Spreadsheets feel free — until a missed gas safety renewal costs you £30,000. We explore when dedicated portfolio management software pays for itself.
Why spreadsheets aren't enough for landlords
Many landlords start out tracking their properties in spreadsheets. It works for one or two properties, but as your portfolio grows, the cracks start to show.
The compliance problem
Spreadsheets do not send you reminders. When your gas safety certificate is three months away from expiry, your spreadsheet stays silent. Miss a renewal and you could face fines of up to £30,000 — or worse, be unable to legally rent the property.
Prop-Pocket sends smart reminders for EICR, gas safety, EPC, deposit protection and How-To-Rent deadlines so you always act before, not after.
The financial problem
Tracking income and expenses in a spreadsheet means manual entry for every transaction, no automatic capital-and-interest split on mortgage payments, and a nightmare come tax time.
With Prop-Pocket, mortgage payments are automatically split into capital and interest, expenses are categorised, and your P&L report is always ready to share with your accountant.
