Realty Trac is a teaser site. They want you to pay a subscription and then they will give you information on homes that are having trouble paying their mortgage (in some stage of foreclosure). That is a far cry from available for sale on the market. Work with a realtor directly is you're seriously interested in buying a home.
As is described in other posts, you'll need to take the steps to qualify as a buyer before you get started. That includes getting prequalified for any loan you might need, making sure your credit is strong and that you have the funds for a downpayment. Even though you can buy a home with very little downpayment, there is still some funds required.
This looks to be a preforeclosure or foreclosure that is not currently listed.
However, there are a few active listings on Everest that are available. Should you want more information on those feel free to contact me: Joseph@dickeydrewhomesales.com.
I hope this helps in your home search!
