Marika,
Welcome to the forum - enjoy reading the posts.
I would be very careful who you let know that you are looking to buy a property - especially when you are out in Turkey actually looking. You will find that everyone (and I mean EVERYONE)has a "friend" or "brother" who has a house for sale or is an estate agent.
That may seem like a negative statement but don't let it put you off - there are some really excellent agents in Calis and Fethiye and if you do your homework you will find life much easier.
Forums like this are a godsend to prospective purchasers - I wish this one had been here before we bought. It would have saved me a lot of "legwork" trying to find a reputable agent.
One of the best things you can do before you go over to look is to ask if anyone has had any dealings with the agents you eventually choose. You will invariably get the answers you require to put your mind at rest.
As for renting - yes lots of us do rent out our properties but one thing seems to stand out and that is - do not expect to make mega bucks and certainly do not expect it to cover the cost of borrowing lots of money if you need to do that in order to buy the house. It's not as long a season as you might think - May to Oct is about the norm for rentals - so only 6 months in reality.
Just ask if you need any more info or send me an email if you want any info on how we go about renting our place and what the on going costs are.
