Calculate AffordabilityProperty Valuation Process
Valuation Types
Desktop Valuation
Computer-generated using comparable sales data. Quick but less accurate for unique properties.
Drive-by Valuation
External inspection only. Common for remortgages and lower-risk applications.
Full Inspection
Surveyor visits property internally and externally. Most thorough and accurate method.
Specialist Valuation
Required for unusual properties: listed buildings, thatched roofs, or non-standard construction.
Valuation Outcomes
- At Purchase Price: Application proceeds normally
- Below Purchase Price (Down Valuation): May need larger deposit or renegotiate price
- Retention: Funds held back until repairs completed
- Mortgage Declined: Property deemed unsuitable for lending

- Incomplete bank statements: Missing pages or months
- Unclear income source: Irregular deposits not explained
