Two builder offers in Surprise this month advertise a lower mortgage rate. Toll Brothers' Sterling Grove is offering a 5.49% 30-year fixed rate, 5.76% APR, on select homes during an event that runs November 7 through 22, 2026. A few miles away in Prasada, DRB Homes' Sycamore Farms page advertises a "Special 3.99% Rate Promotion." Freddie Mac's national average for a 30-year fixed was 7.18% for the week of November 5, 2026.
The two offers are different products. The lower number needs the closer read.
The 3.99% is a five-year rate on an adjustable loan
DRB's Phoenix-area disclosure describes the 3.99% as the initial rate on a 30-year FHA or VA 5/1 adjustable-rate mortgage, with a 6.63% APR. Its example uses a $526,990 purchase price, a $517,444 loan amount, and a minimum 660 credit score. That works out to an estimated principal-and-interest payment of $2,467.37 a month for the first five years. Mortgage insurance, property taxes and homeowners insurance are extra.
Starting in month 65, the rate can adjust every 12 months. The new rate is set at the 1-Year U.S. Treasury Index plus a 1.75% margin. Each adjustment is capped at one percentage point, and the rate can never go above 8.99%. The disclosure also says where the discount comes from. The promotional rate is "available through applicable seller paid rate buydown."
The seller is paying for the rate. The money that pays for a buydown could also have come off the price, and DRB says so in its own terms.
| Offer | What it is | Window | Fine print |
|---|---|---|---|
| Toll Brothers, Sterling Grove | 5.49% 30-year fixed, 5.76% APR | November 7–22, 2026 | Select homes only. The community showed 36 quick-move-in homes from $390,000 to $1.9 million |
| DRB Homes, Sycamore Farms in Prasada | 3.99% initial rate | No Sycamore-specific end date posted | DRB's disclosure ties it to an FHA/VA 5/1 ARM that adjusts after year five, capped at 8.99%. Plans listed from $487,990 to $619,990 |
| DRB Homes, Surprise City Center | Up to $30,000 "Flex Cash" | Contracts signed October 1 to December 31, 2026 | Can go to closing costs, design options, permanent points, a temporary payment buydown, a price reduction, or a mix |
The Flex Cash terms make the point plainly. The buyer chooses whether the same dollars cut the price or cut the rate. To get the incentive, the buyer has to use DRB's approved lender, CMG Mortgage, and its approved settlement agent, Fidelity National Title. The disclosure also says buyers are under no obligation to choose either one. The incentive can't be combined with other offers, and any unused amount isn't paid out in cash.
Why Surprise's price figures look steady
The Phoenix REALTORS report for Surprise single-family homes in October 2026 shows a median sales price of $430,000, up 1.8% from October 2025. Sellers received 98.3% of list price on average. The same report also shows how much the market slowed in October 2026:
- Pending sales fell to 182, down 37.0% year over year
- Closed sales fell to 243, down 21.1%
- Inventory rose to 1,424 homes, up 10.8%
- Months of supply reached 4.7
- Median days on market held at 81
Prices barely moved while contracts dropped by more than a third. The concession line explains the gap. The 98.3% list-price figure leaves out sale concessions and down-payment assistance. A seller who holds the price and pays toward the buyer's rate or closing costs shows up in this report as a near-full-price sale.
Valley-wide data shows how common that has become. Tina Tamboer, senior Valley housing analyst for The Cromford Report, said 59% of Valley home sales in August 2026 involved seller concessions. That was the highest share in the series Cromford tracks. In the $350,000-to-$400,000 range, the share was 71%, according to the Queen Creek Tribune. Tamboer also said much of the sales weakness was concentrated between $300,000 and $800,000. Surprise's $430,000 median falls inside that band.
The metro-wide numbers show the same pattern for new homes. ARMLS data for the 12 months through October 2026 puts the median at $455,990 for new construction and $468,000 for previously owned homes. New homes sold at 98.7% of their most recent list price, and resale homes at 97.8%. Neither figure counts concessions. New construction made up roughly 17% of pending sales over that period. The two medians are about $12,000 apart, and neither one shows what the seller paid toward the buyer's loan.
