If you intend to buy a home that has been lived in before, try to get as much information from the previous owners as possible about the house and the land. Have they had any problems with wildlife before? Have you made any major structural additions improvements that I have to know about? Are the plants in the garden Native to the area of brought in from other places? Have there been any cases of flooding in the said area? How about drainage, is it sufficient?
There are many more questions and there are more sources of information/answers to these questions. The many sources for such information are; the local homeowner’s association, the local government, local surveyor’s office and most important of all the real estates agents who have dealt with property in the same area. Don’t be shy or afraid to bee too inquisitive about a property for once you sign, it’s yours and yours alone (along with the unknowns you were afraid to ask about).
