Whatever an agent tell you, reduce instantly by 90 per cent and you may be near the mark. Otherwise, a lot depends on where you are and what you are trying to rent.
Costa del Sol – 2-bed apartment – forget it!
Nice villa with pool – perhaps 8-10 weeks in the summer if lucky.
Costa Blanca – similar, but less rental income.
Costa Brava – virtually impossible to rent outside July and August. Excellent rental from villas in northern Catalunya – up to 1,000 per week for four-beds in good condition.
Apartments in Lloret etc – forget it!
