$900 p/m. Easy to cut back to $500 a month for a smaller place, or $300 to lose the view too, or $200 to lose the location too. You wouldn't want to go any lower than that though.
Where are you? You can get a nice 2 bedroom in phuket for $200.
Pattaya, I guess the rental market is diverse. I didn't care for Phuket much myself - a bit of a tourist trap I thought.
