Absolutely. Not everyone is, but many guests have their own projects at home, or want to do things to their homes without knowing how ot what. My renovations are quite unusual in my approach to recycled materials etc, and sometimes guests tell me they have taken ideas with them home. They often ask lots of questions too. Am nearly finished, only have one area still to go, and then I don't know how I will spend my time and money!
My price has been sliding up as the house has been getting better, started much much lower. It has been a great way to combine working on the house with renting it out at the same time in order to finance it.
Guests don't walk into a building site, it all looks quite normal until they check out and then hectic activity takes place until new guests arrive!
