Hi, I am feeling silly to ask this question. Many times, insurance companies often asked me which year the house was build in. I was always not sure which year my properties were built. I was told that the council might be able to help. But I'd just like to know which tools or techniques other investors used to know the year a property was built. Especially, we have been buying established properties, meaning that there have been many owners even before us. Cheers!
