Location, seasonality, costs, regulations, architecture: the method for assessing the profitability of modular accommodation yourself.
No modular accommodation, whether a tiny house, a home or a unit designed for outdoor hospitality, is profitable by nature. Its rental performance depends on a set of criteria that are better learnt and assessed yourself before buying than discovered afterwards. Investing is one of the main types of AIIA project, alongside living, hosting and working, presented in our reference article on what a turnkey modular home covers. We have already detailed a first application of this method for the specific case of a tiny house intended for seasonal tourist rental in our article investing in rental accommodation: what follows generalises its principles to any investment project in modular accommodation, whatever the model or operating mode envisaged.
Understanding the subject
The first criterion is location, and more precisely how well it suits the planned operating mode. A property intended for short-term tourist rental must be in an area where real demand exists at certain times of the year. A property intended for long-term rental depends more on proximity to employment areas or transport links. A project with a professional purpose (hosting groups, staff housing, business extension) follows a different siting logic, tied to the company's site or the operating land rather than to a tourist area. The same location can therefore be excellent for one use and unsuitable for another: the question is never “is this location good?” but “is it good for the use I am planning?”.
The second criterion is the seasonality of demand. Accommodation in a very touristy area in summer can show an excellent occupancy rate for a few months and remain largely empty the rest of the year; a home intended for long-term rental follows a more stable demand pattern, but is subject to other uncertainties (tenant turnover, vacancy between two leases). In both cases, good practice is the same: reason on a realistic annual average rather than on the best period, and never extrapolate an occupancy rate observed over one month to the whole year.
Going further
The third criterion, often underestimated, is the recurring operating cost. It varies with the operating mode: cleaning, booking management, specific insurance and tourist tax for tourist accommodation; routine maintenance, rental management and vacancy between two tenants for long-term rental; maintenance and business-specific costs for professional use. Whatever the case, these costs must be deducted from gross income before judging a project's real profitability: an attractive purchase price says nothing, on its own, about what will be left once these running costs are paid.
The fourth criterion is local regulation, which varies greatly from one municipality to another and according to the intended use. Some areas strictly regulate short-term seasonal rental, require registration or limit the number of nights allowed per year for a second home; other rules apply to long-term rental or to certain professional uses, such as staff housing. We do not provide legal advice on this point: before committing to a project, it is essential to check with your town hall or a legal professional the precise rules applicable to your land and to the use you have in mind.
The fifth criterion, often neglected in favour of financial calculations, is the architectural appeal of the dwelling itself. Accommodation with distinctive architecture and visible build quality generally rents more easily, and at a higher rate, than standardised accommodation: it is a qualitative factor that weighs as much as location in a tenant's or traveller's decision. This is precisely the positioning of models designed for rental operation, such as Frame within the Resort Collection, or Level, whose panoramic terrace is a rental asset in its own right.
Practical advice
These five criteria, location, seasonality, operating costs, local regulation and architectural appeal, do not replace a personalised study specific to each plot and each project. They do, however, allow you to build your own assessment grid before any purchase, rather than relying on an advertised yield without checking it. We do not publish occupancy rates or yield figures specific to our dwellings: these data depend on too many factors specific to each plot, each local market and each operating mode to be reliably generalised, and we prefer to invite you to build them yourself, criterion by criterion, rather than offer you a figure that would not apply to your project.
For a concrete application of this method to a specific case, that of a tiny house intended for seasonal tourist rental, our article investing in rental accommodation details each of these five criteria in that particular context. If you would like to estimate an initial order of magnitude for your own project, our Invest section offers an indicative yield simulator, to be refined afterwards with your own study. You can also configure your project directly from our configurator.
