If the homes are already foreclosed upon by the banks they'll soon be, of not already, listed on the local Multiple Listing Service (MLS). If by "up for foreclosure" you mean that they are scheduled for auction at the courthouse steps, those are advertised in the local newspaper. But if you are referring to homes in jeopardy of foreclosure (some call that pre-foreclosure status), it gets a little more tricky. All that means is that the homeowners are behind on their payments. There's really no polite way to inquire about something like that of strangers, and a lot of people don't think of it that way at first.
There are some really good deals out there in York County-both foreclosures and ones that aren't. If you'd like some listings sent to you via email without pressure from me or have other questions, please get in touch by either calling, texting or sending me an email.
