About

LetLogiQ publishes free planning tools for UK buy-to-let and HMO property decisions. Its purpose is to make the difference between rent, profit and spendable cash easier to understand.

What the tools do

Our calculators bring together rental income, empty periods, operating costs, borrowing, purchase costs and estimated tax. You can compare personal ownership with company-retained cash, inspect cash-on-cash ROI and explore adverse scenarios.

How the content is prepared

The tools use a deterministic calculation engine and link to official tax and property guidance. Planning allowances and financial assessment weights are modelling choices. This website does not claim an independent professional tax review, and it is not an adviser or lender recommendation.

Use the results with context

Check property-specific figures with your advisers and the relevant council. Market demand, condition, legal eligibility, future tax changes and company extraction decisions are outside or beyond parts of this model. Read the methodology below each calculator and the calculation update history.
