Landlord & investor
Finance structured around the whole property business
Once a landlord owns several mortgaged properties, the lender may assess the complete portfolio rather than viewing the new property in isolation. Corporate structures can add further layers, including SPVs, trading companies, LLPs, group ownership and multiple directors. ERG Finance prepares the business and portfolio information so it can be underwritten coherently.
We will assess your complete circumstances, explain the available routes and recommend a mortgage that supports your wider plans. Your initial conversation is without obligation.

What makes a portfolio landlord?
The Prudential Regulation Authority defines portfolio landlords for underwriting purposes as borrowers with four or more mortgaged buy-to-let properties. Lenders can apply additional definitions and count properties held solely, jointly or through companies connected to the applicants. Specialist underwriting normally reviews both the proposed mortgage and the aggregate portfolio.
Who this may help
We help established landlords purchasing or refinancing several properties, SPVs with growing portfolios, family property companies, LLPs, investors seeking multi-property facilities and clients whose existing portfolio contains a mixture of personally and company-owned property, HMOs, multi-unit blocks or commercial elements.
What needs to be considered
- Aggregate portfolio loan-to-value and ICR
- Individual properties with weak rent, high leverage or short leases
- Property schedule accuracy and ownership across personal and company names
- Geographic, tenant or development concentration
- Directors, shareholders, guarantees and group structure
- Portfolio bank statements, accounts, tax calculations and business plans
- Cash flow, voids, arrears and upcoming product maturities
- Maximum exposure with one lender or banking group
- Whether a multi-property application, facility or separate loans is most suitable
How ERG Finance approaches it
We reconcile the property schedule against mortgages, rents and ownership before approaching a lender. We identify weak points, model the new borrowing and package the wider portfolio narrative. This can include refinancing underperforming debt, releasing equity, consolidating maturities or separating specialist assets from standard properties.
Portfolio stress testing
A new property may pass its own rental calculation while the existing portfolio fails the lender’s aggregate test. Lenders can apply an overall ICR and maximum portfolio LTV using stressed interest on every mortgage, including properties financed elsewhere. Mixed personal and company ownership may be tested differently. The portfolio should therefore be checked before costs are incurred on the new application.
Our role
- understand the purpose of the mortgage and the outcome you need
- check affordability, lender criteria and property requirements before recommending a route
- compare the rate, fees, flexibility, early repayment charges and overall cost
- prepare the application and evidence so the lender sees a complete and accurate case
- manage the mortgage process through valuation, offer and completion
Frequently Asked Questions
-
The regulatory definition refers to four or more mortgaged buy-to-let properties. Individual lenders may count applications and connected ownership differently, so the complete position must be checked.
-
Typically a detailed property schedule, mortgage balances, rents, values, product details and ownership. Accounts, tax documents, bank statements, business plans or cash-flow forecasts may also be requested.
-
It can affect an aggregate ICR or LTV calculation. Some lenders take a portfolio-wide view, while others focus more heavily on the new security.
-
Some lenders accept trading companies, but many standard limited-company products require an SPV. The business activity, accounts, ownership and liabilities need individual assessment.
-
A smaller specialist lender panel can consider LLPs. Members, guarantees, tax treatment and portfolio criteria all require review.
-
Potentially. Multi-property applications or facilities can simplify funding, although cross-collateralisation, fees and future flexibility should be understood.
