No, and this catches buyers out every year. A mortgage valuation is for the lender's benefit — it confirms the property is adequate security for the loan. It is not a survey of the condition and it carries no duty to tell you about defects.
The inspection is 1–2 hours for a Level 2 and 3–4 hours or more for a Level 3. Most surveyors return the written report within 3–5 working days of the visit.
Yes — that is one of its main practical uses. A costed schedule of repairs gives you an evidenced basis to go back to the seller rather than an opinion.
