I went to look at Once pattaya on 3rd road (north pattaya end). 35sqm were 4m ...higher floors more, lower were a bit less. But its too small, i couldn't live in that size. Bigger ones about 6m.
My central pattaya rent is 22k/m for 53sqm. Will be increasing next year. These condos seem to age fast though.
I've hate paying rent, but its negligible so no big deal. Keep renting for now.
