I will be renting out my common room and utilities room to my friend n her family (she n her hubby + 2 teenagers + a toddler) in July. $1,400 for two rooms, include utlities bills and fully furnished. Is this amount reasonable? They will be renting for 4 years till their BTO is ready in 2017. So during these 4 years, how often and how much can I ask for increasement? (this is my first time renting out) This is a 3room flat (40 years old flat) and is at prime area - Bukit Merah View. 1 bus stop away from Tiong Bahru Plaza/MRT or 7 mins walk only from my house. 8 mins to Redhill bus interchange. I will be doing the reno for my whole house soon, so they will be staying in a brand new furnishing.
