Romania's Black Sea coast operates as two distinct markets: Constanța city (Romania's fourth-largest city with 300,000+ residents and a year-round economy) and the resort strip (Mamaia, Eforie, Neptun, Mangalia) which is heavily seasonal.
Understanding this duality is essential for any coastal investment.
As Romania's main port city and the largest on the western Black Sea coast, Constanța has economic fundamentals beyond tourism:
Average prices in Constanța city range from €1,200-1,700/sqm, with better-located properties near the waterfront commanding premiums. Rental yields for year-round lets run at 6-7% gross.
The coastal resorts are where the market gets interesting — and risky.
Mamaia is the premium resort, a narrow strip of land between Lake Siutghiol and the Black Sea. Prices here range from €2,000-3,500/sqm for seafront properties, with summer short-term rental income during June-September that can cover 40-60% of the annual mortgage payment.
Eforie Nord/Sud, Neptun, and Jupiter offer more affordable options at €1,000-1,800/sqm, with corresponding lower rental premiums.
Here's the critical insight: advertised yields on coastal properties are often misleading because they annualise 3-4 months of peak season income.
A realistic breakdown for a Mamaia apartment (€150,000 purchase price):
Total annual income: €17,800-26,400 → Gross yield: 11.9-17.6%
But after management fees (20-30%), maintenance, utilities, and vacancy, the net yield drops to 6-9% — still attractive, but far from the headline numbers.
Several developments could transform the coastal market:
Coastal real estate in Romania offers genuine yield opportunity, but success requires honest seasonal math and a clear strategy for the off-season months.
