Depends where your property is I guess. We were in Brixton and were lucky to link up with people interested enough to lead to a private sale.
First of all get a few EAs in to give you a valuation, get at least 3 if you can. Then go with an internet company like
www.thelittlehousecompany.co.uk (there are a few of them - do a search) who for something like £75 will advertise your property on line. This is most useful not for the presence on their own site necessarily but because it'll be included in some of the big sites such as
www.findaproperty.com etc exactly the same as any Estate Agent's property advert. Please check these details as I'm going from memory. You'll need to write your own blurb and take your own photos.
In addition to advertising in Loot, your local paper, you can also make up your own sign to stick outside your place as well as generally putting the word around everyone & everywhere you know.
The process of selling privately was a complete doddle. I asked around and was recommended a good value conveyancer by a U75er - very efficient though based in Essex, however, as everything was done over the phone and by post, location wasn't an issue. Pm if you'd like his details. £350 basic fee plus VAT and standard costs for Telegraphic Transfer etc. Everyone else I'd been recommended was charging upward of £600 basic.
Edited to say: An EA doesn't haggle for you to get the 'best price', they usually just let someone in to have a look around then close up after them. Maybe call the next day, find out if they were interested. The real work is done by the conveyancer. As for going through an EAs mortgage advisor to sort out a mortgage.. I went that route with the place I've got an offer on, I didn't do it before and I wouldn't bother doing it that way again. I ended up finding myself a mortgage that suited me better and it's easy enough to fill in the mortgage forms. An EAs mortgage person adds nothing of real value to the experience.
