Frequently Asked Questions About Rental Investment
What is a good rental yield in Spain? ▼
A gross rental yield of 5-7% is considered good in Spain. Net yield (after expenses, taxes, and vacancies) is typically 3-5%. In major cities like Madrid or Barcelona, yields tend to be lower but with greater security, while medium-sized cities may offer higher returns.
What is cash flow in a real estate investment? ▼
Cash flow is the difference between rental income and all associated expenses (mortgage, taxes, insurance, maintenance, management). A positive cash flow means the rent covers all expenses and generates monthly profit.
What expenses should I consider when buying to rent? ▼
Consider: mortgage payments, IBI and other local taxes, home insurance, maintenance and repairs (estimated at 1-2% of value annually), property management if delegated, vacancy periods without tenants, and income tax on rental earnings.
How long does it take to recover a rental property investment? ▼
Recovery time depends on the purchase price, down payment, and net yield. In Spain, with an average 4-5% net yield, recovering the down payment can take 8 to 15 years. Our calculator shows you the exact break-even based on your data.
