Unfortunately, the wider economy is going to play havoc with your best-laid plans. Inflation is the killer of even the best of budgets. But if you understand its consequences you can plan for it within your budget.
I get that you’re a property manager, not an economist. But even so, the economy is going to have a major impact on your job. It’s out of your control, but inflation is going to have to factor massively into your plans.
Inflation is a persistent increase in the general price level of goods and services over time, resulting in a decrease in purchasing power.
