Just seven days after I close, I see a huge new TL on my EQ this morning. Since the FICO score calculator predicted I could lose 20 points (or gain 10), I paid $11 to see what it did to my score. It dropped exactly ONE point. It also said my average account was $110k. I like that... So it looks like home ownership is worth enough points to overcome the new installment debt. Didn't hurt my score much and can only get better from here.
