Buy a tenanted lot at auction and you become the landlord at completion, on the tenancy’s existing terms, whatever they are. The rent from completion day is yours, the obligations are yours the same morning, and the tenancy in the legal pack can move the lot’s value by six figures. This is general information rather than legal advice.
What transfers on completion
The tenancy transfers as it stands: same rent, same terms, same tenant. Under the standard auction conditions, income and outgoings are apportioned at completion, so if the tenant paid £950 on the first of a 30-day month and you complete on the 19th, the completion statement credits you £380 for your 12 days. Responsibility for the tenancy deposit also lands on you, so the legal pack should show the protection certificate and prescribed information; if it cannot, price in the risk that you inherit someone else’s breach.
Check which tenancy is actually in the pack
The new default is assured periodic tenancies
Since 1 May 2026 ordinary lets in England are assured periodic tenancies, the post Renters’ Rights Act form: monthly periodic, no fixed term to wait out. That is what most tenanted lots now carry, and it is a known quantity.
The trap is a regulated tenancy from before 1989
The trap is the regulated tenancy, which is why older tenanted lots sell cheap. Tenancies that began before 15 January 1989 fall under the Rent Act 1977, and the government’s rent officer guidance confirms regulated tenants have increased protection from eviction and can apply for a registered fair rent, which is usually well below market. A regulated tenant can effectively stay for life, on a capped rent, with succession rights in some cases. A lot like that is a long-hold investment at a low yield, not a doer-upper with a delay, and it is worth substantially less than vacant possession. Check the tenancy start date in the pack, and check the rent register if anything looks pre-1989. Our separate articles on sitting tenants and on reading an auction legal pack cover the checks in detail.
Your obligations start immediately, and so do the limits
The Renters’ Rights Act regime binds you from day one of ownership. Under the government’s landlord guidance, you cannot evict a tenant in order to sell or move in during the first 12 months of the tenancy, and that clock runs from the tenancy’s start, not from your purchase. The selling ground carries a four-month notice period, and using it blocks re-letting or re-marketing the property for a further 12 months after that notice expires, so the restriction runs to at least 16 months in total from the day it is served. Breaching it is a criminal offence that can trigger a civil penalty of up to £40,000 or a rent repayment order, so buying tenanted and quickly flipping to vacant possession is not a plan the law supports; buy the lot for the tenancy it has.

Compliance certificates from day one
Budget for immediate compliance as well. Gas safety, electrical certificates and the EPC all need to be in place and in date from the day you own the property, so check what the legal pack contains and price the gaps; our separate article on EPC rules for rental properties covers the standard required.
Price the tenancy, not the bricks
Value a tenanted lot on the rent actually passing, evidenced by a rent schedule or bank statements in the pack, not on the rent the catalogue says is achievable. If the passing rent is £950 and similar vacant properties fetch £1,150, the gap is not free money, it is a negotiation that now happens on the tenant’s statutory terms and timetable.
The clean test before bidding: tenancy agreement in the pack, deposit certificate in the pack, rent evidence in the pack. Two out of three is a discount, not a detail. If you are bidding on a tenanted lot this month, line up a conveyancer who handles tenanted purchases before auction day, because the questions above need answers before the hammer, not after.
FAQs
Can I inherit a tenant's deposit dispute if the protection wasn't done properly?
Yes — if the previous landlord failed to protect the deposit or serve the prescribed information correctly, that liability can pass to you as the new landlord, so unresolved deposit protection in the legal pack is worth pricing in or walking away from.
Does buying at auction reset the 12-month no-eviction protection?
No — the 12-month clock runs from when the tenancy started, not from your purchase, so if a tenant has already been in place for 10 months when you buy, you'd only need to wait 2 more months before the selling or moving-in grounds become available.
What if the legal pack doesn't include a tenancy agreement at all?
Treat it as a serious warning sign rather than a technicality — without a written agreement you can't confirm the rent, term or any special terms you're inheriting, so get your conveyancer to chase it before you bid, not after.
