In Singapore, you can still choose and pick. Get those better expatriate tenants. I'll never allow Chinks nor Indians as my tenants. I'd rather wait. 1 of my neighbors and also 1 of my brother's neighbors, had rented out their units to Chinks, who subsequently partitioned their units and sub-leased to more Chinks. Believe it or not, even the bomb shelter is not forsaken but also being sub-leased!!! Eventually, they were evicted with their deposits forfeited.
In Johor, there are not many expatriate tenants although I do see more ang mohs in the Bukit Indah vicinity lately, definitely from those universities and hospitals. I'd once spoke to a Briton in TESCO Bukit Indah who is here for a 2-year contract with a university in Edu-City. Otherwise, if you get Malaysian tenants, most are non complying and some have even absconded, like my 2 neighbors had experienced. They even had to pay for their utility (TNB and SAJ) bills eventually, in excess of their deposits. In Malaysia, the utility companies will go after the house owner for all unpaid bills, unlike in Singapore, where the PUB goes after the account holder instead.
