Not Just a Trend: The Demographic Reality
Official figures confirm that single-person households are drawing attention: as of January 1, 2024, they already represented nearly 28% of households in Spain (around 5.4 million people living alone). According to the INE Household Projection (2024–2039), if current demographic trends continue, single-person households could reach 7.7 million by 2039, 33.5% of the total—an increase of 41.9% compared to 2024.
This trend, which reflects population aging, a reduction in family unit members, and changes in lifestyle habits, has direct implications for housing demand and accessibility, market composition, and urban planning.
Why Living Alone Can Be a Significant Challenge
Increased Fixed Costs
In a single-person household, all fixed expenses (rent or mortgage payment, utilities, insurance, IBI, community fees, maintenance) fall on a single income. In strained markets like Barcelona or Madrid, this burden makes many homes inaccessible without sharing.
Fewer Economies of Scale
Sharing a home allows for the distribution of utility, insurance, and household expenses; living alone eliminates these economies and increases vulnerability to unforeseen economic events (unexpected repairs, sick leave, etc.).
More Demanding Credit Access
Financial institutions assess repayment capacity. For a single person, a higher initial saving, more stable salaries, and often family guarantees are usually necessary to access favorable mortgage conditions.
Lack of Savings and Fragility in the Face of Changes
A single salary has less tolerance margin for income loss or increased payments, which can lead to insecurity if there isn’t an adequate emergency fund.
Practical Alternatives and Solutions
There are alternatives that reduce the economic and operational burden for those who wish to live alone without exposing themselves to excessive risks:
Shared Spaces or Regulated Co-living
Co-housing or co-living modalities offer independence with lower costs and shared services.
Shared Purchase or Cooperatives
Co-ownership models or cooperatives reduce the initial effort and allow access to housing with less financial impact.
Smaller Homes or Peri-urban Locations
Opting for smaller properties or areas with a better quality/price ratio can be a viable solution.
Adapted Financial Products and Insurance
Mortgages with grace periods, insurance covering income loss, and programmed savings instruments can increase security.
Planning and Emergency Fund
As a rule, having a contingency fund and budgetary planning is essential to sustain residential independence.
What Can Administrations and the Private Sector Do?
The viability of this option for more people requires coordinated measures:
- Incentives for affordable housing supply and micro-housing promotions.
- Fiscal and financial products aimed at individual buyers.
- Inclusion programs for elderly people living alone.
- Development of private services and products that minimize risks.
At Llach Serra, We Help You Manage It
The growing presence of single-person households reflects profound social changes. However, living alone implies additional costs, financial risks, and a need for planning that many do not consider beforehand. Making this option possible for a wider number of people requires individual measures (planning and advice), adapted products and services, and public policies aimed at housing accessibility and security.
If you are considering living alone, the recommendation is to conduct an honestly detailed financial analysis and consider alternatives and support. At Llach Serra, we offer advice to assess the viability of your decision: a comparison between renting and buying, a financing study, and options adapted to each profile.
