( CNN ) -- Tracy Orr sat in the back of the room and prepared to watch her foreclosed home go up for auction this past Saturday . That 's when a pesky stranger sat down beside her and struck up a conversation . Tracy Orr faced losing her home to foreclosure when Marilyn Mock , a stranger , stepped in to buy it . `` Are you here to buy a house ? '' Marilyn Mock said . Orr could n't hold it in . The tears flowed . She pointed to the auction brochure at a home that did n't have a picture . `` That 's my house , '' she said . Within moments , the four-bedroom , two-bath home in Pottsboro , Texas , went up for sale . People up front began casting their bids . The home that Orr purchased in September 2004 was slipping away . She stood and moved toward the crowd . Behind her , Mock got into the action . `` She did n't know I was doing it , '' Mock says . `` I just kept asking her if [ her home ] was worth it , and she just kept crying . She probably thought I was crazy , 'Why does this woman keep asking me that ? ' `` Mock says she bought the home for about $ 30,000 . That 's when Mock did what most bidders at a foreclosure auction never do . Watch why a woman would buy back a stranger 's home » . `` She said , ' I did this for you . I 'm doing this for you , ' `` Orr says . `` When it was all done , I was just in shock . '' `` I thought maybe her and her husband do these types of things to buy them and turn them . She said , 'No , you just look like you needed a friend . ' `` `` All this happened within like 5 minutes . She never even asked me my name . She did n't ask me my financial situation . She had no idea what [ the house ] looked like . She just did it out of the graciousness of her heart , just a 'Good Samaritan , ' `` Orr says . `` It 's amazing . '' Orr says she had taken out a mortgage of $ 80,000 in 2004 when she first bought the home . At the time , she says she worked for the U.S . Postal Service . But she lost her job a month after taking out the loan when she says the Post Office fired her over a DWI while off-duty . She says a wrongful termination lawsuit is pending . Without a job , she fell behind on her home payments . She sold some property in 2006 for $ 12,000 and paid it to the mortgage company , thinking she had done enough to save herself from foreclosure -- but to no avail , she says . `` It 's just been a bad deal , '' says Orr , who now works at All Saints Camp and Conference Center , a Christian group with ties to the Episcopal Diocese of Dallas , Texas . With the foreclosure auction approaching , she planned to make the nearly 80-mile drive to Dallas this past Saturday with an investor friend . But she says he ditched her at the last-minute . She went to the auction with her family , and suddenly found herself in the back with Mock . `` I always talk to everyone around me , '' Mock says . `` I mean you can always find out all kinds of interesting things when you talk to people around you . So I just asked her , 'Are you here to buy a house ? ' `` Mock , who is known as the `` Rock Lady '' for her small business selling flagstone and other rocks in Rockwall , Texas , says she went to the auction with her 27-year-old son to help him buy his first home . He bought his home , and soon afterward Mock came across Orr . Mock says she 's using one of her business dump trucks as collateral for the $ 30,000 sale price . `` I ca n't afford to just give [ the house ] to her , '' she says . As for Orr 's payments , Mock says , `` We 'll just figure out however much she can pay on it . That way , she can have her house back . '' Why be so generous ? `` She was just so sad . You put yourself in their situation and you realize you just got to do something , '' says Mock , who says she has trouble walking by homeless people on the street and not helping them out . `` If it was you , you 'd want somebody to stop and help you . '' When she told her husband of 30 years that she 'd just bought a home for a stranger , she says his reaction was : `` Whatever . '' `` He 's used to it , '' she says with a booming laugh . Mock says she 's excited for another reason too . Orr 's house is located near a Texas fishing hot-spot . `` She says I can come up there and fish , and I love to fish ! '' Orr , who nearly lost her home , says her newfound friend has `` given me back faith and hope to keep going and hold my head up . '' `` Things happen for a reason , '' Orr says .
