Miami Luxury Homes are driving key parts of Miami-Dade County’s housing market, even as higher mortgage rates weigh on overall sales. New data from the Miami Association of Realtors shows that ultra-luxury properties and more affordable condominiums continued to attract buyers in September. Meanwhile, sales across the broader market declined compared with the same month last year.
Mortgage rates have remained around 7.5%, their highest level in nearly three years. As a result, borrowing has become more expensive for prospective homeowners. Many buyers are delaying purchases while they assess financing costs and wait for more favorable market conditions.
Miami Luxury Homes Defy Market Weakness
Despite these challenges, Miami-Dade’s luxury housing segment recorded a major milestone. The county surpassed its previous annual record for home sales priced at $30 million or more, achieving the result in just nine months. The earlier record was set in 2025.
By the end of September, Miami-Dade had recorded 24 home sales at or above the $30 million mark. That total already exceeded the 21 transactions recorded across the entire previous year.
The figures highlight the strength of demand at the very top of the market. Although higher borrowing costs have affected many buyers, wealthy purchasers often have the financial resources to complete transactions without taking out a mortgage.
This difference helps explain why Miami’s most expensive properties can continue to sell while other parts of the housing market slow. Buyers who can pay in cash face less direct exposure to mortgage-rate changes. Consequently, the ultra-luxury segment may remain active even when financing conditions discourage other purchasers.
Miami Housing Sales Show a Mixed Picture
The wider Miami-Dade market, however, experienced weaker results. Total home sales fell 2% in September compared with September of the previous year. Single-family home sales recorded a larger decline of 4.7%.
The slowdown followed another annual decrease in August, when total sales were down 1% year over year. Together, the figures suggest that higher financing costs continue to influence purchasing decisions across the county.
Still, the market is not moving in one direction. While overall sales weakened, certain condominium price ranges continued to attract buyers. Existing condo sales increased by just 1% in September compared with the same month last year. However, condominiums priced between $300,000 and $400,000 recorded a stronger annual increase of 14.5%.
This affordable segment offers an important contrast to the broader slowdown. Buyers seeking lower-priced properties may still find opportunities in Miami-Dade, although affordability, building conditions and financing access can vary significantly from one property to another.
Why Miami Luxury Homes Attract Cash Buyers
Cash purchases are a major factor behind the resilience of both ultra-luxury properties and some lower-priced condominiums. Buyers who do not rely on traditional mortgages can avoid many of the immediate effects of rising interest rates.
In the luxury market, affluent purchasers frequently use cash to acquire high-value properties. According to the Miami Association of Realtors, 82% of condominiums priced at $1 million or more were purchased in cash last year.
These transactions help support the high end of Miami-Dade’s real estate market. For wealthy buyers, avoiding mortgage financing can simplify purchases and reduce exposure to changing lending costs. It also allows transactions to proceed without depending on the approval process required for a conventional home loan.
Cash purchases are also common among buyers of existing condominiums priced between $300,000 and $400,000. Many of these properties are located in older buildings, where financing can be more difficult to obtain.
Following the 2021 collapse of Champlain Towers South in Surfside, lenders increased their scrutiny of condominium buildings’ financial and structural condition. As a result, some buildings have faced restrictions that make mortgage approval harder for prospective buyers.
Condominium associations may need to meet stricter standards involving building maintenance, reserves, insurance and structural safety. When a building fails to satisfy a lender’s requirements, buyers may struggle to secure financing even if they can afford the purchase price.
In these cases, cash becomes especially important. Buyers who can complete a transaction without a mortgage may have more options than those who depend on bank approval. This dynamic helps explain why cash activity remains significant in certain lower-priced condominium segments.
Miami-Dade Leads in Cash Home Sales
Miami-Dade relies on cash transactions far more heavily than the national housing market. In September, 38% of home sales in the county were completed in cash. By comparison, the national average stood at 27%.
The Miami metropolitan area also leads the nation in cash sales, according to data from the Miami Association of Realtors. Nearly half of existing condominium transactions and more than one-quarter of single-family home sales in September involved cash purchases.
These figures show how the region’s housing market differs from many other parts of the United States. In markets where buyers depend more heavily on mortgages, higher interest rates can have a stronger impact on affordability and demand. Miami’s large pool of cash purchasers provides a degree of protection for some property segments.
However, cash activity does not mean every part of the local market is insulated from economic pressure. Buyers still consider property prices, insurance expenses, maintenance costs and the long-term value of their investments. Higher mortgage rates can also affect buyers who need financing, limiting demand in areas where cash purchasers are less common.
Foreign Buyers Support Miami’s Housing Market
International demand is another important reason cash transactions play such a large role in Miami-Dade. Foreign nationals represent a significant share of the area’s property buyers, and securing a U.S. mortgage can be more difficult for some overseas purchasers.
Because of these financing challenges, international buyers may choose to purchase properties with cash. This can be particularly relevant in Miami, which attracts overseas purchasers interested in condominiums, new developments and established residential properties.
A report published by the Miami Association of Realtors in July 2025 found that foreign buyers had purchased nearly half of all new-construction, pre-construction and existing condominiums in Miami-Dade during the preceding 18 months.
That level of activity demonstrates the importance of international demand to the county’s condominium market. Foreign purchasers contribute to sales across several property types, including units in developments that are still being planned or built.
Their presence can also influence how the local market responds to changes in U.S. financing conditions. Buyers who rely on cash may continue pursuing properties even when domestic purchasers face higher borrowing costs. Nevertheless, international demand can vary with currency movements, economic conditions and buyers’ investment priorities.
What the Latest Figures Mean for Miami
Miami-Dade’s September results reveal a housing market with sharply different trends across price ranges. Overall home sales declined, and single-family transactions faced additional pressure. At the same time, the county set a new record for homes selling at $30 million or more, while condominiums priced between $300,000 and $400,000 posted stronger annual sales.
Cash purchases help connect these seemingly different outcomes. Wealthy buyers can purchase luxury homes without mortgages, while some buyers of older condominiums turn to cash because financing is difficult to obtain. International purchasers add another source of demand, particularly in the condominium sector.
For the coming months, mortgage rates will remain an important factor for buyers who need financing. Building safety and lending requirements will also continue to shape demand for existing condominiums, especially in older properties.
The latest figures do not point to a uniform recovery or decline. Instead, Miami-Dade’s market is showing how buyer resources, property prices and access to financing can produce very different results within the same region. Luxury homes and selected condominium segments are holding up, even as higher borrowing costs weigh on the wider market.
