Interest-Only mortgages in London: what to know
On an interest-only mortgage you pay only the interest each month, and the full capital remains outstanding at the end of the term. Monthly payments are substantially lower, but you must have a credible, evidenced plan to repay the capital. Lenders scrutinise that repayment strategy closely. Interest-only remains standard for buy-to-let, and is available on residential terms in London for borrowers who meet stricter equity and income requirements.
- Residential interest-only lending requires an approved repayment vehicle — investments, pension lump sum, or the sale of another property. "I will sell this house" is accepted only by some lenders and usually with substantial equity.
- Lenders generally require significantly more equity than for repayment, commonly capping interest-only at 50–75% loan-to-value.
- The total interest paid over the term is far higher than on a repayment mortgage, because the balance never reduces.
- Part-and-part arrangements, where some of the loan is repayment and some interest-only, are widely available and often a sensible compromise.
What matters locally in London
The capital is really dozens of separate markets. Zone 1 and the prime central boroughs are dominated by flats and cash-heavy buyers; the inner ring — Hackney, Peckham, Walthamstow, Brixton — mixes Victorian terraces with converted flats and heavy first-time-buyer demand; the outer boroughs from Croydon and Bromley to Barnet and Bexley are where family houses and school catchments drive moves. Ex-local-authority flats are everywhere and are perfectly mortgageable, but a minority of lenders restrict them by block height, balcony access or the percentage of privately owned flats in the block. New-build towers along the river and in regeneration zones bring their own issues: service charges that affect affordability, and cladding and building-safety documentation that a lender will want to see before offering.
- Complex and variable income. Bonuses, commission, share awards, LLP partnership drawings, contractor day rates and dual-currency pay are all common in London and are treated very differently from lender to lender — some count 100% of a bonus, others half, others only after two years of history.
- Leasehold flats. Lease length, ground rent structure, service charges and building-safety paperwork can all restrict lender choice, and a short lease is a mortgage problem long before it becomes a legal one.
Can a London broker help if I am buying an ex-local-authority flat?
Yes, and it is one of the more useful things a broker does here. Ex-council flats are mainstream security for most lenders, but a minority apply restrictions — on blocks above a certain number of storeys, on deck or balcony access, or where the majority of flats in the block are still council-owned. Knowing which lenders apply which restriction avoids a valuation being downvalued or the case being declined weeks in.
Questions worth asking a interest-only broker
- Can I still get an interest-only mortgage in London?
- Yes, though residential interest-only has tighter criteria than before the financial crisis. You will need a credible repayment strategy, a lower loan-to-value and usually a higher income. Buy-to-let interest-only remains routine.
- What counts as an acceptable repayment strategy?
- Commonly ISAs and other investments, pension lump sums, the sale of a second property, or an endowment. Some lenders accept the sale of the mortgaged property itself, but usually only where there is substantial equity.
- What happens if my repayment plan falls short?
- You remain liable for the outstanding balance at the end of the term. Options include extending the term, switching to repayment, remortgaging or selling. Speaking to your lender early gives you far more room to manoeuvre.
- Is interest-only cheaper overall?
- The monthly payment is lower, but the total cost over the term is higher because you never reduce the capital and so pay interest on the full amount throughout.
