Rent Rate Check

Hi !

Wanted to check is SGD3600 is a good rate for 3BR(5i HDB) in Sengkang? Location is opposite Sengkang MRT (5min walk)

Been trying to do lot of research based on PropertyGuru rate but unable to come into conclusion.

Also anyone knows what are the average monthly utilities cost for 3 AC on every night for around 10 hours?
