How it works

You buy a property below market value because it needs work, carry out the renovation, and sell at the improved value. The profit is the spread between purchase plus renovation plus holding costs, and the eventual sale price. Every month it takes longer than planned eats directly into that spread.

How to start

  1. 01

    Know the after-repair value before you buy

    Everything depends on this number. It comes from recent comparable sales in the same streets, not from asking prices or optimism.

  2. 02

    Cost the renovation with contractor quotes

    Estimate from actual quotes, then add 20% contingency. The overrun is not a possibility, it is the base case.

  3. 03

    Apply a hard purchase rule

    A widely used guideline is paying no more than about 70% of after-repair value minus renovation cost. The discipline is in walking away when a deal fails it.

  4. 04

    Line up financing before offering

    Conventional mortgages rarely fund properties needing major work. Short-term lending is expensive, which makes speed the whole game.

  5. 05

    Manage the timeline aggressively

    Interest, insurance, utilities and taxes accrue every month you hold it. A three-month overrun can consume the entire profit.

  6. 06

    Renovate for the buyer, not for yourself

    Fit the finish to the neighbourhood. Over-improving relative to the street is the most common way a technically successful renovation loses money.

Honest trade-offs

What works

  • Large single profits realised in months rather than years
  • Skills and contractor relationships compound across projects
  • No tenants, no long-term management, no ongoing landlord obligations
  • Genuine value creation rather than reliance on market movement

What does not

  • Highest risk in property — a bad flip can lose your entire capital
  • Requires substantial cash or expensive short-term borrowing
  • Effectively a full-time job during each project
  • Profits are usually taxed as trading income rather than capital gains

Risks and failure modes

  • Renovation overruns in cost or time, which is the normal outcome rather than the exception
  • Market softening between purchase and sale, removing the margin entirely
  • Hidden structural, damp or electrical problems discovered after purchase
  • Holding costs accumulating on a property that will not sell at the expected price

Common questions

Experienced flippers target $20,000–$60,000 per project on typical residential properties, aiming for 10–20% of the after-repair value. Beginners frequently make far less or lose money, usually because renovation was underestimated and the timeline slipped.

The strategies marketed as no-money flipping generally mean expensive borrowing or partnering with someone who provides capital while you provide work. Both are real; neither removes risk, and borrowing at high rates magnifies the consequences of a slow sale.

They are different businesses. Flipping is an active trade that generates income and stops when you stop. Renting is slower but accumulates assets and passive cash flow. Many investors flip to build the capital that funds rentals they keep.
