Mortgage rates are set nationally, not by community, so a Sun City Grand buyer gets the same market rate as anyone else with the same profile. What changes your payment is the rate, the price and your down payment. Here is the current picture and a calculator so you can see your own number.
Where rates stand today

This is an average of what lenders offered across the country. Your rate can be higher or lower. A strong credit score, a larger down payment and paying points all move it.
What it does to a Sun City Grand payment
Here is a $435,000 home with 20 percent down, which is a $348,000 loan on a 30 year term. A $435,000 price is near the middle of published Sun City Grand estimates, so it is a fair example.
| Rate | Monthly principal and interest | Compared with 6.27 percent |
|---|---|---|
| 6.27 percent (a year ago) | $2,147 | Baseline |
| 6.75 percent | $2,257 | $110 more |
| 7.00 percent | $2,315 | $168 more |
| 7.40 percent (today) | $2,409 | $262 more |
| 7.75 percent | $2,493 | $346 more |
Estimate your monthly payment
Move the sliders. The rate starts at the October 15, 2026 Freddie Mac average of 7.40 percent.
Principal and interest only. It leaves out property tax, homeowners insurance and the HOA assessment, and it is not a loan offer.

What moves your own rate
- Credit score. A higher score usually earns a lower rate.
- Down payment. More down means a smaller loan and often a better rate.
- Loan type. A 15 year loan usually has a lower rate than a 30 year loan but a higher payment.
- Points. You can pay extra at closing to lower the rate.
- Rate locks. A lock protects your rate for a set time while you close.
Sun City Grand details lenders count
Lenders add the HOA assessment to your monthly costs when they decide how much you can borrow. The Grand lists an annual assessment of $1,976 for July 2026 to June 2027, about $165 a month. See What Are the HOA Fees for Sun City Grand? for every fee.
You also need money for taxes, insurance and the one time fees at closing. A full budget is in the Buyers Guide.
How to find your real rate
- Check your credit report and fix any errors.
- Ask two or three lenders for a written Loan Estimate on the same day.
- Compare the rate, the points and the fees, not only the rate.
- Lock your rate when you have a signed contract.
Frequently asked questions
Common questions
Is there a special mortgage rate for Sun City Grand?
No. Rates are set by the lender based on you and the loan, not by the community.
Where does the 7.40 percent figure come from?
It is the weekly average from Freddie Mac’s survey released October 15, 2026. It is a national average, not a quote.
Does the HOA fee affect my mortgage?
Lenders count the assessment as part of your monthly costs when they decide how much you can borrow.
Should I wait for rates to fall?
Nobody can promise where rates go. If you find the right home, you can ask the seller for help with your rate and refinance later if rates drop.
Can I buy with cash instead?
Yes, many people do. Cash buyers skip the rate and often close faster. Call Deah at (425) 407-2800 to talk through your options.
