Late 40 scared? There are ppl in their 50s doing triathlon.I am not familiar with such rules of foreigners cannot buy single storey houses. Have to check. What I know is that, the rules differ from states to states. I learned from a friend from Melacca he said the laws in Melacca prohibits foreigners inheriting terrace houses from their Malaysian parents. Seemed like Perak allows foreigners to inherit leasehold terrace houses from their Malaysian parents. So, it really depends on which states one is residing...
Lift is another big elephant in the house. One landed owner in Singapore told me he paid $20,000 per year to get his lift maintained and certified to be safe... Malaysia probably has no such restrictions but the cost to maintain the lift should be exorbitant because double storey usually have two to three flights of stairs to second floor, how to make the lift turns, I have no idea. So single storey made the maintenance easy and simple. I have heard some storey that the tenant chosen to rent the single storey at same price as the bigger, more spacious double storey house because she is late 40 and scared of tripping and falling from climbing up second floor.
