Your own month versus rental income: how to choose it and calculate break-even

In brief (October 2026). In our illustrative model a 150,000 euro resort one-bedroom earns about 13,700 euro a year and nets about 5,200 euro, a 3.4 percent yield before tax and financing. Taking one owner month in July or August cuts that to 2.2 percent; in April, May or October to 3.1 percent; in the winter months to 3.3 percent. Each owner night costs about 61 euro in peak season, 18 euro in the shoulder season and 5 euro in winter. The model stays above zero down to about 18 percent occupancy, but a ten-point fall in occupancy removes almost a third of the net income.

What this article calculates

You are thinking of buying a flat in a resort you know, letting it to guests and keeping one month for yourself. The question is what that one month costs, which month to choose and whether the rest of the year still earns enough. Everything here is a model built from stated assumptions. It is not market data. Use it as a template: replace the numbers with those of the flat you are looking at. The overview of the idea is in the main guide.

The assumptions

The resort is a northern-Mediterranean type with four seasons. Nights per year add up to 365.

• Peak: July and August, 62 nights.
• High: June and September, 60 nights.
• Shoulder: April, May and October, 92 nights.
• Low: November to March, 151 nights.

Three example properties:

• A one-bedroom for 150,000 euro. Nightly rate by season: 120, 85, 62 and 40 euro. Occupancy: 80, 68, 48 and 25 percent. Cleaning 30 euro per stay, average stay 5 nights. Utilities 1,440 euro a year.
• A two-bedroom for 300,000 euro. Rates 220, 155, 110 and 70 euro. Occupancy 82, 70, 50 and 27 percent. Cleaning 45 euro per stay, average stay 6 nights. Utilities 2,000 euro a year.
• A villa for 600,000 euro. Rates 480, 330, 230 and 140 euro. Occupancy 70, 58, 38 and 18 percent. Cleaning 90 euro per stay, average stay 7 nights. Utilities 4,200 euro a year, including the pool and garden.

Costs common to all three:

• Management 20 percent of revenue. Our short-term versus long-term guide gives 15-25 percent as the usual range; see property management companies abroad for what the contract should say.
• Platform and payment fees 5 percent of revenue, a blended assumption.
• Maintenance and replacement reserve 6 percent of revenue.
• Fixed yearly costs (community fees, local property tax, building insurance) 1.2 percent of the price, 1.4 percent for the villa.

The result is net operating income: before income tax, before any mortgage and before purchase costs. Add buying costs to the price when you judge the yield; our Spain guide, for example, puts them at 9-13 percent.

The base case: letting twelve months

The one-bedroom earns 13,668 euro, of which the 62 peak nights bring 5,952 euro (43.5 percent), the high season 3,468 (25.4), the shoulder season 2,738 (20.0) and the 151 low-season nights 1,510 (11.0). It is occupied 172 nights, 47 percent of the year, over about 34 stays.

Its costs total 8,511 euro: management 2,734, platform fees 683, cleaning 1,034, utilities 1,440, fixed costs 1,800 and the maintenance reserve 820. Net income is 5,157 euro, a net yield of 3.44 percent on the price.

• Two-bedroom: revenue 25,609 euro, costs 14,886, net 10,723 euro, yield 3.57 percent, occupancy 49 percent.
• Villa: revenue 44,162 euro, costs 28,095, net 16,067 euro, yield 2.68 percent, occupancy 38 percent.

These are in line with the 2-4 percent net range our country guides give for many resort markets; see rental yield by country. The villa is lower because large units fill less often and carry heavier fixed and running costs.

What one owner month costs

Now remove 30 nights from one season. You stop earning on those nights and you stop paying the variable costs on them (management, platform fee, cleaning, maintenance share), but you still pay the fixed costs and the utilities. The loss is therefore smaller than the revenue you give up.

One-bedroom, 150,000 euro, loss of net income and the resulting net yield:

• Owner month in peak season (July or August): 1,843 euro, which is 61 euro a night; yield falls to 2.21 percent.
• High season (June or September): 1,074 euro, 36 euro a night; yield 2.72 percent.
• Shoulder season (April, May, October): 530 euro, 18 euro a night; yield 3.08 percent.
• Low season (November to March): 162 euro, 5 euro a night; yield 3.33 percent.

Two-bedroom, 300,000 euro:

• Peak: 3,550 euro, 118 euro a night; yield 2.39 percent.
• High: 2,088 euro, 70 euro a night; yield 2.88 percent.
• Shoulder: 1,026 euro, 34 euro a night; yield 3.23 percent.
• Low: 330 euro, 11 euro a night; yield 3.46 percent.

Villa, 600,000 euro:

• Peak: 6,685 euro, 223 euro a night; yield 1.56 percent.
• High: 3,738 euro, 125 euro a night; yield 2.05 percent.
• Shoulder: 1,663 euro, 55 euro a night; yield 2.40 percent.
• Low: 452 euro, 15 euro a night; yield 2.60 percent.

