Hi Cupert,
When we moved to Malaysia we were staying at Tanjung Bungah for about 1 1/2 year. Short time after we arrived, we were looking around for a place to buy, but I didn't like staying in a Condo (never know who will stay on top of you) but prefer landed property. On the other side I like it having pool area etc in the premise.
So we tried to find a gated community with full facilities, but couldn't find it on the island. Some more, after a while got a bit troubled to check the hour of the day whenever you were planning to go downtown (you don't want to get stucked in a school area when they are finishing class, believe me!).
Than we got introduced to an ongoing project in Butterworth, what they called a "landed condo" and that's what it is...
We are now living here around 1/2 year and we love the place!
I only can confirm all the "Pros" my friend Stuurman did mention before...
We are about 3-5 minutes from the ferry and very closed to everything for your daily needs (and more)....
Walking distance for food, minute drives to super markets (Giant, Jusco, Tesco extra) and shopping mall (Sunway)
And a trip to the airport takes me 30 to max 45 minutes - from Tanjung Bungah it can take you 60 minutes upto 1 1/2 hour, depending on the time of day...
Frankly speaking, the only
con for me is, that it takes me a little while longer to meet up with my friends who are staying on the island.... (but as long as the AC in the car works its not a big deal) - but if you are lucky and the ferry is just waiting for you, than it takes me a click only to visit them...

There is always a hot coffee, cool tiger or one of my "famous" frozen daiquiris available...

But be aware... my wife's cousin from Australia had a look - bought the house to my left side right away
my brother in law stayed with us for a long weekend - bought the house to my right side

Unfortunately there is no buying from the developer anymore and the price on the second market is above 500K now... but that's still less than half what it would cost you on the island...
Ok - guess that's enough promotion

There are some more places around here as well as a new one coming up from the same developer.. check it out.... the mainland is no longer the kampong as it was years ago...
Ciao
