Ok, so here is the scoop. I live in Phoenix Arizona, I'm 23 and I do fairly well for myself. I have a 2005 BMW 330i that I bought last year and my credit score was terrible back then. Somewhere around 590 or 600. I'm paying a 14.99% interest rate and my payment is 645$. I can easily pay this, but I realize that now, since my credit score(according to Equifax) is now over 700, I could probably get a much better interest rate if I refinanced. I'm not sure if this reduces my Debt to Income ratio. If its calculated on a monthly basis, then it probably would. Most of my accounts on my credit are only from the last couple years, and I have a few already in this last year so I don't really want to go and open a new one all that bad in fear it will hurt my score. In January, My lease will be up on my house(for the 3rd full year) and I plan on purchasing my own. Should I wait till I get my home loan? Or would it be wiser to wait refinance and try to get my DTI down? (I make ~8k/month) Also, if anyone out there could give me a general Idea on how much I might qualify for(as far as dollar amount is concerned) that would be great as well. Thanks! If you need more info from me let me know. To help give you a better idea, the car was purchased for $23,000. My previous car unfortunately was upside down 5k. + tax title etc it was a 31k car loan. Its down to $28000. but now since I drive double the normal milage, the car is now only worth about 18-20k. Does that hinder my ability to refinance? Isn't the most important thing wether i'm able to make the payment? I've been making a 645$ monthly payment with ease and always on time. Its an automatic deduction.
