Property viability file

Turn a quick property result into a structured decision file.

A YieldLens UK viability file organises the key numbers, assumptions, risks, missing data, and next checks before you commit to a property, lease, rental decision, or investment.

Indicative decision-support only. Not a formal valuation or professional advice.

Why it exists

The free check gives the signal. The viability file organises the decision.

The point is not to produce generic commentary. The point is to make the key property risks harder to ignore.

Clarify the numbers

Summarise the key return, affordability, rent burden, cash flow, or break-even metrics.

Expose weak assumptions

Highlight where the result depends on optimistic rent, low costs, strong demand, or missing data.

Structure next checks

Turn the result into a practical checklist before negotiations, viewings, legal work, or further due diligence.
