Basically to answer you question: Pre-foreclosure Homes are not listed as pre-foreclosured. They are properties that could be for sale with a Real Estate Company called (short sales) see my blog on short sales- http://mbarone1.wordpress.com/category/uncategorized/
This would educate you on the short sale process.
The Delaware County courthouse website shows foreclosures upcoming at the Courthouse, Either Sheriff sales or Judicial Sales: http://www.co.delaware.pa.us/sheriff/realestate.html
In addition to working as a Real Estate Broker in the area; I also work for a company who has contracted with a few dozen banks and servicers throughout the country. The objective is to help homeowners with the Obama's administration HAMP program, (Homeowners Affordable Modification Program). Homeowners are given the opportunity (if financially capable) to modify their mortgage loan. In the event homeowners either can't qualify for the HAMP, they will decide to sell the property prior to the foreclosure date. These lenders throughout the US do not wish to foreclose on homeowners since it will cost thousands in legal fees.
It basically starts like this:
This process of foreclosure begins when a homeowner defaults on their loan. Generally when this occurs, the lender involved will issue the homeowner a notice of default, after 60 days (Act 91 notice) and for all intents and purposes this begins the preforeclosure period.
Then from here on out there are many things may happenâ€”the homeowner could and may raise the money to pay off their default debt to the bank or lender and stay in their home,(Modify) (HAMP) their loan to continue make payments to the lender on a 3 month trial period (until they are approved with the (HAMP), OR the lender issues a Notice of Sale (judicial sale) and arranges to put the property up for sale at a later date, (REO) OR the homeowner finds someone willing to buy their home and avoids a foreclosure sale. OR Sell the property if the homeowner is (upside down). (Short Sale)
This last option is becoming increasingly common, as investors and home buyers alike often look to find great homes for sale at extremely low prices through the short sale process.
