extension of foreclosure sale?

[Nicole Togwe]

Hi, I am interested in a house that went to Sheriff's sale and bought back by the bank. It was a judicial foreclosure but the redemption period is likely 90 days. The house is currently on the market for crazy price (over market value.) My question is this.... The owner refused my offer (I am thinking of re-offering) because he thinks he can get more. I guess his confidence is his lawyer told him if he has a buyer before this redemption period ends, he can likely get an extension..... How often is that granted and how many days before the redemption runs out do you need to go to the judge to apply? Just trying to figure out when I should make my next offer and how much. :)
