Can you give me loan feedback?

I'm buying my first house, would love some advice on whether or not we're doing the right thing.

Key Details:

  1. Down Payment: $275K
  2. Loan Amount: $1,100,000
  3. Loan Term: 30 years
  4. Interest Rate: 6.625% (7 year Adjustable Rate)
  5. Estimated Closing Costs: $111,851
  6. Estimated Cash to Close: $104,606
    1. Loan Origination Charges: $1,530

We locked our rate about a month ago and we're closing in 2 weeks, so I don't have time to reapply for a new rate, should I delay the closing and reapply or should I keep things moving? I'm inclined to close now and then refinance.

We both have excellent credit, and hour HHI is about $450k.

Thoughts?