The pressure comes from the rate
ABC15 reported on October 2, 2026 that the average 30-year fixed rate had jumped to 7.3% that week, its highest level since November 2023. The same story said Surprise builders were marketing rate buydowns and closing-cost help while thousands of homes were under construction or planned in northwest Surprise. Freddie Mac's average has eased a little since then, from 7.32% on October 22 to 7.24% on October 29 and 7.18% on November 5.
When the rate is what blocks a sale, a dollar spent lowering the rate does more for the buyer's monthly payment than the same dollar taken off the price. Builders know this, so they lead with the rate. AZ Big Media reported on November 7 that metro Phoenix buyers now have more room to negotiate on price, closing costs and repairs.
A resale seller can fund a buydown too, within loan-program caps
Any seller can contribute toward a buyer's loan. Each loan program caps how much.
- Conventional loans. Fannie Mae and Freddie Mac cap financing concessions for a primary residence or second home at 3% above 90% loan-to-value, 6% from 75.01% to 90%, and 9% at 75% or below. The cap is 2% for an investment property. Fannie Mae counts the cost of a seller-funded permanent or temporary buydown toward that cap.
- FHA loans. HUD's Handbook 4000.1 allows interested parties to contribute up to 6% of the sales price, and that 6% includes permanent and temporary buydowns.
- VA loans. VA allows seller credits for customary closing costs, including discount points, with no dollar cap. Seller concessions are capped separately at 4% of the home's reasonable value.
On a home at Surprise's October median of $430,000, a 3% conventional cap works out to $12,900. Bankrate's September 2026 explainer says one discount point generally costs 1% of the loan amount and typically lowers the rate by about a quarter of a percentage point for the life of the loan, though lender pricing varies. A temporary 3-2-1 buydown cuts the rate by three points in year one, two in year two, and one in year three, then returns to the full rate. A resale seller can match a builder's monthly payment for the first few years. Matching a lower rate for 30 years usually costs a good deal more. That is why a fixed-rate offer like Sterling Grove's is worth more than its headline gap from the market rate suggests. The ARM is still the cheapest of these options for the first five years.
All of this is general information, not legal, tax or financial advice. Confirm the limits that apply to your loan with your lender before you build an offer around them.
How to compare a new-home offer with a resale offer
- Match the loan product first. Compare a 30-year fixed to a 30-year fixed. If one offer is a 5/1 ARM, look up its margin, its adjustment caps and its lifetime cap. For DRB's ARM those are 1.75%, one point per adjustment and 8.99%.
- Compare payments over the years you expect to own the home. A temporary buydown or a five-year ARM makes the early years cheap. A permanent buydown lowers the payment for the whole loan.
- Price the strings. Lender and title requirements, design-center credits that can't be paid out in cash, and offers limited to "select homes" all change what the incentive is worth to you.
- Ask the resale seller for the same dollars. A seller paying toward your rate or closing costs is spending money that could have come off the price. That keeps the reported price high while you get the discount in another form.
- Read the report figures as list price, not net. Surprise's 98.3% for October 2026 measures sale price against list price, before concessions.
Quick answers
Does 98.3% of list price mean Surprise sellers aren't negotiating? No. That figure leaves out concessions, and Valley-wide concessions reached 59% of sales in August 2026.
Does the Sterling Grove rate apply to every home there? Toll Brothers advertises it for select homes during the November 7–22 event. Ask which homes qualify.
Can a seller pay points on a VA loan? VA treats discount points as a closing cost that sellers can credit with no dollar cap. Its separate 4% cap applies to concessions.
If you're deciding between a Surprise new build with a rate offer and a resale home where the seller might pay toward your loan, send me both. I'll lay them side by side on monthly payment, loan type and fine print so you can see which one costs less. Laura Lee Cahal. Let's Connect.
