I recently refinanced my mortgage from one where my father was a guarantor to a new one (at a different bank) where he is not on the paperwork. My sister is in the process of purchasing her own apartment and, like he did for me, my dad is going to guarantor her mortgage. The refinance occurred on December 4 and apparently my dad's credit report is still showing the guarantee -- which is causing issues for him to guarantee my sister's mortgage. I assume there is a time lag before it comes off of the credit report, but do people know how long it generally is? I assume he can contact the credit reporting agencies individually with copies of the payoff documents, or alternatively I would imagine the bank providing my sister's loan can use the payoff information to get through underwriting and Fannie Mae. Any advice/insight would be greatly appeciated. [less]
