Hi friends and experts Im interested in buying an investment property in Ipswich city council area, under the Current Title Search it has the below statement. "For depth restriction refer to plan SP 17xxxx" Im not so sure about the above statement. Some say its normal for that area. Some say its a new thing since the "Ipswich sinkhole" news. I was wondering if any can assist what it refers to and if I should stay away from this property.
