How to monitor an investment property managed by an agent

To monitor a property your agent manages, check three things on a regular cycle. First, that the money on each agent statement matches what reached your bank. Second, that costs are expected, approved and evidenced. Third, that the property's overall performance still fits your plan. A monthly statement check, a quarterly cost review and an annual performance review, with your decisions written down, covers most of it.

The agent runs the property day to day. You keep the oversight. This guide gives you a routine, a worked reconciliation and a simple decision record you can copy. For the wider picture, see our guide for hands-off investors.

Why monitoring still matters when an agent manages

Using an agent removes most of the routine work, but it does not change who owns the property or who carries the risk. In England, many legal duties stay with you as the landlord even when an agent carries them out, as our article on how hands-off property investment can really be explains. Tax on your rental profit is also your responsibility.

Monitoring is not about distrust. Statements contain errors, fees change, small repairs add up, and certificates expire. A short, regular check catches these early.

What to gather before you start

Keep these in one place for each property:

• the agency agreement, including the fee schedule and the agent's repair spending limit
• the tenancy details: rent, payment date, start date and the deposit scheme reference
• the last 12 months of agent statements
• bank statements for the account the agent pays into (a separate account for property income makes this much easier)
• your mortgage details, including the monthly payment and when any fixed rate ends
• current certificates and their expiry dates
• insurance, service charge and ground rent details, if they apply

Step 1: reconcile agent statements with your bank

What a good statement shows

A clear agent statement should show, for each period:

• the rent due and the rent actually received
• the management fee and how it was calculated, including VAT
• each deduction, such as repairs or certificates, with a description and invoice reference
• any arrears
• the net amount paid to you and the date it was paid

If your statements do not show this, ask the agent for a clearer format.

The monthly check

1. Rent. Does the rent charged match the tenancy? If the rent has gone up, does the new figure match the agreed increase?
2. Rent received. Was the full rent paid? Note any shortfall as arrears and check what the agent is doing about it.
3. Fee. Recalculate the management fee using the rate in your agreement. Check whether it is charged on rent due or rent received, and whether VAT is included.
4. Deductions. Is every deduction backed by an invoice? Was it within the agent's spending limit, or did you approve it?
5. Net payment. Rent received minus the fee minus deductions should equal the net payment on the statement.
6. Bank. Does the net payment match the amount and date of the credit in your bank account?
7. Record. Record the rent received and each fee and deduction separately, not just the net amount. HMRC treats letting agent and management fees as allowable expenses, so a net-only record understates both income and costs.

Illustrative example: one month's reconciliation

This is an illustrative example with invented figures. It is not a typical or recommended fee level.

Assumptions: rent £1,100 a month; management fee 12% of rent received including VAT (illustrative only); one plumbing repair of £180 arranged by the agent; mortgage £520 a month (interest only), paid from your own account; landlord insurance £25 a month, paid from your own account; full rent paid this month.

Your bank shows a credit of £758.00 from the agent. That is £30.00 less than the statement. You email the agent, quoting the statement date and both figures, and ask for the reason and any invoice. The agent replies that an inspection fee of £30.00 was deducted but left off the statement, and sends a corrected statement. You check your agreement to confirm that inspection fee is chargeable, then record it as a separate cost.

Your cash flow for the month, using the corrected figures:

Cash flow here means rent received minus mortgage payments and operating costs. It is before personal tax. The mortgage and insurance do not appear on the agent's statement, which is why the statement alone does not tell you what the property is making. Our article on how much your rental property is really making goes further on this.

Step 2: watch how costs move

One month tells you little. Costs become useful when you compare them over time. Each quarter, total your costs by category and compare them with the same period last year:

A rising cost is not always a problem. Older boilers need more attention, and some work prevents bigger bills later. What matters is that you know why costs are moving and that the property still meets your goals.

If repairs are frequent, ask the agent whether a larger job would be better value, and ask for more than one quote on work above your spending limit.

Step 3: check compliance evidence

You do not need to do the compliance work yourself, but you should be able to see it was done. For a property in England, keep a copy of, and the renewal date for:

• Gas safety record. Annual check by a Gas Safe registered engineer. HSE advises landlords who use an agent to ask for copies of safety records and maintenance information.
• Electrical installation condition report. At least every 5 years, with any required remedial work done within 28 days or sooner if the report says so.
• Deposit protection. Protected in a government-approved scheme within 30 days of receipt (England and Wales).
• Energy Performance Certificate, and evidence that smoke and carbon monoxide alarms are in place.
• Renters' Rights Act paperwork (England). From 1 May 2026, tenancies are periodic and rent can be increased only once a year using the section 13 process with at least 2 months' notice. Landlords also had to give existing tenants the government's information sheet by 31 May 2026. Ask your agent for confirmation that this was done.

If your property is in Scotland, Wales or Northern Ireland, check the relevant government's guidance, as the rules differ.

Step 4: run regular performance reviews

A review is a short, scheduled look at the whole picture, not just one statement.

For the annual review, keep your definitions consistent each year:

• Gross yield = annual rent ÷ property value × 100.
• Net yield = (annual rent minus operating costs, excluding the mortgage) ÷ property value × 100.
• Cash flow = rent received minus mortgage payments and operating costs, before personal tax.
• Capital growth = change in the property's value. Keep it separate from cash flow.

Judge the agent too. Were statements accurate and on time? Were repairs handled promptly and at a sensible cost? Did they tell you about problems before you found them? In England, check they still belong to a client money protection scheme (if they hold your rent or deposits) and a government-approved redress scheme. They must display these memberships and publish their fees.

If you own several properties, reviewing them together on the same basis shows which ones are pulling their weight. Our article on portfolio tracking versus spreadsheets compares ways to do that.

Step 5: keep a decision record

A decision record is a short, dated note of what you decided and why. It helps you remember your reasoning, gives your accountant or co-owner context, and makes the next review faster. Keep one line per decision.

Illustrative example (invented entries):

When you come to decide whether to keep, refinance or sell the property, this record shows how you got there.

When to escalate

If a problem keeps happening, raise it with the agent in writing and keep copies. If that does not resolve it, use the agent's formal complaints procedure. In England, you can then take the complaint to the government-approved redress scheme the agent belongs to. If money the agent held for you is not paid over, their client money protection scheme may be relevant. If you decide to change agents, check your agreement's notice period and any fees first.

How PROXERA can help

Monitoring is easier when every property's rent, costs, mortgage and certificates are in one place. PROXERA lets you record each property, its rent and costs, mortgages and fixed-rate end dates, and documents and certificates with reminders, then see performance across your portfolio. Add your agent-managed property and enter the figures from each statement as part of your monthly check.
