From Consumerist.com:
An update to how the new FICO '08 scoring system got revamped this year:
Collection amounts where the original debt was under $100 will be totally disregarded, MarketWatch reports. Back in Feb we reported that they would still be taken into account but only matter less. Also, FICO'08 has been rolled out to all three credit bureaus since last month. Before it was only being tested at one and there was some disagreement over whether all the bureaus would accept it.
However, Freddie Mac and Fannie Mae haven't adopted FICO '08 yet. So if you're getting a traditional conforming mortgage backed by one of them, lenders are still going to judge you under the old FICO system.
