Real Estate Markets With the Lowest Vacancy Rates in 2026: Where Supply Cannot Keep Up

In real estate investing, vacancy is the variable that turns a positive cash flow model into a negative one. A market with 3% vacancy behaves differently from one with 10% vacancy: the 3% market allows landlords to raise rents, select tenants, and expect rapid re-leasing. The 10% market puts negotiating power in the hands of renters and erodes the income model.

The five markets that show the tightest supply signals in the PropertyIQ dataset as of February 2026 are Rochester, NY (PropertyIQ Score 99/100), Syracuse, NY (96/100), Springfield, MA (97/100), Grand Rapids, MI (93/100), and Akron, OH (88/100).

All data in this post is effective as of February 28, 2026, and is pulled live from the PropertyIQ MCP server.

How PropertyIQ Measures Vacancy Signals

The PropertyIQ index does not track direct rental vacancy surveys. Instead, it uses market-level supply and demand data as proxies for vacancy pressure. These proxies are more current than annual survey data and capture real-time shifts that Census and BLS figures lag by 12 to 18 months.

The key metrics that signal low vacancy conditions:

Pending ratio: Pending contracts divided by active listings. A ratio above 1.0 means more contracts in process than homes available to buy. This is the most direct signal of supply shortfall. When buyers cannot find homes to purchase, renters who want to become buyers stay in rental units longer. Supply shortfall in the for-sale market compresses the rental vacancy rate.

Supply score: The PropertyIQ model's composite measure of how constrained listing supply is relative to demand. Scores above 85 indicate significant supply shortage.

New listings growth (YoY): Declining new listings in a market means the pipeline is not replenishing. When fewer homes come to market for sale and for rent, vacancy tightens.

Days on market: Fast absorption means available units are claimed quickly. Low DOM in the sale market reflects a pattern that typically extends to the rental market.

Sale to list ratio: Markets where buyers pay above asking are markets where demand has outrun supply. That same structural dynamic applies to rents.

#1 Syracuse, NY: 96/100 -- Pending Ratio 2.0, Listings Declining

PropertyIQ Score: 96/100 (A) Listing price: $289,900 (Realtor.com, March 2026) Zillow home value: $246,073 (January 31, 2026) Pending ratio: 2.006 New listings YoY: -6.52% Supply score: 29.8 (Realtor.com hotness score; see note below) Demand score: 87.3 Days on market: 60 Sale to list: 101.3% (November 2025) Zillow 12-month forecast: +4.5% (December 2025) Unemployment: 3.7% (November 2025)

Syracuse has the highest pending ratio in this analysis: 2.006. That means for every 100 homes actively listed for sale, more than 200 purchase contracts are pending. Demand is running at more than twice the available supply.

New listings are down 6.52% year over year as of March 2026. The supply pipeline is contracting while the demand pipeline expands. When fewer homes come to market and buyers are already outnumbering available listings by a 2:1 margin, the feedback effect on the rental market is direct: would-be buyers cannot find homes to purchase and remain in rental units, compressing rental vacancy.

The 60-day average DOM may seem slow relative to some of the other markets on this list, but it reflects a market where the listing price is often set high initially, requiring repositioning before contracts are written. The sale-to-list ratio of 101.3% confirms that once price is calibrated, buyers pay above asking.

Five-year home value appreciation in Syracuse is 43.23% as of March 2026, the highest on this list. The Zillow 12-month forward forecast of +4.5% is also the highest in this report.

For rental investors, Syracuse's concentration of anchor institutions reduces vacancy risk. Syracuse University employs over 8,000 people and generates a permanent population of students, faculty, and staff who rent across the metro. Upstate Medical University adds another institutional anchor. These institutions do not contract during rate cycles or economic slowdowns.

#2 Rochester, NY: 99/100 -- Pending Ratio 1.88, Buyers Pay 108% of Ask

PropertyIQ Score: 99/100 (A+) Listing price: $298,950 (Realtor.com, March 2026) Zillow home value: $264,121 (January 31, 2026) Pending ratio: 1.882 New listings YoY: 0.0% Supply score: 97.0 Demand score: 93.0 Days on market: 31 Sale to list: 108.5% (November 2025) Zillow 12-month forecast: +4.3% (December 2025) Unemployment: 3.8% (November 2025)

Rochester's supply score of 97 out of 100 means inventory conditions are among the tightest in the country. New listings are flat year over year: the pipeline is not growing. With a pending ratio of 1.88 and buyers closing at 108.5% of list price, Rochester's for-sale market is running in a structural deficit.

31 days on market is the fastest absorption rate of any market in this report. The supply and demand scores (97 and 93 respectively) are near the index ceiling. A PropertyIQ Score of 99/100 reflects these conditions in the composite.

For rental investors: when buyers are outbidding each other by 8.5% above asking price to leave the rental market and become owners, the pool of qualified renters is staying larger longer. The median income of $74,438 against an income-to-buy of $79,393 means many Rochester residents are close to but not quite at the ownership threshold. That population rents, and they need quality housing.

The Zillow rent index is $1,499 per month as of December 31, 2025. At a Zillow home value of $264,121, the gross rent yield on a median purchase is approximately 6.8% before expenses. That is competitive for an A+ market.

The university-hospital complex (University of Rochester, Rochester Institute of Technology, Strong Memorial Hospital) provides institutional demand that does not fluctuate with mortgage rate cycles.

