The situation
A buyer is considering a leasehold flat at £620,000. The latest service-charge budget is higher than the previous year and the managing agent mentions planned works. The buyer wants to keep monthly costs comfortable and avoid a surprise bill after completion.
What makes this more involved?
The property listing may not contain the full lease, service-charge history or future works position. A mortgage valuation is for the lender’s purposes and does not replace the buyer’s legal or surveying advice.
How I would approach it
Budget beyond the mortgage
Include confirmed service charges, ground rent where applicable, insurance arrangements and other household costs. Ask how the budget changes if charges increase.
Coordinate the property evidence
Ask the conveyancer to review the lease and management pack and investigate planned works, disputes and relevant building-safety information.
Keep the lender informed
Ensure material findings reach the lender through the appropriate process. A price reduction or changed deposit should be reflected in the mortgage application.
What could change the plan?
Does a mortgage offer mean the future bills are acceptable?
No. The buyer still needs to understand the legal documents, works position and personal affordability.
What if the service-charge figure is disputed?
Resolve the evidence through the managing agent and conveyancer. Do not use an unsupported lower number to make the budget fit.
What this would establish
Assess the total cost and unresolved property questions before deciding whether the flat fits the buyer’s budget and priorities.
Is the mortgage payment the whole monthly housing cost?
No. Leasehold charges and other ownership costs can be significant and should be included in the budget.
