The situation
A landlord has a programme of repairs and energy-efficiency improvements across 15 properties. Some are personally owned and others sit in a company. They want to explore capital raising rather than pay for the entire programme from cash reserves.
What makes this more involved?
The strongest property is only one part of the picture. Existing mortgages, early repayment charges, rent, vacancies and ownership can affect which borrowing is practical. Works budgets and anticipated rent increases should not be treated as guaranteed outcomes.
How I would approach it
Prioritise the works
Separate essential repairs from discretionary upgrades, obtain costed scopes and allow for tenants, access and contingency. Confirm any professional or local-authority requirements.
Review financing property by property
Map lender, balance, fixed-rate expiry, charges, ownership and rental income. Compare whether refinancing now or staging borrowing around existing dates better fits the need.
Stress the portfolio budget
Consider lower rent, void periods, cost overruns and the new debt service. Ring-fence an operating buffer instead of spending every pound released.
What could change the plan?
Should every property be refinanced together?
Not necessarily. Existing terms and charges may make a phased approach more suitable, although each route needs its own assessment.
Can forecast higher rent support the borrowing?
The lender decides what rent and evidence it accepts. A planned increase must not be presented as existing income.
What this would establish
Choose whether and how to fund improvements while keeping the portfolio’s cash requirements visible before and after the proposed borrowing.
Does a high portfolio value guarantee capital raising?
No. Valuations, rent, debt, ownership and lender criteria all affect the available assessment.
