The Property & Underwriting Logic Check
Generic property reports tell you what the street sold for—then multiply your tax return by a High Street 4.5× multiple. We audit both sides of the deal: indexed Land Registry comparables where records exist for the postcode (a regional comparable model where they do not), surveyor down-valuation risk, and what specialist underwriters actually lend against your retained profit, day rate, or 1-year accounts.
Chapter I · Valuation & Surveyor Audit · SW11 1AA (Wandsworth, London)
Fair Value Range & Surveyor Down-Valuation Exposure
No HM Land Registry transaction records were matched for this postcode, so these comparables come from a regional comparable model. They are modelled estimates, not recorded sales. Outliers trimmed via IQR filter. Historical sold prices are indexed forward at an assumed 3.2% a year — our own assumption, not the published UK House Price Index.

Surveyor Down-Valuation Risk
moderate Risk£28,000 Shortfall

Chapter II · Why Generic Property Portals Get Your Affordability Wrong
High Street Bank vs. Specialist Underwriting (Over 65 Lenders)
Standard property portals multiply a single household income figure by 4.5×. Select your income structure below to see how a High Street desk treats your application for SW11 1AA versus specialist underwriting.
Your Income Figures
Specialist underwriters assess your share of total retained profit—not just drawn dividends.
£225,000
Required Mortgage: £600,000
High street banks only assess drawn Salary + Dividends at 4.5× and ignore retained net profit left inside your company.
£701,635
+£476,635 indicative additional capacity vs the High Street desk
Specialist Ltd Co Insight: We assess Salary + the higher of Dividends or Post-Tax Net Profit Share (Post-Tax Net Profit Share (Retained Profits) used here). Standard lenders often ignore retained profits, penalizing the tax-efficient. Our 'Growth Award' panel does the opposite.
These figures are illustrative only, based on example income assumptions. Actual borrowing depends on your specific circumstances, full lender underwriting, and credit assessment. Lender criteria vary.
