Can I Refinance my house after 1 week of buying

[Suneel P.]

I closed my house last week. My current lender says I cannot refinance my loan until 6 payments are made. I want to refinance since my new lender rate is lower and that would save me some money. I had to go with my current lender because they are the preferred lender for our builder. Do you know if there would be a problem if I go ahead and refinance my loan though my current lender asks me to wait until 6 payments?