Compare it with what a guest pays

The loss to you is not the price a guest would pay for the same 30 nights. At the model's own nightly rates, a guest staying 30 nights in the one-bedroom would pay 3,600 euro in peak season, 2,550 in high season, 1,860 in the shoulder season and 1,200 in winter. Your cost is 1,843, 1,074, 530 and 162 euro. That is about half of the guest price in peak season, 28 percent in the shoulder season and 14 percent in winter. This is why owning can beat renting for the same trip, but only if you actually take the shoulder or low months; in August the saving shrinks.

How to choose the month

• Peak is the most expensive owner month in every example. If you must use it, accept the 2.2 percent yield or consider a second, cheaper visit instead.
• The shoulder season is the best compromise: the weather is usually good and each night costs about a quarter to a third of a peak night.
• The low season is almost free in lost income but may be cold, rainy or closed down. Visit it before buying.
• Do not take the month as a single block unless you must. A manager can usually fit two or three weeks in the shoulder season; see managing the home and blocking dates.
• Outside the Mediterranean the seasons move. In Thailand and Dubai the quiet months are the hot summer; see the Thailand and Dubai articles.

Break-even occupancy

Break-even here means the occupancy at which the flat just covers its own running costs, with net operating income of zero. To find it we scale the occupancy of every season by the same factor and look for the point where income equals costs. For the one-bedroom the factor is 0.386, which means about 18 percent occupancy across the year. For the two-bedroom the factor is 0.343 (17 percent) and for the villa 0.44 (17 percent).

Do not read this as a comfortable margin. Break-even says only that the flat pays its fixed costs. The return is made on top of it. A 3.4 percent net yield needs 47 percent occupancy in the model. Bookings that sit at break-even earn nothing for the capital, and a tax charge or a repair can push them under.

What a fall in occupancy or rates does

Twelve months of letting, one-bedroom:

• Base case: net 5,157 euro, 3.44 percent.
• Occupancy 10 percentage points lower in every season: net 3,700 euro, 2.47 percent.
• Nightly rates 10 percent lower: net 4,214 euro, 2.81 percent.

Eleven months of letting, owner month in the shoulder season, one-bedroom:

• Base: net 4,627 euro, 3.08 percent.
• Occupancy 10 points lower: net 3,281 euro, 2.19 percent.
• Rates 10 percent lower: net 3,746 euro, 2.50 percent.

Two-bedroom, twelve months: 10,723 euro (3.57 percent); occupancy minus 10 points 7,986 euro (2.66); rates minus 10 percent 8,956 euro (2.99). With the owner month in the shoulder season: 9,697 euro (3.23), then 7,165 euro (2.39) and 8,044 euro (2.68).

Villa, twelve months: 16,067 euro (2.68 percent); occupancy minus 10 points 10,198 euro (1.70); rates minus 10 percent 13,020 euro (2.17). With the owner month in the shoulder season: 14,405 euro (2.40), then 8,973 euro (1.50) and 11,539 euro (1.92).

A ten-point fall in occupancy costs the one-bedroom about 1,460 euro a year, more than its entire shoulder-season owner month. In other words, the largest risk is not your own month but a weaker year than the seller promised.

Traps

• Using the seller's occupancy and rates. Ask for booking history from a platform statement and cut it by ten points and ten percent as a test.
• Counting the owner month as free. It costs between a few euro and over 200 euro a night here, depending on season and size.
• Taking the month in July or August because you always went then.
• Forgetting that taxes can change the picture. Personal-use days can change deductions; see personal-use days and rental income taxes.
• Ignoring licences. Letting fewer nights can put the property into a different category; see licences, condo rules and insurance.
• Forgetting financing. With a mortgage at today's rates the net yield above would be eaten by interest.
• Judging by yield alone. A flat with a lower net yield may still suit you better if the owner month is cheap and the location is liquid when you sell.

How to build your own model in an hour

1. Take the price and add your buying costs; that is your capital base. 2. List the four seasons for the resort and the number of nights in each. 3. For each season find a nightly rate and an occupancy from real booking data for comparable flats, not a brochure. 4. Multiply to get revenue. 5. Subtract management, platform fees, cleaning, utilities, fixed yearly costs and a maintenance reserve. 6. Remove 30 nights from the season you would choose and repeat. 7. Run the two shocks: occupancy minus ten points and rates minus ten percent. 8. Compare the result with the yields in rental yield by country and with a deposit; see rental yield versus deposit interest.

FAQ

What is a good net yield for this model? There is no fixed answer; our country guides show roughly 2-4 percent net in many resort markets, and this model gives 2.7-3.6 percent before tax and financing. Is the owner month ever free? Close to it in the low season, about 5 euro a night in our one-bedroom, but that is the season you may not want. Is one month the right amount? It is the base case; every extra month in the shoulder season costs another 500-1,700 euro depending on the size of the property. How do I find occupancy for a particular flat? Ask the seller or the manager for statements from the booking platforms for the last 24 months and compare with similar flats in the same building. Does a mortgage change the decision? Yes, strongly; interest is not in these figures and at current rates it can exceed the whole net yield.
