gundar: I've considered this before - selling my place myself. What I did to start was pop into Whitcoulls and pick up one of those self-help books - How to Sell Your Own Place - or similar title. After I read through the legal, moral and technical issues, I figured I'd just give to an agent to do and ask for a price that covers their fee. As has been said, nothing prevents you from going it alone and if you don't have any problems with your house that could come back at you later, if it's as good a deal as you say, the self sale should be just fine, but then, in that perfect world, the agent will see thhe potential and get you a better deal - they also want quick profitable sales.
The thing that always comes to my mind when people complain about agent's fees is the number of startups that have tried other models of real estate agency practice and failed, some spectacularly, for example - The Joneses.
I will probably sell my current house next year and I am considering this advice I got from a friend in the industry - If you want to make a few more k$ on your sale to make it worthwhile or to cover agent's fees for example, you could include other sweeteners - try including a new lawnmower and edge trimmer in the chattels list (if it's a big garden); banks are now offering iPads, cash, appliances etc on mortgages and there's no reason your list of chattels can't also include that wall mounted flat screen TV that would be difficult to move and diffficult to install anyway. How about some new whiteware that already fits well in the laundry room? How about a years paid up security monitoring? - these things cost you relatively little and actually add value and incentive to the new buyer if you get the market right. If you are going to target first home buyers, a new lawnmower would be awesome. If you live in a neighbourhood that has a bad reputation, a free security service would be sweet.
Good luck with your sale, it does seem to be a buyers market in Hamilton at present, some sales in my immediate area seem to have been really quick ('for sale' became 'sold' in a month or two, although I don't know the financial details).
All that does is inflate the price each time the house sells, as the hose has to sell at 5% more each time to cover the agents fee. This is possibly one reason that has caused house prices in some areas to increase more than they should, and increases property inflation. Overseas the commission agents get is quite a bit lower say 2%, and in small NZ towns commissions can be 3%. I have found you don'tusually get any more for chattels, as people will still want to get a property for around the RV. The RV though doesn't include chattels or improvements that don't need a consent, such as exterior landscaping and decking.
I have used 200 square which is a fixed fee of less than 5k, and it was very successful. Within a few weeks it was sold for what I wanted, and it had previously been on the market privately for several months. It is good because you only pay for the services you want, so it is a DIY system, but the agent handles all the negotiation and sales.
