I have had a million in a fixed acc.with LH. bank for over 6-7yrs.its never been touched,but immigration sometimes ask what are you living on.i show them a different acc.that I use for living exs.i had just done a transfer uk.to Thailand for this yrs.exs.so to ease the loss on the rate [TT] I thought why not put half of it in a fixed acc.for 6months and earn about 4,000bht.me and mrs.HH have about 7accs.with LH.BANK so by them giving me some aggravation I am not a happy chappy.
too go and get a letter confirming my address,it means taxi there and back,plus imm.last time 6yrs.ago charged me 500bht.i wasn't prepared to do that.
as for the rate of return fixed for 3yrs.was 2%.but there are some banks CIMB offering decent rates.[promotions] but you need to go into one of the malls that have a lot of banks,then you will have to put up with illiterate staff.
good luck. HH.
