Rent a room or a house in Tiruvannamalai. Don't pay more than 3000 rupies the month.
The last years Tiruvannamalai is growing. The local people are building continuously houses and rooms for rent. In 2006 you could rent a house with 2000 rupies and in 2009 they were asking 6000 to 8000 rupies!
The foreigners, that dont know the situation are being exploited, from the local Tamil people! Actually now in 2010, there are so many rooms to rent, that you can put the prize down to 3000 rupies.
In Tiruvannamalai the high season is only 3 months, January to March. So if you come earlier or later, almost 200 rooms are empty. And even in the high season, dont pay more than 4000 rupies.
Just rent a room for 2 days, so you will have the time to go around and search.
The Tamil people are very stuborn and stuck. So just tell them: if you want your room to be empty, and make no money, you can continoue asking 6000 to 8000 the month. Me i dont give you more than 3000. And there are so many empty rooms!
In Tiruvannamalai, the local people work all the month for 1000 to 3000 rupies. So 3000 rupies are equal to 1000 euro payment in Europe.
So 3000 rupies are very good money for them!
