Here is my situation: My credit card utilization is always <6%, 1 month ago i had a auto loan for 17,000$ . My credit score at that point were Fico8 (equifax- 716, experian-720, transunion – 710). I refinanced my auto loan(as apr was coming down from 4 to 1.7%) with my current loan balance 27,000(i took 10,000$ out ) . As a result of auto loan refinance my scores plunged by -17 points , currently my fico8 scores are 694 equifax, 689 experian.
If i reduce my loan balance to 22,000$ (by paying back 5,000$ ) what are the chances that my score reaches 700 points ? Any ideas to improve my score before feb 2016(i am closing on my house in feb) .
