Given the importance of maintaining high scores, FICO senior scientist Frederic Huynh agreed to run through the key rules governing how inquiries affect homebuyers and mortgage applicants in an interview with me and in a post on Fair Isaac’s Banking Analytics blog.
Start with the basics: Yes, racking up large numbers of inquiries can lower your score. The FICO models consider such numbers significant because extensive behavioral research has shown that “consumers who are seeking new credit accounts are riskier,” more prone to defaults, according to Huynh. “Statistically, people with six or more inquiries on their credit reports can be up to eight times more likely to declare bankruptcy than people with no inquiries on their reports,” he said. So inquiries do matter.
But this doesn’t mean you’re going to be hit with six separate inquiries and have your score lowered if you’re shopping for a home loan or refinancing and six lenders pull your credit reports. The FICO models, says Huynh, ignore all mortgage-related inquiries during the 30 days immediately preceding the computation of the score. All mortgage inquiries during the 45 days preceding your loan application count as no more than a single inquiry. The same buffer zones cover shopping for auto loans and student loans — but no other forms of credit.
In any event, says Huynh, a single inquiry usually is not a big deal, knocking less than five points off your score. But experts in the credit-reporting field say that despite FICO’s good intentions, bad things can happen with inquiries. This is especially true for people with “thin” credit files, such as young, first-time homebuyers and others without extensive credit histories.
Larry Nelson, owner of KCB Information Services in Pekin, Ill., a credit-reporting agency active in the mortgage field, says a recent applicant lost her preapproved home loan at closing because five new inquiries for an auto loan suddenly appeared on her credit reports. This deflated her FICO score to 610 — a loss of 30 points that put her below the minimum score required for the mortgage.
How could this happen, since auto loans are one of the three protected classes of credit where multiple inquiries within a short period are okay? According to Nelson, unless loan officers properly code the purpose of the inquiry — in this case, an auto loan — when they report it to the national credit bureaus, it may not be identified in credit files that way.
Nelson’s homebuyer had double bad luck: None of the inquiries that should have been covered by the 30-day buffer carried the correct purpose identification. Also, Fannie Mae and Freddie Mac have begun requiring lenders to pull a second set of credit reports immediately before closing to ensure that applicants’ FICO scores haven’t changed significantly. In this case, there was a sudden spike of score-injuring inquiries in the bureaus’ files, and the buyer couldn’t close on the loan.
Nelson says glitches like this “are becoming more commonplace” and can hurt unwary consumers. He strongly urges mortgage applicants to avoid all credit-related shopping — for credit cards, furniture, home improvements, you name it — in the weeks before their closing because a string of inquiries can mount up and knock the home purchase off track or delay it.
Of course, not all inquiries indicate active credit-seeking, says Huynh, even though your files are accessed. For example, if you’re checking on your credit before applying for a mortgage — either through www.
annualcreditreport.com, where they are free once a year, or by buying them from Equifax, Experian or TransUnion — your FICO score goes untouched.
