Buy, refurbish, refinance, rent (BRRR)

Add value, refinance at the new value to recycle your cash, then hold as a rental.

beginnerprofessional

In plain English

You buy a property below its potential, improve it, then remortgage based on the higher value so you can take some or all of your money back out — then rent it out. It works only if the new valuation is high enough and the rent covers the bigger mortgage.

Switch to professional for underwriting detail.

Capital requirements

Purchase plus works (cash or bridging), holding costs; the aim is to recover much of it on refinance.

Cost assumptions to budget for

  • SDLT and acquisition fees
  • Bridging interest
  • Works
  • Refinance arrangement, valuation and legal fees

Potential returns

Return on cash left in can be high if most capital is recycled — but only if valuation and rent hold up.

Main risks

  • Down-valuation on refinance
  • Refinance rates higher than planned
  • Works overruns
  • Seasoning rules delaying the refinance

Legal checks

  • Title and planning for works
  • Building regulations

Regulatory checks

  • Protect deposits in a government-approved scheme within 30 days and serve the prescribed information.
  • Right to Rent immigration checks (England).
  • Annual gas safety check; electrical installation condition report at least every 5 years; smoke and carbon monoxide alarms.
  • EPC of at least E to let (minimum energy efficiency standard). Higher future minimums have been proposed — check the current position.
  • Tenancy law in England is being reformed by the Renters' Rights Act 2025 (including ending section 21 'no-fault' evictions). Check which provisions are in force on your start date.
  • Selective or additional licensing may apply in some council areas.

A general guide, not a personal recommendation. Suitability depends on your finances, experience and attitude to risk.

Step-by-step

  1. Identify value-add (layout, condition, extension).
  2. Get comparable evidence for the end value.
  3. Run the BRRR calculator with a lower-than-hoped valuation.
  4. Confirm refinance lender criteria before buying.
  5. Complete works with sign-offs.
  6. Let the property, then refinance.
