Anyone had this:

VA short sale with Wells Fargo as 1st lien holder. Appraisal done on 10/1/11 and good for 6 months. 5 months and 1 week later we get approval from WF - but says we MUST close by 3/30/12 since appraisal will expire end of March. 

We are rushing to attempt this BUT....we don't have approval from 2nd lien holder (BofA) yet AND they are wanting approx. $3000 more than WF will allow. 

Is it possible to get WF to give some sort of extension without doing a new appraisal at all? We are only talking a few weeks if that - mainly because 3 weeks to close this loan - not to mention waiting on BofA 2nd approval is cutting it close. 

Any suggestions are welcome. I'm actually the buyers agent -but hoping to help LA get some sort of extension.
