I used the local agents, went in the 3 main ones in the midlevels area. After 5 minutes in each office I realised that they all had exactly the same properties for rent so went back to the first one.
After the first day the local agent knew my requirements and did not waste my time, they are used to dealing with expats. See as many as you can in the first day, and make clear what you do and dont like.
Ended up putting an offer in on two properties. The first one, was taken off the rental market and put up for sale instead, the second one refused my offer which was 7k under the asking price, I increases my offer by 2K and they still refused. I walked away, and started looking at new flats, and 5 days later the second flat accepted my offer 5K under the asking price.
I also know the landlady had an offer of the asking price for two single australian guys on the same property, but she refused and took our offer as we were a couple!
So once you have found the property you like, you still might not get it!
Also check out the buildings first, on
www.hongkonghomes.com you can look at all the buildings within a certain area, look at floor plans and pictures. The apartment we ended up in was in one of the buildings I liked from the website.
Also make sure you have the deposit/first months rent in a HK bank account with a cheque book, you cannot use a visa debit card and a bank transfer from UK can take around 5 working days.
