Lender comparison
Rocket Mortgage vs Flagstar Bank

For most vanilla purchases the pricing is competitive either way, so the real question is how you want to work — online and fast, or across a desk from a loan officer.

Flagstar. It's one of the few large banks that writes one-close construction-to-permanent loans, and it lists Construction among its products. Rocket's lineup (Conventional, FHA, VA, Jumbo, HELOC, Refinance) does not include construction financing, so for a build, Flagstar is the natural fit.
Can I get in-person help from Rocket or Flagstar?
Flagstar has physical branches across Lower Michigan where a loan officer will sit down with you. Rocket is fully digital by design with no branches for face-to-face closings, though it offers Detroit-based support with extended evening hours if you prefer to keep everything online.
