When you’re looking to buy a home in Brevard County, Florida, one of the most critical factors to consider is the mortgage interest rate you’ll be offered. The interest rate can significantly impact your monthly payment and overall mortgage cost.
Here are the five main factors that lenders consider when determining your interest rate:
Credit Score
A strong credit score is crucial for getting a competitive interest rate. The higher your score, the lower your interest rate is likely to be. Lenders use your credit score to assess your risk as a borrower and determine your creditworthiness.
Down Payment
The amount of money you put down on your home can also impact your interest rate. Generally, a larger down payment can result in a lower interest rate. This is because a larger down payment reduces the lender’s risk.
Loan Term
The length of your mortgage term can affect your interest rate. Generally, shorter-term loans (e.g. 15-year mortgages) have lower interest rates than longer-term loans (e.g. 30-year mortgages).
Debt To Income
Your debt-to-income (DTI) ratio is a measure of your monthly debt payments compared to your monthly income. Lenders use your DTI ratio to assess your ability to repay your mortgage. The lower your DTI ratio, the more likely you are to be offered a lower interest rate.
Property Type
The type of property you’re buying can also affect your interest rate. For example, investment properties and condos often have higher interest rates than single-family homes.

What actually determines your mortgage rate
Your rate is not a single published number that everyone gets. Lenders price each loan according to the risk it carries, so two borrowers applying on the same morning can be quoted different rates. These are the factors that move the number.
Your credit score
Most loans use risk-based pricing. Statistically, lower credit scores default more often, so they cost more to finance. On a conventional conforming loan, roughly every 20 points below 740 can add cost — sometimes as a higher interest rate, sometimes as higher fees, sometimes both. The exact adjustment varies by loan type, which is why a VA loan and a conventional loan can respond very differently to the same score.
Your down payment
More money down generally means a lower rate, because the lender’s exposure is smaller. It also determines whether mortgage insurance applies. See how much you actually need for a down payment.
Your loan program
VA, FHA, conventional and jumbo loans are priced on separate schedules. A veteran comparing a VA loan against a conventional loan is comparing two different pricing models, not two versions of the same one.
How long you lock the rate
A rate lock holds your interest rate and fees for a set window while your loan is processed. The standard lock at Morgan Financial runs 30–45 days, which covers most purchase timelines. Longer locks cost more — the lender is taking on more risk by holding a price further into the future, and that shows up as a higher rate, higher fees, or both.
You may need a longer lock if you’re buying new construction, closing on an extended timeline, or waiting on a contingency. We offer several extended lock options; ask your Loan Originator which fits your contract date rather than defaulting to the standard window.
What you can and can’t control
Market conditions set the baseline and are outside anyone’s control. What you can influence is your credit position, your down payment, your program choice, and how long you need the rate held. Those four are where a conversation with a lender actually changes your number.
