What Is Months of Housing Supply? A Las Vegas Guide

Quick answer: Months of housing supply is how long the homes currently for sale would take to sell if sales kept their current pace and no new listings came on. It is one of the quickest ways to gauge whether buyers or sellers have more room to negotiate, but only if you read it for the right place, the right kind of home and the right time of year.

The national figure you see in headlines and the Southern Nevada figure in monthly local reports are calculated in a similar way, yet they measure different markets. Neither one tells you much about a single street, price range or floor plan on its own. This guide explains the definition, walks through the math with recent Las Vegas figures, and shows how to adjust your reading for geography, property type and seasonality. For broader context, see our October 2026 Las Vegas market update and our comparison of the Las Vegas and national markets.

Months of housing supply at a glance

The Census Bureau defines months' supply for new homes as "the ratio of houses for sale to houses sold," an indication of how long for-sale inventory would last at the current sales rate if no additional houses were built [1]. For existing homes, the National Association of Realtors' series describes it the same way: the months it would take to sell current inventory at the current sales pace. In Southern Nevada, Las Vegas Realtors reported that October 2026's sales pace equated to a nearly six-month supply, compared with just over four and a half months a year earlier [3]. A supply of around six months is a commonly cited rule of thumb for a balanced market [4], though it is a guideline rather than a fixed line. The national and local figures are not like-for-like: they cover different geographies, different listing definitions and, in the national case, a sampled data set.

How do you calculate months of housing supply?

The basic formula is the number of homes for sale at the end of a month divided by the number of homes sold during that month [5]. If an area has 1,000 active listings and 200 sales in a month, it has 1,000 ÷ 200 = 5 months of supply [5].

Here is the same arithmetic with recent Southern Nevada figures. At the end of October 2026, Las Vegas Realtors counted 8,112 single-family homes and 2,837 condos and townhomes listed without offers, and 1,895 existing homes, condos and townhomes sold during the month [3]. Adding the listings gives 10,949, and 10,949 ÷ 1,895 works out to about 5.8 months, in line with the "nearly six-month" supply reported [3]. This is h&e’s illustrative calculation from the counts reported by FOX5, rather than a separately published LVR figure rounded to one decimal place.

Always check which listings a report counts. Some sources count all active listings, while others count only homes listed without offers. The two can produce different results from the same market.

How many months of housing supply does Las Vegas have?

Southern Nevada had nearly six months of housing supply in October 2026, according to Las Vegas Realtors data reported by FOX5 [3]. This regional figure covers existing single-family homes, condos and townhomes. Using the reported inventory listed without offers and October closed sales produces approximately 5.8 months. It does not describe every Las Vegas neighborhood or include a separate measure of new-construction supply.

The calculation uses 10,949 listings without offers divided by 1,895 October sales. Treat it as a dated regional snapshot and compare it with the relevant segment before making a pricing or offer decision.

How does geography change what the number means?

Months of supply describes the area it measures, and nothing smaller. A national figure blends hundreds of local markets. A Southern Nevada figure blends areas such as Henderson, Summerlin, North Las Vegas and the central valley, plus every price range from entry-level condos to luxury estates. Within that blend, one area or price band can have far fewer months of supply than another.

For a real decision, narrow the lens: the specific area, a realistic price band and the home type you are buying or selling. Small samples can swing sharply from month to month, so look at a few months together when the counts are low. You can browse our community guides to compare areas on homes, amenities and drive times.

Why does property type matter?

Single-family homes and condos or townhomes are separate markets with different buyers' budgets, financing considerations and HOA structures. In October 2026, single-family sales in Southern Nevada fell 11.9% from a year earlier while condo and townhome sales fell 23.6%, even though listings without offers rose by a similar share for both (7.6% and 6.7%) [3]. With inventory growing at similar rates, the sharper sales decline suggests a larger year-over-year increase in months of supply for condos and townhomes. A combined figure can hide these differences.

New construction is measured separately too. The Census Bureau publishes its own months' supply for new houses [1], which is not directly comparable with resale figures from Las Vegas Realtors or NAR. Our guide to new construction vs. resale homes in Las Vegas covers the practical differences.

How does seasonality affect months of supply?

The number of homes that sell each month changes through the year, and the number of new listings does too. Because months of supply divides one by the other, it can rise or fall with the calendar even when underlying conditions are steady. Some published series are seasonally adjusted and some are not; the NAR existing-home series shown on FRED, for example, is not seasonally adjusted [2].

The simplest fix is to compare a month with the same month a year earlier, as Las Vegas Realtors does when it contrasts October 2026 (nearly six months) with October 2025 (just over four and a half months) [3]. Then look at the trend over several months rather than one reading.

Does more months of supply mean prices will fall?

Not necessarily. Months of supply describes negotiating conditions, not a price forecast. In October 2026, Southern Nevada's supply rose year over year, yet the median single-family price was $475,000, up 0.1% from a year earlier, while the condo and townhome median was $279,000, down 2.1% [3]. Prices for a specific home depend on its condition, location, price point and how it compares with similar listings. Pair months of supply with other signals, such as the share of homes selling within 60 days, which was 72.4% for single-family homes and 62.5% for condos and townhomes in October 2026 [3].

How huntington & ellis would use months of supply

We start with the published valley-wide figure for context, then pull the numbers for the area, price band and home type that match your goals. We compare them with the same month a year earlier and review how quickly comparable homes are going under contract. For sellers, that shapes list price, preparation and timing. For buyers, it shapes how many homes to tour, how quickly to act and what terms to request. We also review total monthly ownership cost, including mortgage, property taxes, insurance, HOA dues and assessments, utilities and maintenance, and parcel-level details through the Clark County Assessor.

Where should I find the right figure for my search?

Start with the monthly Las Vegas Realtors report for the valley-wide picture, then ask for a custom report filtered to your area, price range and home type. If the number for your segment looks very different from the headline, prioritize a relevant local comparison while checking the sample size and several months of data. A small number of closings can make a neighborhood figure unusually volatile.

The short answer

Months of housing supply equals homes for sale divided by homes sold per month. It shows how long current inventory would last at today's pace, and a figure around six months is often treated as balanced. In Southern Nevada, it reached nearly six months in October 2026 [3]. Read it for your specific area, home type and season, and compare it year over year before drawing conclusions.
