Slim, as an investment it doesn't stack up. Let's say you get the 875 for say 12 weeks, that's 10,500 before costs such as service charge, cleaning & changeover expensers, wear & tear. Your return will be less than 4%, and that is assuming you get that many weeks; there are an awful lot of apartments on the market.
If you are looking at a place to use yourself, out of season, or between bookings then that's a different matter. However, I recommend you look at the eastern Algarve, close to the Spanish border, and look at non-estate villas with pools. My partner has just such a property. We've had 18 weeks lettings this season.(In August we get £1,000 a week). It's 10 minutes from fantastic beaches and appeals to the family market - one Portuguese family from Lisbon have been three times this year and have already booked for next year. It's a very traditional area - lots of good restaurants, no karaoke bars or discos, but it is beginning to take off; lots of EU money being spent on infrastructure.
Forget the golf market. Most holiday golfers (I'm one of them) are groups of men and don't want the hassle of self-catering; they stay in hotels. Also, they don't want to play just one course. Our villa is within 15 minutes drive of 6 quality courses.
For not much more than your proposed apartment you can get a unique property with far more long term potential. It's a buyer's market and there ae lots of desperate sellers. I suggest you visit estate agents in Tavira (charming old town).
Incidentally, we'll be going over next week £20 return to Faro on RyanAir !.
