imp,
i think there will be the odd place open in altinkum. there are a couple of thousand brits living all year round there. also. the town of didim is a twenty minute walk away up a lovely boulevard (or take a dolmush) there are eating places there.this town is a working town and the locals do like to eat out. it is good turkish food (casseroles etc.)
i think once the marina is built and more people buy there too, the resort will stay open. usually it is the end of october when the season used to end. you may be better going into the site, absolutely altinkum and asking any questions there on the web, as a lot of them on the site live there all year round.
we bought in altinkum three years ago and we went out to see a rep who took us to various sites. during the week we were there we went looking ourselves and did buy from a builder we met who was working on his apartments. as you will see you will be spoilt for choice. from one end of atlinkum to the other is full of properties. get on the dolmush and have a good look round. where the marina is to be built there are loads of properties. also try and take the dolmush that has the name yesilkent on it. it is a five minute ride from altinkum and the scenery is second to none. there are sites there which are selling. it is a very pretty place.
our rep wasn't too pleased we did not buy from her but we did not see anything we liked. we still see her when we go for holidays, walking by and she does say hello. i suppose you have been there anyway so i do not have to describe to you the lovely beaches.
we are still happy that we bought out there and wish we could spend more time than we do out there. also, we did save six hundred pounds per couple (our close friends bought too) not paying the rep but we paid a solicitor in didim and paid for an interpreter (who was worth the money) so we felt we were in control.
we are still friends with our builder and meet with him each time we go out.
any questions feel free to ask. please think too, that if you are buying to rent the property out and make money, dont expect a great return. we do not rent our place and at the moment the season isnt as long as resorts further south. it gets colder in winter and rainy .
