Buy, refurbish, refinance, rent (BRRR)

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

Professional analysis

Key sensitivities: lender's post-works valuation (not your estimate), refinance LTV, lender seasoning rules (some require 6 months' ownership), and rental stress at the refinance rate. Track money left in deal and post-refi ICR.

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.

Financial calculations

Bridging interest, council tax, insurance, utilities.

Use sold evidence. A lender may value lower.
