Normal period for contingencies in California

[Bengt Berggreen]

Hi, I am in the middle of selling my house in the LA area and have an offer on the table at a good price. The problem is they are asking for more time, so inspection to be 30 days with loan and appraisal contingency to be 45 days and close to be 90 days!!! Is this a reasonable ask? if not what would be? It's on a $2mln house btw....oh and am working with a realtor that I have done other transactions with in the past, but this sounds sketchy... Thanks
