Port de la Mer rentals: seasonality of seaside income and how to model it month by month

Seaside property earns unevenly. An annual yield calculated as an average hides both the strong months and the ones that do not pay their way. It has to be modelled month by month.

How the year breaks down

• The cooler months are high season. Demand for short stays by the water peaks, and rates are several times higher.
• Summer is the trough. The heat limits the beach holiday, and occupancy falls along with rates.
• The shoulder season is carried by long-term lets and business demand.
• Holidays and events create separate peaks that can be seen in advance.

What follows

• A mixed model often wins: a long-term lease over the summer and short stays in season — if the building rules allow it.
• Costs are not seasonal. The service charge, cooling and maintenance run all twelve months, empty ones included.
• Furnishing only pays off with short-term letting, and its wear is uneven too.
• Plan your market entry for the start of the season, not for when the apartment happens to become free.

How to calculate before buying

• Collect rates by month for comparable apartments — not an annual average, but the monthly picture.
• Assume honest occupancy for each month, not a single figure.
• Deduct all costs over twelve months, including the empty ones.
• Compare the result with the net income from a plain long-term let of the same apartment. Sometimes there is a difference; sometimes management and wear eat it.

What else to check

• Whether short-term letting is allowed in the building — in writing, before the deal.
• Service charge and community charge, with their history.
• Guest rules and parking.
