Portfolio landlords live or die on coverage: rent in, mortgage and costs out, buffer left over. Lenders test it at stressed rates around 145% of mortgage payments for higher-rate taxpayers, and they read personal plus business statements together to confirm the buffer is real. A bank statement analyser aggregates recurring rental credits across accounts, totals mortgage and cost debits, and reports the coverage position month by month.
Voids show up before they hurt. A missing rental credit with standing costs continuing is the exact pattern a coverage report catches in month one rather than at remortgage. Categorised rental income versus management fees, insurance, and maintenance also separates true yield from gross rent figures that flatter a spreadsheet.
Remortgage applications go faster with prepared files. Six months of statements converted to clean Excel with the Bank Statement Analyser, plus an analyser summary showing income stability, obligation totals, and reconciled balances, answers the broker's first three questions before they are asked.
Stress-test privately first. Run the portfolio statements through the free Bank Statement Analyser, read the fixed-obligations ratio as the lender will, and fix thin months — overpayments paused, buffers rebuilt — a quarter before the product transfer window opens.
