A management budget should show what you expect to pay, when it is due and what evidence supports the estimate. Start with your property's actual agreements and condition rather than an industry percentage presented as a universal rule.
Read the agent quotation line by line
Ask for the total charge, whether VAT is included and which services cost extra. Check setup, inspections, inventories, maintenance administration and the cost of ending the appointment. Record the charging basis: a percentage of rent collected differs from a fixed monthly fee.
Separate recurring and occasional costs
List regular bills alongside planned works, replacement items and costs linked to a change of tenancy. For each estimate, record the quotation date and what is included. An annual planning allowance is not the same as money already paid or a contractor's promise to complete work.
Allow for uncertainty
Prepare a second scenario with a rent gap and an unexpected repair. Choose assumptions you can explain, and update them as the property's history develops. Do not count a reserve transfer and the eventual repair invoice as two separate operating costs in the same comparison.
Keep tax and cash planning distinct
HMRC's rules determine which expenses are allowable for tax; the fact that a payment appears in your budget does not settle its treatment. Review financing, tax and capital spending separately with the relevant adviser before treating a projected balance as spendable profit.
