Turk Telecom will get the line to the property curtalige (if it is not there already) but from that point through to the inside you will need to employ an electrician to connect or cable to the point that Turk Telecom comes into the building. Cost for this work is not to bad, but expect to pay 30-100TL depending on whether there is any, and how much, cabling is required.
Cost us nothing for Turk Telecom to connect to us last year (cables were already into the site but not connected to our villa) and then the rental is about 20TL a month for a line. Broadband will cost you somewhere between 30 and 55TL depending on your usage and the deals on offer.
To order a line you need residency, passport, tax number (I think) plus your proper address. I think that about covers it. By the way if you have good turkish you'll have no problem at Turk Telecom office, but it is worthwhile taking some one with you who has, as the people there generally do not have any english, or in some cases couldn't give a monkey and are most unhelpful, even if they have!! Worst place I have come across in Turkey for giving people any assistance
