Stuck

Just got this response from my current VA loan lender.
I’ve been back and forth with them another lender trying to get the best possible interest rate for my VA IRRRL streamline refinance. Current rate is 7.25% next offer from competing lender was 6.25%. Then shot that over to current lender seeing if they could beat it and they came up with 6.125%. Sent that over to the competition and they got it down to 5.99% and this is the response from current lender. I’m stuck on what to do. Thanks in advance.

“Our current loan:

6.125%. total cost: A+B+C minus our lender credit on LE= $4,430

Their offer:

5.99. Total cost: A+B+C on their LE= $8,082

You are getting a rate .125 better rate, but paying $3500 more in cost?

I could do the same, but I don’t think it makes sense.”
