WORK THROUGH THIS EXAMPLE
Your rental pack shows £8,000 of mortgage payments but no interest certificate. Ask for the lender’s breakdown before calculating finance-cost relief. Keep any brought-forward restriction schedule too, because the current bank total does not explain relief available from earlier years.

DECISION TO RESOLVE
What amount is interest, and what earlier restricted costs remain available?
