PRA 2017 portfolio landlord rules — what lenders must assess
Understanding the PRA portfolio assessment framework helps you prepare a refinancing application that succeeds first time.
- The 4-property threshold: 4+ mortgaged BTL properties in total (across all lenders) at time of application triggers portfolio landlord status; properties in personal name without a mortgage do not count; limited company properties may or may not count toward the individual's total — lender policies vary
- Aggregate portfolio LTV: total outstanding mortgage balances / total market values of all mortgaged BTL properties; most lenders require below 65-75%; improve by: partial capital repayments on high-LTV properties; rising property values; selling properties to reduce aggregate leverage
- Aggregate portfolio ICR: total annual rental income from all mortgaged BTL properties / total annual interest at stressed rates across all; if below 125-145% threshold, lender may decline; improve by: bringing below-market rents to current market rent; reducing loan balances; selling weak properties
- Portfolio business plan: spreadsheet of all mortgaged BTL properties (address; value; mortgage balance; rate; maturity date; monthly rent; monthly payment; current tenancy status) plus aggregate totals and narrative; prepare and maintain before approaching lenders — saves significant delays in the application process
Cross-collateralisation, maturity staggering, and ICR management
Three practical strategies that materially affect portfolio refinancing resilience.
- Avoid cross-collateralisation: cross-collateralisation (single charge over multiple properties for one loan) reduces flexibility (consent needed to sell any cross-collateralised property); allows enforcement against all properties simultaneously; ties you to that lender; prefer individual mortgages with separate charges on each property
- Staggered maturity strategy: use a deliberate mix of 2/3/5-year fixed and tracker products so maturities fall in different years; avoids simultaneous refinancing at a single rate environment; when a product expires at unfavourable rates, you can temporarily sit on SVR while waiting for improvement — this option is only available if not all products mature simultaneously
- ICR management when refinancing ICR is insufficient: (1) increase rent to market rate if currently below market; (2) partial capital repayment to reduce loan balance; (3) extend mortgage term (capital repayment mortgages — reduces stressed monthly payment); (4) shop lenders via specialist BTL broker (different lenders apply different stressed rates and ICR thresholds); (5) sell the property; plan ICR position at least 12 months before maturity date
- ERC (Early Repayment Charges): typically 1-5% of outstanding balance if repaid within the fixed-rate period; factor into decisions to sell a property before the fixed rate expires; ERCs can significantly erode sale proceeds
Section 24, limited company refinancing, and rate product strategy
For higher-rate taxpayers with leveraged portfolios, the Section 24 interaction with interest-only refinancing is the critical strategic decision.
- Section 24 and limited company refinancing: limited companies can deduct mortgage interest in full (Section 24 does not apply); for highly leveraged higher-rate taxpaying landlords, refinancing into a limited company can significantly improve after-tax returns; however, incorporation carries one-off SDLT (investor rate on market value of each property transferred) and potential CGT costs — Incorporation Relief (Section 162 TCGA 1992) may defer CGT if the portfolio qualifies as a business
- Break-even analysis: calculate annual Section 24 tax saving in limited company structure vs. one-off SDLT + CGT costs + ongoing compliance costs; break-even is typically 3-5 years for moderately leveraged portfolios; specialist property accountant advice is essential before proceeding
- Rate product strategy: 5-year fixed provides ICR certainty for the fixed period (useful when ICR is tight); tracker/2-year fix allows benefit from rate reductions but exposes to rate rises; a deliberate mix of product terms both staggerers maturities and provides a balance of certainty and flexibility