#3 Springfield, MA: 97/100 -- Demand Score 99.7, Inventory Barely Moving

PropertyIQ Score: 97/100 (A+) Listing price: $352,475 (Realtor.com, March 2026) Zillow home value: $356,786 (January 31, 2026) For sale inventory: 344 listings for a metro of 462,000 Demand score: 99.7 out of 100 Supply score: 96.0 Days on market: 32 Sale to list: 100.1% (November 2025) Zillow 12-month forecast: +3.3% (December 2025) Unemployment: 5.5% (November 2025) Home value YoY: +6.84%

Springfield's demand score of 99.7 out of 100 places it at the ceiling of the PropertyIQ model's demand measurement. The supply score of 96 confirms that the available inventory is severely constrained. With only 344 active listings across a metro area of 462,000 residents, the per-capita listing count is among the lowest in the dataset.

Days on market of 32 is the second-fastest absorption on this list. Homes priced correctly in Springfield are not sitting. The market clears in roughly one month.

Home values are up 6.84% year over year as of March 2026. The Zillow rent index is $1,880 per month as of December 31, 2025, reflecting the elevated price point relative to the other markets in this report. Springfield's proximity to Hartford and the I-91 corridor keeps it connected to a larger economic zone than the metro statistics alone suggest.

The note on Springfield: the unemployment rate of 5.5% as of November 2025 is the highest in this report. That is a real risk factor for rental income stability. Landlords in Springfield should weight tenant screening more heavily and maintain higher reserves than in markets with sub-4% unemployment. The strong demand score reflects that even at 5.5% unemployment, buyer and renter demand is running near the index ceiling because supply is so constrained.

#4 Grand Rapids, MI: 93/100 -- Inventory Shrinking, New Listings Falling

PropertyIQ Score: 93/100 (A) Listing price: $404,900 (Realtor.com, March 2026) Zillow home value: $342,610 (January 31, 2026) Inventory YoY: -3.17% New listings YoY: -8.5% Pending ratio: 0.992 Days on market: 44 Sale to list: 99.8% (November 2025) Zillow 12-month forecast: +4.0% (December 2025) Unemployment: 4.0% (November 2025) Rent index: $1,637/month (Zillow, December 2025)

Grand Rapids is the one market on this list where vacancy pressure is building from the supply side contracting, not from demand running abnormally hot. New listings are down 8.5% year over year. Active inventory has fallen 3.17%. The pipeline of available homes is shrinking.

A pending ratio of 0.992 means supply and demand are nearly in balance -- with the balance tipping toward supply shortage as the new listing decline continues. If new listings do not recover, the pending ratio will cross 1.0 and Grand Rapids will enter the same structural supply deficit as Rochester and Syracuse.

The Zillow rent index of $1,637 per month is the highest of any Midwest market on this list. That reflects Grand Rapids' economic strength: it is not a post-industrial metro transitioning from manufacturing. It is an active manufacturing and healthcare hub with a growing population base. The homeownership rate of 74.31% is the highest in this report, which means the renter pool is proportionally smaller and vacancy competition is more intense for quality units.

Home values are up 5.17% year over year and the 12-month forward forecast is +4.0% as of December 2025.

The listing price of $404,900 is the highest in this report. Investors entering Grand Rapids at this price point need to run the income model carefully. At a $342,610 Zillow home value and $1,637 rent, the gross yield is approximately 5.7%, which is tight before financing costs. The vacancy protection thesis for Grand Rapids is strongest for investors with low-cost debt or significant equity.

#5 Akron, OH: 88/100 -- Supply Score 86, New Listings Contracting

PropertyIQ Score: 88/100 (B+) Listing price: $229,500 (Realtor.com, March 2026) Zillow home value: $228,466 (January 31, 2026) New listings YoY: -0.53% Supply score: 85.6 Demand score: 92.6 Pending ratio: 0.923 Days on market: 39 Sale to list: 100.0% (November 2025) Zillow 12-month forecast: +3.1% (December 2025) Unemployment: 4.1% (November 2025)

Akron is the most affordable market on this list and provides vacancy protection through the combination of supply constraint and high demand. New listings declined 0.53% year over year as of March 2026, a modest contraction. Supply score of 85.6 indicates the market is meaningfully above average tightness. Demand score of 92.6 means buyer and renter demand is near the national ceiling.

At a listing price of $229,500 and a Zillow rent index of $1,232 per month as of December 2025, the gross rent yield at current prices is approximately 6.5% before expenses. That is the best gross yield of any market in this report.

Days on market of 39 and sale-to-list at 100.0% confirm that Akron's available supply is being absorbed consistently. A property priced correctly in Akron closes in roughly six weeks, and it clears at full asking price.

For investors whose primary concern is vacancy risk, Akron's vacancy protection comes at the lowest entry price on this list. The tradeoff is modest appreciation: the 5-year appreciation of 37.1% is respectable but below the top markets in this report.

What Low Vacancy Signals Mean for Investors

Vacancy is a lagging indicator when measured in surveys. By the time vacancy rate data shows a market tightening, rents have often already moved. The supply and demand metrics in the PropertyIQ model capture that tightening in real time, before it shows up in annual vacancy surveys.

All five markets above show the same structural pattern: demand outpacing or matching supply, with supply pipelines contracting rather than expanding. The markets where that pattern has been most persistent (Rochester, Syracuse) show the strongest appreciation. The markets where it is emerging (Grand Rapids, Akron) are at earlier stages of the cycle.

Investors who move into supply-constrained markets early capture the vacancy protection at lower prices. Investors who wait for published vacancy surveys to confirm what the supply/demand data already shows will pay more for the same asset.
