Why Athens’ hottest districts are delivering weaker rental returns

Athens snapshot: foreign demand hurts rental yields in unexpected ways

The Greece real estate market has surprised many investors. In the first 100 words: foreign buyers flocked to central Athens and the southern suburbs over the past decade, but those same areas now show some of the lowest rental yields in the region. Our analysis of the new “Thermometer” of the real estate market — based on Spitogatos data and presented at the "Greece 2026: Business, Real Estate, Investments" event — explains why rising sale prices outpaced rents between 2019 and 2025, lowering cash returns for buy-to-let owners.

Hook: high prices, lower cash returns

That sentence is a blunt one: higher demand translated into higher sale prices faster than rent rises. For buy-to-let investors chasing reliable rental income, this is a problem. The report gives a clear metric: how many months of rent it would take to cover the purchase price for a property delivering €1,000 per month gross rent. The results are telling and, frankly, a warning sign for anyone equating popularity with yield.

How the Thermometer works and what it measures

The Thermometer is not a survey of sentiment. It is a simple ratio built from Spitogatos market data: the platform’s average sale price and average rental price for apartments across Attica, compared year-on-year from 2019 to 2025. The question it answers is practical: “How much capital does an investor need to buy a home in each area to achieve €1,000 per month in gross rental income?”

• Data source: Spitogatos platform (sale and rental prices 2019–2025)
• Presented at: "Greece 2026: Business, Real Estate, Investments" event
• Organiser: investor and analyst Ilias Papageorgiadis
• Commentary: Spitogatos CEO Dimitris Melachrinos

The metric converts sale prices into a months-of-rent figure: purchase price divided by monthly rent. The report highlights a counterintuitive result: areas with very different demand structures can have similar yields.

Key findings: Glyfada, Petroupoli and Drapetsona in focus

The Thermometer singled out a few areas that make the point clearly. Here are the headline figures for the number of months of gross rent required to match the purchase price for a property producing €1,000/month:

• Glyfada: 342 months
• Petroupoli: 335 months
• Drapetsona: 332 months

Put another way, that implies approximate purchase prices of €342,000 in Glyfada, €335,000 in Petroupoli and €332,000 in Drapetsona to deliver the same gross rent of €1,000. The key takeaway is in the comparison: Glyfada’s purchase price is much higher, yet its months-of-rent metric is similar to much cheaper suburbs. Spitogatos CEO Dimitris Melachrinos commented: “the most typical example is the similar yields observed in areas with completely different demand. Yes, the purchase cost in Glyfada is much higher, but the yield is similar, which shows the great lack of supply of properties for sale in Petroupoli and Drapetsona, an element that has raised prices.”

This shows two drivers of yield compression:

• Sale prices rising faster than rents in high-demand areas; and
• Low listings and supply shortages pushing sale prices up in less central suburbs.

Why sale prices outpaced rents between 2019 and 2025

Understanding why values rose more than rents requires looking at both demand and supply dynamics. From the Thermometer and Spitogatos data, these factors emerge:

• Strong foreign buying interest in central Athens and the southern suburbs has lifted sale prices. International buyers often pay cash or higher down payments, which pushes prices up at the top end of the market.
• Rents rise slower because tenancy contracts, local wage growth, and tenant affordability cap how much landlords can charge in the short term.
• Supply shortages in some outer suburbs reduce the number of homes available for sale, so even with weaker rental demand the sale price can climb for the limited stock that does appear.
• Tourism-related seasonal rentals can inflate headline monthly rents in coastal suburbs but do not always translate to steady long-term yields on full-year averages.

From an investor’s perspective, that combination means capital required for a given rental return increases — while the monthly income you can expect does not grow at the same pace.

What this means for buyers and investors — our analysis

We look at this as investors, not cheerleaders. The Thermometer is a practical tool for buy-to-let decision-making, and it points to several implications:

• Cash yield compression: If sale prices grow faster than rental income, the gross rental yield falls. That reduces short-term cash returns and lengthens the payback period.
• Capital-intensive buy-to-let: To reach a target gross income of €1,000/month, an investor may now need €330,000–€340,000 in purchase price in several Attica suburbs. That is a major capital outlay for many buyers.
• Be careful with assumptions: Popularity and foreign demand do not automatically equal better yield. In some cases, high demand simply pushes prices beyond what local rental markets can absorb.
• Supply matters: Areas with limited listings can still see price rises that compress yields, even if they are not fashionable right now. This is important for value-hunting investors who assume cheap suburbs equal high yield.

From our experience, a balanced investor should look at both cash yield and capital growth potential. For some buyers the priority is capital gain; for others it is steady cash flow. The Thermometer helps decide which suburbs fit which aim.

Strategy: how to use the Thermometer when evaluating Greek property

If you are considering real estate investment in Greece, use the Thermometer as part of a checklist rather than a single decision-maker. Practical steps we recommend:

1. Calculate gross and net yields

• Gross yield: annual rent divided by purchase price. The Thermometer’s months-of-rent metric can be converted into gross yield.
• Net yield: subtract taxes, management fees, maintenance and vacancy periods.
