I am not a pro on foreclosures,but I found some info it. Please read below.
Pennsylvania Foreclosure Laws
In the state of Pennsylvania, all foreclosures must be pursued through judicial proceedings. Before the lender can begin the process of foreclosure, the borrower (homeowner) has to have been in default on a payment for at least 60 days. Once these 60 days have passed, the lender can mail the homeowner a Letter of Intent, detailing the amount owed in default and the lender's intention to foreclose. If the lender does not receive the defaulted payment within 30 days after serving the homeowner with the Letter of Intent, the lender may pursue a court order to foreclose by filing a suit (known in this case as a Lis Pendens).
At this point, the homeowner is notified of the Lis Pendens by mail, and is granted an additional thirty days in which to respond to it by either contesting it in court or paying the amount due. If neither of these instances occur, the court may rule against the homeowner and order that their property be sold. The homeowner retains the right to halt the foreclosure at any point up until one hour before the scheduled sale by paying off the default amount and any additional fees incurred.
At least 30 days before the sale, the county Sheriff delivers a Notice of Sale and delivers a copy of the notice to the homeowner. The Notice of Sale must also be listed weekly in two local newspapers for three weeks before the sale occurs. The sale may be postponed only once, and for a period not to exceed 100 days. The court must approve any other postponements.
The Sheriff conducts the style, which works like a public auction. The property is awarded to the highest bidder and upon receiving payment, the Sheriff transfers ownership to the winning bidder. Under Pennsylvania foreclosure law, the original homeowner retains no right to redemption once the sale is complete.
