Living in JB for retire

We went to JB last friday. My firend and I are thinking the cos tof living in Singapore is very high. Thinking to move to JB to stay. That side condo rental is very cheap 4 room flat is only RM$1200 including furniture. Compare to Singapore this type of living standard we have to pay at lease $3K for rental. We sublet our 3 room flat and move there to stay save so much money.
