| Tool | Description | Behaviour |
|---|---|---|
| analyse_buy_to_let_deal | Full UK buy-to-let analysis for a purchase price and monthly rent: gross and true net yield after service charge, ground rent, agent fees, repairs, voids and mortgage interest, Section 24 tax, monthly cashflow before and after tax, break-even mortgage rate, a 0 to 100 deal score, and stress scenarios such as a rate shock, a recession and extended voids. Agent fee, repairs and voids the user has not given take standard assumptions, listed in assumptions_applied. Returns a link that opens the same deal in the calculator. | Read-only |
| calculate_btl_mortgage | Calculates a UK buy-to-let mortgage: loan amount, loan-to-value, monthly and annual payment (interest-only or repayment), total interest, the interest coverage ratio lenders test against rent, and stress-test results at higher rates. | Read-only |
| calculate_capital_gains_tax | Estimates UK capital gains tax on selling a rental property, shares or another asset: gain after allowable costs, private residence relief where it applied, the annual exempt amount, tax at basic and higher rates based on the seller's income, and how much a joint sale with a spouse or civil partner would save. | Read-only |
| calculate_section_24_tax | Works out a UK landlord's income tax on rental profit under Section 24, where mortgage interest is not deductible and is replaced by a 20% tax credit. Returns the tax bill, the 20% credit, cashflow after tax, the extra tax compared with full interest relief, and the same figures for all three tax bands. | Read-only |
| calculate_stamp_duty | Calculates Stamp Duty Land Tax for a property purchase in England or Northern Ireland at current rates, with the band-by-band breakdown, the effective rate, a comparison across first-time buyer, home mover and additional-property (buy-to-let, 5% surcharge) rates, and the total cash needed with the deposit. | Read-only |
| check_deal | Checks a specific buy-to-let property in England or Wales from its postcode, asking price, type and bedrooms, using live public data: sold prices nearby and a price guide based on them, rent (the area average unless given), true net yield and cashflow, stress tests, crime, flood risk and live warnings, coal mining, planning constraints (conservation areas, Article 4, listed buildings), transport, schools and the local rental market. The postcode is the property's, not the user's location. Returns a 0 to 100 score with its parts, flags, a rule-based summary and a link to the full report. Results are educational estimates, not financial advice. Needs the user to sign in to their RealYield account; takes up to 30 seconds. | Read-only |
| compare_personal_vs_company_ownership | Compares the annual tax on a UK rental property held personally (Section 24 rules) against holding it in a limited company (corporation tax, then dividend tax on profit extracted). Returns net profit and effective tax rate for each structure and which one pays less this year. | Read-only |
| define_property_term | Looks up a UK property investment or landlord tax term in the RealYield glossary, for example 'ICR', 'Section 24', 'gross yield' or 'void period', and returns the definition with a link to the full entry. Use it when a reader asks what a term in an article means. | Read-only |
| list_realyield_calculators | Lists every UK property calculator on realyield.co.uk with a one-line description and URL. Use it to find the right tool for a landlord question before navigating or calculating. | Read-only |
| lookup_area_rental_yields | Looks up average rent, average price and gross rental yield for local authority areas in England and Wales, from ONS rents and HM Land Registry prices updated monthly. Pass an area name to get its figures and national rank, or leave it out to get the highest-yielding areas, optionally within a region. | Read-only |
| search_realyield | Searches realyield.co.uk for calculators, articles, glossary terms and downloadable templates about UK buy-to-let, landlord tax and property regulation. Returns titles, summaries and URLs. | Read-only |
