There are a number of different types of survey. What you will need depends on the condition & age of the property, and how much your budget is. Typically there are 3 options a mortgage valuation, a homebuyers report or a full building survey. The Mortgage valuation; Used by mortgage lenders to asses what the property is worth, note any major damage and confirm it is sufficient security for the loan. Homebuyers Report; More detailed report however still “non-intrusive” so the surveyor will not move any furniture, lift floor boards or drill holes. This means the report they produce will be limited to what they can see. Full Building Survey; Building surveys can be expensive but maybe worth the cost, particularly if looking at old or unusual properties. The surveyor will go into the attic, check behind walls, and looking between floorboards and ceilings, you will receive a thorough report including advice on repairs, potential costs and what may happen if not repaired.
