When you're buying your home, you'll need the help of several different professionals.
Here are some of the valuations and reports you can get to help you decide. Check out what some of these will cost in What it costs to buy.
Getting a valuation report done by a registered valuer will give you a good feel for the 'market value' of the home, as well as some useful information about the property. Your lender will probably want you to get one completed and could recommend someone.

You can apply for a LIM (Land Information Memorandum) from your local authority – you'll need to provide a copy of the title of the property. The LIM report will give you information the council knows about the property – flooding, consents, drainage, etc. You should also ask your local or regional authority for information about the area and any future plans eg. zoning, building heights, road development, etc.
Getting a building consultant's report is always a good idea. It will tell you if there are any potential problems or defects, and how much maintenance work you might have to budget for.
Your bank or lawyer may have someone they can suggest, or contact the Building Research Association for information.
You may want to check any structural or land issues (for instance, with a steep or unstable section). Choose a registered engineer, or one belonging to the Institute of Professional Engineers
