1. Gross versus net
Gross yield compares rent with purchase price. Your real result also depends on purchase taxes and fees, renovation costs, periods without a tenant, community fees, property tax, insurance, maintenance and management.
Build the numbers on total cost, and treat any projection as an estimate, not a promise.
2. The building and the unit
Two flats with the same rent can have very different risk. Building age, structural condition, installations, pending works and documentation problems change both the cost and the safety of the investment. A technical review before buying is one of the cheapest ways to protect the capital you commit.
3. Regulation
Rules on rents, on tourist rentals and on housing in general have been changing in Barcelona and in Catalonia. Check the regulations that apply to your type of use before you buy, not after, and ask a lawyer to confirm them for your case.
4. Renovation as part of the return
Many of the best opportunities need works. The renovation budget, the licences and the time the property is empty are part of the investment, so they belong in the numbers from day one.
5. Financing and taxes for non-residents
Conditions for non-residents can differ from those for residents, both in financing and in taxation. Speak to your bank, lawyer and tax adviser early, because they affect what you can afford and what you will keep.
6. Type of asset
- Flats: liquid and easy to manage, sensitive to regulation and condition
- Whole buildings: higher potential, but also works, community and legal complexity
- Industrial and commercial property: different valuation, licences and tenant logic
7. Managing from abroad
If you are not in Barcelona, who inspects, who coordinates repairs, who deals with tenants and who reports to you? The cost and reliability of that answer is part of your return.
