HMO Refurbishment Mortgages | Staged Funding from 6.2% (2026)

A refurbishment HMO mortgage (or bridge-to-term structure) funds purchase and renovation of a property you intend to let as an HMO. Funds may release in stages against works. Short-term bridging is common for the works phase, then refinance onto a long-term HMO mortgage once licensed and tenanted. Lenders want a clear works budget and exit plan.

Covered works typically include structural repairs, room conversions, and HMO-specific safety upgrades. Most lenders also cover kitchen and bathroom installations, fire safety improvements, and electrical upgrades.

Lenders release funds in tranches — typically at purchase (e.g. 70% of price) then further draws after inspection of completed works. Each draw requires evidence of progress, often a QS or valuer sign-off. Retained interest can be deducted from the loan so you are not paying monthly from cash flow during the build.

Bridging/refurbishment rates are often 0.55%–1.1% per month rolled up, equivalent to roughly 6.5%–13% annualised depending on LTV and experience. Term HMO rates after refurbishment align with standard HMO products (often 5%–7% fixed). Model the blended cost across bridge plus exit mortgage.

Bridging or refurbishment structures often require 30–35% equity in the project (purchase plus works), with total lending capped at 65–70% of GDV. On a £200,000 purchase plus £60,000 works, you might need £70,000–£90,000 cash depending on lender caps. Experienced developers sometimes access slightly higher leverage.

Your lender instructs a valuation through their panel — you cannot usually choose an independent surveyor for mortgage purposes. For your own due diligence, commission a RICS Level 2 or 3 survey plus a rental assessment. HMO investors often add fire-risk and licensing compliance reviews before purchase.

You need a clear works budget, acceptable credit, relevant experience or a credible contractor, planning/building regs route if required, and a defined exit (refinance or sale). Lenders cap LTV on GDV and may refuse properties in poor structural condition without contingency. Valid HMO licensing path post-works is essential.

Bridging on purchase can complete in 2–4 weeks; full refurbishment-to-term journeys often run 4–9 months including works. Allow time for staged inspections between drawdowns. Having QS documentation and contractor contracts ready prevents delays.

Purchase leg: ID, proof of deposit, property details, works schedule and costs, planning permission if needed, contractor quotes, and exit strategy. Each drawdown needs evidence of completed stages. Refinance leg: licence, tenancy schedule, completion photos, and building control sign-off where applicable.

Planning and professional fees are usually paid from your equity rather than financed directly, though they form part of your overall project budget. Some development-style facilities include professional fees within total project cost caps. Keep fee invoices for lender monitoring and tax records.
