Its worth a try ..... but depends on the location.....are you in a prominent position where you can be seen if you put up a For Sale sign.
There are also on-line companies but most of them want a fee.
Probably worth an ad in your local paper ....it won't cost a fortune and you may be lucky.
Personally I think Estate Agent fees are extortionate for what they actually do, but they do have a database of potential purchaser which in some locations it vital.
Your solicitor does all the important work. I don't think you need an Energy Report any longer but I could be wrong.
