I have been in Bang Bo for 2.5 months now. I have rented a lovely condo for 6 months and the complex has a free swimming pool, a free gym and a free sauna. All for 4,800 a month. Plus electricity and water. Total last month including rent was 6,250 Baht.
There is a river a 10 minute walk from my condo where fishing is free, I love fishing .
My fishing rod and tackle bought at a local store for less than €25 .
There are 5 or 6 restaurants within 10 minutes walk of my condo and I can buy a lovely Thai meal for less than £2 at all of them.
I don't drink alcohol. I don't smoke and I eat mostly in my condo on salads . Because I like salad in hot weather.
I don't do bar girls either
Last month and the month before including rent and food I spent £415 in May and £425 in June ( <€500 )
Half way through July now and I will again be spending less than €500
you can easily manage on 920 a month. Don't let people put you off from at least trying. I live a fantastic life here on £650. I am not at a beach town though.
