For buy-to-let investors, buying a property with a “tenant in situ” (a tenant already living there) has always been an attractive proposition. It offers immediate rental income from day one, no void periods, and a property that is already set up for rental standards.
However, the investment landscape has changed. With the Renters’ Rights Act (formerly the Renters Reform Bill) now fully influencing the market in 2026, the rules of the game are different.
If you are considering buying a tenanted property this year, here is your essential due diligence guide to ensuring your investment is legally sound and profitable.
1. The End of Section 21: A New Reality
The most significant change for landlords in 2026 is the abolition of Section 21 “no-fault” evictions.
In the past, if you bought a property with a tenant and later decided you wanted to sell or move in yourself, you could serve a two-month notice without giving a reason. This is no longer possible.
Under the new rules:
- All tenancies are now periodic (rolling). Fixed-term tenancies (e.g., locking a tenant in for 12 months) have effectively been replaced.
- To regain possession, you must use Section 8 grounds (e.g., if you want to sell the property or move in).
- Crucially: You typically cannot use the “selling” or “moving in” grounds within the first 12 months of a tenancy.
What this means for buyers: When you buy with a tenant in situ, you are inheriting the existing tenancy history. You need to verify exactly when the tenancy started. If you plan to renovate and flip the property quickly, a sitting tenant may prevent you from doing so.

2. Due Diligence: The Paperwork Trail
When you buy a home for yourself, you check the bricks and mortar. When you buy a tenanted investment, you must check the paperwork with equal rigour. If the previous landlord failed to serve the correct documents, you might find yourself unable to evict a non-paying tenant later.
Your solicitor must verify that the current tenant received:
- The “How to Rent” Guide: The correct version for the time the tenancy started.
- Gas Safety Certificates: An unbroken chain of annual certificates.
- Deposit Protection: Proof that the tenant’s deposit was protected in a government-approved scheme within 30 days of receipt, and the “Prescribed Information” was served.
If the deposit wasn’t protected correctly by the seller, you (the buyer) could be liable for a penalty of up to three times the deposit amount.

3. EPC Ratings: The “C” Grade Target
Energy efficiency is no longer just a “nice to have”—it is a regulatory pressure point. The government’s push for all rental properties to reach an EPC Rating of C is a major factor in 2026 valuation.
If you are buying a tenanted property that is currently rated ‘D’ or ‘E’, you are effectively buying a future liability. You will likely need to upgrade insulation, heating, or windows while the tenant is living there.
- Ask: Can I access the property to do the work?
- Check: Is the price reflective of the £5,000–£10,000 you might need to spend on retrofitting?
Before you commit, it is vital to have a survey that looks specifically at energy efficiency potential. See our overview of types of homebuyer surveys to choose the right one for an older rental property.
4. Rent Apportionment and Arrears
One of the most common disputes when buying tenanted property is money.
- Rent Apportionment: If the tenant pays rent on the 1st of the month, but you complete your purchase on the 15th, the seller owes you half a month’s rent. This must be calculated and transferred by the solicitors on the completion statement.
- Arrears: NEVER complete on a purchase without a clear statement of the tenant’s rent history. If the tenant is in arrears, buying the property does not automatically give you the right to claim those historic debts unless specifically assigned in the contract.
We strongly recommend asking for a rent ledger for the last 12 months. This is the only way to verify if the “good payer” described by the estate agent is actually reliable.
5. Stamp Duty on Second Homes
Don’t forget the tax implications. Buying an investment property attracts the 3% Stamp Duty Land Tax (SDLT) surcharge on top of standard rates.
With the changes to SDLT thresholds in recent years, it is vital to calculate this accurately before you make an offer. You can find more details on current rates in our article: What is Stamp Duty and why do you need it?.
6. The Transfer Process
Once you complete the purchase, you legally step into the shoes of the landlord. You do not need a new tenancy agreement immediately (the existing one remains valid), but you must serve a “Section 48 Notice” and a “Section 3 Notice” to the tenant.
- These notices inform the tenant that you are the new owner and provide your address for service of notices.
- Failure to serve a Section 48 notice means the rent is not legally due!
Why You Need a Specialist Solicitor
Buying with a tenant in situ is not a standard conveyancing transaction. It sits at the intersection of Property Law and Landlord & Tenant Law. A standard conveyancer might miss a missing Gas Safety record from 2023, but that single piece of missing paper could prevent you from removing a problem tenant in 2027.
At Gorvins Residential, we ensure that you aren’t just buying a property—you’re buying a compliant, viable business asset.
