There are multiple factors that determine the rate at which your vehicle gets financed. Most customers think that your credit score is the highest influencer of rate, which is only partially correct. A lender will look at many factors that affect your credit score. They look at things such as: down payment, length of financing term, job time, income, time at residence, previous auto loan history, open (still paying) auto loans, debt to income ratio, etc. We would be happy to discuss these things in more detail at your convenience.
Equity is the difference between what your vehicle is currently worth, and the amount of money you still own on the loan. This can be positive or negative. For example, if you owe $12,000 and your vehicle is worth $10,000, then you have $2,000 in negative equity. On the other side, if you owe $10,000 and your vehicle is worth $12,000, then you have $2,000 in positive equity.
The lender determines that, but most often the answer is yes. Make sure you designate the additional money to be applied to the principle of the loan and not the interest.
