Buying a UK Property With Tenants In Situ: What Should You Check?

Buying a UK investment property with tenants already living in it can look straightforward. You do not need to start from scratch finding an occupier, and there is already a tenancy and rental history to assess.

But you are not simply buying the building. You are also taking over an existing landlord-and-tenant relationship, with the rights, responsibilities, paperwork and history that come with it.

So, what should you check before buying a property with tenants in situ?

What does “tenants in situ” actually mean?

A property sold with tenants in situ is being sold while the existing tenants remain in occupation.

The important point is that the tenancy does not normally disappear simply because the property changes ownership. The buyer becomes the new landlord and takes over the landlord's side of the existing tenancy. The tenant does not automatically have to sign a new agreement simply because there is a new owner.

That distinction matters.

If you buy an empty property, you can usually establish the letting arrangements yourself before a tenant moves in. If you buy a tenanted property, you need to understand the arrangement that already exists before you commit to it.

That means the tenancy itself deserves almost as much due diligence as the bricks and mortar.

1. Establish exactly what type of tenancy you are taking over

Do not rely solely on an estate agent describing the property as having a “sitting tenant”.

Ask your solicitor to establish the actual tenancy type, the date it began and the terms currently in force.

This is particularly important in England because the rental system changed significantly on 1 May 2026. Most existing assured shorthold tenancies automatically became assured periodic tenancies, and new assured private tenancies are now periodic rather than fixed-term. An old tenancy agreement may therefore still show a fixed end date even though that end date no longer determines when the tenancy finishes.

The start date matters for another reason.

Private tenancies that began before 15 January 1989 may, in some circumstances, be regulated tenancies. These can carry stronger security-of-tenure protections and different rent rules, so they require careful legal review before purchase.

If there were possession notices or court proceedings already underway before 1 May 2026, ask your conveyancer to check whether transitional rules affect the tenancy.

2. Read the tenancy documents, not just the property particulars

The advertised rent tells you very little about the legal arrangement behind it.

Before exchange, ask for the tenancy file and reconcile it against what the selling agent has told you.

At a minimum, we would want to understand:

• who the legal tenants are and when the tenancy began;

• the current rent, payment frequency and date it is due;

• when the rent was last increased;

• the tenancy agreement or other written record of its terms;

• the deposit amount and protection details;

• the rent statement and any arrears;

• the inventory and original check-in report;

• outstanding repairs, complaints or disputes;

• relevant gas, electrical and energy documentation;

• any property or HMO licensing requirements;

• relevant Right to Rent records for an English property; and

• any notices already given by either landlord or tenant.

  
  

This is not about creating paperwork for the sake of paperwork.

It is about confirming that the income, occupancy and legal position you think you are buying actually match the records.

If you are purchasing from overseas, this becomes even more important because you may not have met the tenants or managed the property yourself before completion.

For wider preparation before a UK purchase, see our guide to the documents overseas property buyers should prepare.

3. Check the rent that is actually being paid

A tenanted property may be marketed using an attractive rental figure, but you should verify what is actually being collected.

Ask for a rent statement rather than relying solely on the tenancy agreement.

Check whether payments have been made consistently, whether there are current or historic arrears, and whether the advertised annual rent genuinely reflects the tenancy you are acquiring.

You should also avoid assuming that a below-market rent can simply be increased immediately after completion.

For assured periodic tenancies in England, rent can generally be increased only once in a 12-month period, cannot be increased in the first year of the tenancy, and the landlord must use the statutory section 13 process with at least two months' notice. The tenant may ask the First-tier Tribunal to determine the open-market rent if they dispute the proposed figure.

So if your investment calculation depends on increasing the rent, check both when the tenancy started and when the last increase took effect.

Model the investment using the existing rent first. Treat any future increase as something to verify rather than assume.

4. Make sure the tenancy deposit is properly dealt with

If the tenants paid a deposit, establish:

• how much was paid;

• which authorised scheme protects it;

• whether the required information was given to the tenants; and

• exactly how responsibility for the deposit will pass from the seller to you.

For relevant tenancies, deposits must remain protected through a government-approved tenancy deposit protection scheme.

A change of property ownership does not mean the deposit can simply disappear from the process. The incoming landlord should make sure the deposit remains correctly protected and that the necessary scheme information is updated. The exact procedure can depend on which deposit scheme and protection model is being used.

Your solicitor should deal with this as part of the completion arrangements rather than leaving you to discover afterwards that the seller still holds the deposit.

5. Check the property's compliance history

You will become responsible for the property as landlord after completion, so a folder full of certificates should be checked rather than simply accepted at face value.

For an English rental property, landlords have responsibilities covering matters such as gas and electrical safety, Energy Performance Certificates, alarms, general property safety and deposit protection.

Ask for the current documents and also investigate anything outstanding.

For example, if an electrical report identified remedial work, has that work actually been completed?

