Havnt read the whole thread so forgive me if someones metioned this already.
Advertising a price without seeing the property is a very risky business if you ask me, especially when the price your quoting is on the low side. Presumably, the propertys in your area vary in design,What about access issues, extensions, different size windows,windows above flat roofs, People arnt going to be too chuffed if you quote one price than start increasing it to allow for these things. Cant help thinking you'll come unstuck in the long run.Nothing worse than doing a house where you know you've made a mistake with the price, you end up resenting doing it.
