According to the Miami Association of Realtors, luxury home sales in Miami posted double-digit gains while existing condominium transactions surged year-over-year in December 2017.

Luxury ($1 million-and-above) existing Miami condo sales jumped 47.6 percent year-over-year, from 42 to 62. Luxury Miami single-family home sales rose 16.7 percent, from 60 to 70. Existing Miami condo sales increased 6.5 percent year-over-year in December, while single-family transactions stayed effectively even (down 0.7 percent).

"Strong pent-up demand for Miami luxury single-family and condominiums fueled December's strong home sales," said George Jalil, a Miami broker and the 2018 MIAMI chairman of the board. "Luxury sellers are becoming more realistic with their asking prices, and buyers are coming off the sidelines. Federal tax reform is also starting to have an impact as more Northeastern buyers are opting to purchase in Miami to escape the higher taxes they could face in states like New York and New Jersey."

Federal tax reform, which was signed into law Dec. 22, 2017, sets a deductions cap for income, sales and property taxes at $10,000. The new cap could lead more residents of states with high property values and state income tax to purchase properties in states such as Florida, which has no state income tax and a pro-business tax structure.

Total Miami Home Sales, Dollar Volume Increase in December

Total existing Miami-Dade County residential sales -- which posted a record year in 2013 and near record years in 2014 and 2015 -- increased 2.9 percent year-over-year from 2,156 to 2,219.

Miami existing condo sales -- which are competing with one of the most robust new construction markets in the country -- increased 6.5 percent year-over-year, from 1,084 to 1,154. Single-family home sales decreased 0.7 percent, from 1,072 to 1,065.

Lack of access to mortgage loans continues to inhibit further growth of the existing condominium market. Of the 9,307 condominium buildings in Miami-Dade and Broward counties, only 12 are approved for Federal Housing Administration loans, down from 29 last year, according to Florida Department of Business and Professional Regulation and FHA.

Total sales volume for all properties accounted for $983.5 million last month, up 23.2% from $797.9 million a year ago. Sales don't include Miami's multi-billion dollar new construction condo market.

Miami's Cash Buyers Represent about Double the National Figure 

Miami cash transactions comprised 39.3 percent of December total closed sales, compared to 42.4 percent last year. Miami cash transactions are about double the national figure (20 percent).

Miami's high percentage of cash sales reflects South Florida's ability to attract a diverse number of international home buyers, who tend to purchase properties in all cash. Miami has a higher percent of cash sales for condos due to lack of financing approvals for buildings.

Condominiums comprise a large portion of Miami's cash purchases as 53 percent of condo closings were made in cash in December compared to 24.5 percent of single-family home sales.

Seller's Market for Single-Family Homes, Supply Declines in December 2017

Inventory of single-family homes decreased 4.0 percent in December from 6,218 active listings last year to 5,969 last month. Condominium inventory increased 3.8 percent to 14,436 from 14,984 listings during the same period in 2016.

Monthly supply of inventory for single-family homes decreased 1.8 percent to 5.6 months, which indicates a seller's market. Existing condominiums have a 13.7-month supply, which indicates a buyer's market. A balanced market between buyers and sellers offers between six and nine months supply of inventory.

Total active listings at the end of December increased 1.4 percent year-over-year, from 20,654 to 20,953. Active listings remain about 60 percent below 2008 levels when sales bottomed.
