Property Flipping Guide: Costs, Tax & Realistic Profits

What Is Property Flipping?

Property flipping means buying a property below market value, renovating it, and selling for a profit. It's not passive income — it requires significant time, capital, and knowledge of the property market.

Typical Costs

• Purchase costs: Stamp duty (5% surcharge for additional property), solicitor (£1,000-2,000), survey (£400-800)
• Renovation: £20,000-80,000+ depending on scope
• Financing: Bridging loan interest (0.5-1.5% per month), arrangement fees
• Selling costs: Estate agent (1-2% of sale price), solicitor (£1,000-1,500), EPC
• Holding costs: Council tax, insurance, utilities during renovation

Tax Implications

Profits from flipping are taxed as income (not capital gains) if HMRC considers you're trading. This means 20-45% income tax plus NI. If you flip occasionally, CGT may apply at 18-24%. The 5% stamp duty surcharge applies to any property that isn't your sole residence.

Realistic Profit Margins

Aim for a minimum 20% profit margin on total costs to account for unexpected expenses. On a £200,000 purchase with £40,000 renovation and £20,000 in buying/selling costs, you need to sell for at least £312,000 to make a 20% return.

Common Mistakes

Overpaying for the property, underestimating renovation costs (always add 20% contingency), over-improving for the area, taking too long (holding costs eat profit), and not accounting for all taxes and fees.

Getting Started

Start with cosmetic renovations (kitchens, bathrooms, decoration) rather than structural work. Build a reliable team of tradespeople. Know your local market intimately. Have your financing arranged before you find a property.
