VA Refinance on Primary Residence

[Kevin Christensen]

I bought my primary residence with a 5.0% interest rate VA jumbo loan 8/2018. I am getting offers to refinance at 2.75%. My credit has dramatically improved since last year. Loan is $505k. Never done a refi on my primary before. Is it worth it to refi already? I know I'll save tons long term. Is there anything special I should ask? Any lender I should target to do a VA jumbo refi?

Thanks.
