I reviewed and signed a final finance approval document on XXXX/XXXX/16. This is for a 30 year home loan with a 15 % down payment. The document includes the interest rate ( 4.625 % ) and points charge ( {$110.00} ). 
I was contacted by phone after they received the signed document and told that the points charge would be over {$2500.00}. I disputed this and was told that they 'd look into it. The next day I was told that the points charge I signed off on was incorrect. I was given an option to pay over {$1600.00} for points if I want to put 15 % down. My other option is to put down 20 % and pay {$590.00} as a points charge. They are willing to deduct {$590.00} if I choose either option. 
I was given an incorrect estimate from the beginning. These numbers are mainly what I used to decide to move forward with the deal. 
I understand that some closing costs can change before signing off, but I already signed a final approval document. I feel that I should pay based on the signed documentation.