If a tenant reported damp six months ago, what happened next?

If the property requires a local licence, is it currently licensed and what will happen to that licence when ownership changes?

Selective licensing can apply to privately rented properties in designated local-authority areas, so this must be checked against the specific property rather than assumed from the property type alone.

For an HMO, speak to the relevant local authority before completion. Councils make clear that HMO licences are generally tied to the licence holder and a purchaser may need to make a fresh application rather than relying on the seller's existing licence.

6. Do not overlook Right to Rent records

For properties in England, Right to Rent deserves its own place in the handover.

From 1 October 2026, updated Home Office guidance specifically addresses changes of landlord where a property is purchased with sitting occupiers.

It states that the incoming landlord should confirm with the previous landlord that the appropriate Right to Rent checks were carried out, retain evidence of those checks and identify whether any future follow-up check is required.

That makes this more than a simple question of asking, “Were the tenants referenced?”

You need the relevant evidence.

7. Review repairs, complaints and the inventory

A tenant who has lived in a property for several years may know more about its practical condition than a short viewing reveals.

Ask for the seller's maintenance records and any correspondence concerning unresolved problems.

Look for recurring issues rather than just completed jobs.

A boiler repair completed last winter may be routine. Repeated reports of leaks, mould, drainage issues or electrical faults deserve closer examination.

The inventory and check-in report are also important because they record the property's condition at the beginning of the tenancy.

If, years later, there is a dispute about damage or a proposed deposit deduction, the quality of that historic evidence may matter.

If you are arranging a viewing or inspection while the property remains occupied, remember that it is still the tenant's home. GOV.UK's home-buying guidance specifically advises prospective buyers to be respectful when visiting rented property.

8. Check whether the finance works with the existing tenancy

If you are using a mortgage, tell your broker and lender that the property is being purchased subject to an existing tenancy.

Do not assume that because it is a buy-to-let mortgage, every form of existing tenancy will automatically satisfy the lender's criteria.

GOV.UK notes that purchasing a rented property can have legal, tax and mortgage implications and recommends taking appropriate expert advice.

The same applies to insurance.

Make sure the policy you intend to use reflects the actual property, tenancy and tenant profile rather than an assumed future letting arrangement.

9. Understand what you need to do immediately after completion

The handover should be prepared before completion rather than improvised afterwards.

In England and Wales, section 3 of the Landlord and Tenant Act 1985 requires a new landlord to notify the tenant in writing of the assignment of the landlord's interest and provide the new landlord's name and address within the statutory timeframe.

For an English property, there is another point that is especially relevant to investors living overseas.

Section 48 of the Landlord and Tenant Act 1987 requires the landlord to give the tenant an address in England and Wales where notices can be served. Until that requirement is met, rent otherwise due is treated as not due for the relevant period.

Your completion handover should therefore cover more than simply sending new bank details.

The tenants need to know who their landlord or managing agent is, where rent should be paid, where notices can be served, who to contact for repairs and emergencies, and what has happened to their deposit.

For an overseas investor, having a competent UK management arrangement in place before completion can make that transition considerably easier. You can read more in our guide to UK property management for non-UK residents.

10. Do not confuse “tenanted” with “vacant possession later”

This is one of the biggest strategic checks.

If your plan requires the property to be empty shortly after purchase for refurbishment, conversion, occupation or another purpose, buying it subject to an existing tenancy may not fit that plan.

A sale does not itself end the tenancy.

In England, Section 21 “no-fault” eviction ended on 1 May 2026 for the reformed assured-tenancy regime. A landlord seeking possession must use an applicable legal ground and follow the correct Section 8 process.

If you require vacant possession, tell your solicitor before exchange and make sure the purchase contract reflects that requirement.

Do not complete a purchase subject to a tenancy on the assumption that you can simply ask the tenant to move out afterwards.

Is buying a tenanted property a good idea?

It can suit some investment strategies, but the presence of a tenant should not be treated as proof that the property is a good investment.

What matters is the quality of the underlying tenancy and the property.

A tenant who pays consistently, a well-documented tenancy, correctly protected deposit, good compliance history and well-maintained home give you a very different proposition from a property with arrears, incomplete records and unresolved maintenance issues.

The same principle applies to the financial analysis.

Use the actual existing rent, not an assumed future rent. Include the real management, maintenance, mortgage and purchase costs. Then decide whether the property still meets your own criteria.

Final thoughts

Buying a UK property with tenants already living in it means buying more than an income-producing asset.

You are taking over an existing contract, compliance history and ongoing relationship with the people who call the property home.

Before exchanging contracts, make sure your solicitor has established the tenancy type, reviewed the documents, checked the deposit position and identified any unusual legal issues. Independently review the rent history, property condition, repairs, licensing and management arrangements.

For overseas investors, good due diligence before completion can make the difference between inheriting a straightforward rental property and inheriting problems you did not price into the deal.
