage Advisor? Is this right?

Hi there!

I have just spoken to a mortgage advisor recommended by our new build developer. He states that he does not have an office, and does mortgage applications over the phone or can visit us in our home.

Question is I've never heard of this, is it ok? Or would we be better going for another advisor, that hasn't been recommend by the new build developer, and works within an office?

Any advice would be appreciated!

Thanks
