Does the Rio Grande Valley have a supply glut of single-family homes? Here’s what we know

There are more homes on the market available for sale in the McAllen-Edinburg-Mission metro area as of June than in the past 36 years.  

That’s more than 3,200 homes for sale in a market that typically sells no more than 400 homes each month. 

If the average pace of home sales continues, it would take upwards of 9 months for the market to sell out of inventory, which means the market leans heavily towards buyers instead of sellers. 

In general, about 6 months of inventory is considered a balanced market, and less than that is a seller’s market. The most recent extreme example in the McAllen metro of a seller’s market was as recently as 2021, when there were just 2 months of inventory available. 

That market gap encouraged a flurry of new subdivision activity across Hidalgo County, with hundreds of new subdivisions and thousands of homes under construction. 

But now, year-over-year sales have slowed to 3.6% between June 2025 and June 2026 — a far cry from a recent peak of 22% growth during the same period between 2020 and 2021.

In the Brownsville-Harlingen metro area, there was a smaller uptick in active listings and new construction during that time frame, with about 1600 homes on the market as of June, roughly the same as in June 2016. 

The Brownsville metro is considered a balanced market with just over 6 months of home inventory and sales were down about 1.1% over the year in June. 

The biggest difference in the past few decades has been the median price of single-family homes, which have increased from about $140,350 in June 2016 to $254,500 in June 2026 in the McAllen metro and jumped from $142,250 in the Brownsville metro in June 2016 to $278,000 in 2026. 

A microcosm of what’s happening can be shown in McAllen. 

There’s a single-family home near 4 Mile Line and North Ware Road in McAllen that was built in 2006 and has been sold three times since 2016. 

The three-bed, two-bath home spanning 1,608 square feet on a 5,589-square-foot lot was sold for an undisclosed price in July 2016. 

Hidalgo County deeds show the homebuyer took out a 30-year mortgage totaling $156,750 from San Antonio-based Security Service Federal Credit Union in 2016. 

That same home was listed by December 2021 for $234,900 and sold by January 2022 for an undisclosed price. If the sale price reflects the public record — that’s a 49% increase in a 5-year span. 

The next homeowner took out a $170,000 loan from AmeriSave Mortgage Corp. in 2022, deeds show. 

In March 2026, the home was listed for sale yet again for $259,900 and sold by July 2026 for an undisclosed amount. 

The third homeowner took out a $250,381 loan underwritten by Mortgage Solutions tied to the sale in 2026. 

That’s a 10% increase in potential sale price over a four-year period, which is a slower rate of appreciation than during the height of the COVID-19 pandemic and could hit about a 12% increase by year 5 for comparison. 

That means the homes which are selling are not increasing in value nearly as rapidly as before. 

Meanwhile, the 30-year-mortgage interest rate back in June 2016 was hovering around 3.57% and the interest rate is now closer to 6.47% in 2026. 

Whether thousands of homes on the market in the McAllen metro mean a supply glut depends on how quickly the population and economy could grow over the next decade, whether the region will continue attracting a higher volume of homebuyers for available jobs — or not.
