Comparing rate offers received on different days
Learn why mortgage rate offers fluctuate and how to effectively compare quotes received on different days to ensure you are getting the best deal.
The short answer
Mortgage interest rates are dynamic and can change daily due to market conditions. When comparing offers received on different dates, you must look at the APR, points, and lender credits within your Loan Estimates, as these components provide a standardized way to measure costs regardless of the specific day the offer was generated.
Understanding Rate Fluctuations
Interest rates are not static. A quote received on Monday may differ from one received on Wednesday because of shifts in the broader market.
Since rates change, it is helpful to ask lenders to provide offers on the same day if possible, though this is not always feasible.
Worksheet Example: Record the date and the specific interest rate for every quote you receive to track how the market impacts your potential costs.
Using APR to Compare Offers
Because rates vary, use the Annual Percentage Rate (APR) to compare the total cost of each loan. The APR includes the interest rate plus other fees, making it a more reliable comparison metric.
If one lender offers a lower rate but has higher origination fees, the APR will reveal which loan is actually cheaper in the long run.
Planning Example: Ask your professional: 'How do the origination charges in this offer affect the final APR compared to my previous offer?'
Points and Lender Credits
Lenders may offer you 'points' to buy down your rate or 'lender credits' to reduce your upfront closing costs. These can mask the true cost of the rate.
Evaluate if paying for points is worth the long-term interest savings or if taking a credit is better for your immediate cash flow.
Planning Example: Ask your professional: 'If I pay for points, how many years will it take for the interest savings to cover the upfront cost?'
The Importance of Rate Locks
A rate lock guarantees your interest rate for a specific period, protecting you from future market volatility. However, not all lenders offer this immediately.
Ask your lender if the rate in your Loan Estimate is locked and what the terms of that lock are. A locked rate is more valuable during volatile periods.
Worksheet Example: Note whether each Loan Estimate includes a 'Yes' or 'No' for rate locks and the duration of that lock.
Checklist
- Record the date and time each mortgage quote was issued.
- Compare the APR of each offer rather than just the interest rate.
- Identify if any points were paid to secure the quoted rate.
- Check if the quoted rate is currently locked or floating.
- Evaluate the impact of lender credits on your total closing costs.
Common questions
Why does my rate offer change every time I talk to my lender?
Interest rates move frequently based on market conditions, so quotes are usually only valid for a short time unless they are officially locked.
How can I compare offers if one lender charges points and another doesn't?
Use the APR metric in your Loan Estimate, as it integrates both the interest rate and the cost of points into a single, comparable figure.
