Portfolio lending
Portfolio landlord finance

Funding for landlords past the four-property threshold, where the whole portfolio is underwritten, not just the property being bought.
What it is
Four properties changes how you are underwritten.
Under Prudential Regulation Authority rules, once you have four or more mortgaged buy-to-let properties you are treated as a portfolio landlord. From that point a lender cannot look only at the property being financed – it has to assess the whole portfolio, including its overall borrowing, rental income and how it performs under a stress test.
Expect the paperwork to increase. Most lenders ask for a full portfolio schedule (properties, values, loans, rents and lenders), an asset and liability statement, a short business plan and a cashflow forecast. Having these ready, accurate and consistent with each other is often the difference between a quick decision and weeks of questions.
There is a strategic choice to make: keep lending property by property, or move to a single portfolio facility. Separate loans give flexibility and let you sell or refinance one property without touching the rest. A single facility gives you one lender, one review date and portfolio-wide cover – but usually with cross-collateralisation, so every property supports the whole debt.
Use cases
Where a portfolio approach helps.
Consolidating multiple lenders
Bringing scattered single-property loans under one facility with one lender and one review date.
Releasing equity across the portfolio
Raising the deposit for the next acquisition from aggregate equity rather than remortgaging one property to its limit.
Failing the stress test on one asset
Using portfolio-wide cover where a single property falls short on its own.
Incorporating into an SPV
Moving personally held properties into a limited company and refinancing in the company's name. Take tax advice first – there can be capital gains tax and stamp duty consequences.
Mixed residential and commercial holdings
Portfolios containing HMOs, MUFBs and commercial units reviewed and funded together.
Buying a portfolio in one transaction
Funding a block purchase from a retiring landlord under a single facility.
Key criteria
What lenders assess.
| Measure | Typical position |
|---|---|
| Portfolio definition | Four or more mortgaged buy-to-let properties |
| Maximum portfolio LTV | Assessed on aggregate borrowing across the portfolio |
| Portfolio interest cover | Rental income must cover stressed payments across all assets |
| Documentation | Portfolio schedule, asset and liability statement, business plan, cashflow forecast |
| Facility structure | Single facility or individual loans |
| Minimum portfolio size | Lender-dependent |
Aggregate leverage across the portfolio decides more of these deals than the individual property does.
Go deeper
Underwritten like commercial lending.
Once a portfolio reaches a certain size, it is underwritten much like commercial lending: on aggregate income, cover and the strength of the landlord. Read our commercial mortgage guide for how that works, and use the affordability calculator to test the portfolio's rental cover before you apply.
