The 70% rule in house flipping is a guideline to determine the maximum price to pay for a property: Maximum Offer = (After Repair Value x 70%) – Repair Costs, ensuring a built-in profit and buffer for other expenses like closing costs and unexpected issues. It helps investors quickly assess if a fixer-upper is a viable deal by calculating a profitable purchase price based on the home's potential value after renovations (ARV).
Basically, the rule says real estate investors should pay no more than 70% of a property's after-repair value (ARV) minus the cost of the repairs necessary to renovate the home. The ARV of a property is the amount a home could sell for after flippers renovate it.
How to avoid capital gains tax on flipping houses?
HMRC doesn't consider house flips an investment, so you won't need to pay Capital Gains Tax when flipping houses and selling them on for a profit. However, there are other taxes to consider. You'll also need to think about whether you're selling it or renting it out – as rentals might be subject to CGT.

How much tax do you pay on flipping a house in the UK?
In the UK, flipping houses is usually seen as a business, meaning profits are typically subject to Income Tax (through Self Assessment) rather than Capital Gains Tax (CGT), as it's considered trading income, not investment gains. You pay tax on the profit, which is taxed at your normal income tax rates (20%, 40%, 45%), plus National Insurance, after deducting allowable expenses like renovation costs, stamp duty, and fees. While Private Residence Relief (PPR) can exempt main homes from CGT, it doesn't apply if the property was bought with the intention to sell for profit.

Red flags on a house survey signal serious, costly issues like structural problems (subsidence, large cracks, uneven floors) and major water damage/damp/mould, indicating potential foundation or roof issues. Other key warnings include outdated electrics/plumbing, hazardous materials like asbestos, pest infestations, invasive plants (Japanese knotweed), and potential boundary/legal disputes or unapproved extensions, all requiring expert assessment before purchase.
The "property 36-month rule" in the UK refers to a Capital Gains Tax (CGT) exemption for the final period of owning a main residence, though the standard exemption period for the last part of ownership has changed from 36 to 9 months for most people, with the 36-month period now applying only in specific situations like long-term care or disability. It allows tax relief on gains for the last few months (or 36 months if disabled/in care) of ownership, even if the property wasn't lived in during that final time, provided it was a main home at some point.
What is a simple trick for avoiding capital gains tax?
A common way to defer or reduce your capital gains taxes is to use tax-advantaged accounts. Retirement accounts such as 401(k) plans, and individual retirement accounts offer tax-deferred investment. You don't pay income or capital gains taxes on assets while they remain in the account.
