Credit Scores directly impact your home loan terms. In fact, both home loan interest rates and mortgage insurance rates (when applicable) decrease as credit scores increase.
Credit Scores and Mortgage Interest Rates
Mortgage lenders use a credit score tier system in order to determine interest rate (other factors such as occupancy also factor into interest rate received). Additionally, mortgage insurance products also factor in credit score. The most common tier system is based on 20 point increments.
