Chris, these RealtyTrac profiles are somewhat misleading, as they often lead people to think that they are equivalent to listings, available at the dollar amount given on the profile.
All a "pre-foreclosure" listing such as this means is that the borrower is late with a payment. It does not mean that the property is available for sale or will necessarily be available for sale and it certainly does not mean that the property is available for purchase at the dollar amount of the default.
If you want to save time and money, you would be wise to work with a broker who could educate you in this regard and work out a plan for you to acquire whatever it is you have in mind.
