Personal factors such as your credit score, down payment, and occupancy can affect mortgage rates. A high credit score indicates less risk to lenders, making you more attractive for loan approval. Down payment amount showcases your investment in the home, with a larger down payment indicating less risk to the lender. Lastly, whether the home is your primary residence, a second home, or an investment property can impact mortgage rates. Generally, rates are lower for primary residences as you are less likely to default on your mortgage.
