We are sorry, but Dolls' Houses Past & Present cannot offer valuations. We are a group of enthusiasts and collectors scattered all over the world, and whilst each of us has a good idea what we would be willing to pay, or have paid, for a house we wanted to own, we don't have sufficient expertise to suggest a sale price for your house, especially as it could not be directly examined. It is impossible to assess value accurately from photographs.
What we suggest is that you look at what similar models have sold for recently on eBay or in salerooms (try looking at prices realised at the saleroom.com). Many of us buy on eBay ourselves: it does give a fair indication of the state of the market at any one time.
If you are unsure as to the make and model of your house, we do have a high level of expertise in identifying vintage dolls' houses, and can often date them fairly accurately as well. This we can do, and it will help you to find comparable models sold online. To do this, we shall need good, clear photographs of the house, inside and out, showing every aspect and every room, plus details of any special features, wall or floor papers, evidence of electrics, fireplaces, and makers' labels, even if these are damaged and/or fragmentary.
