Buy-to-Let

Buying an investment property? Here's what's different.

A buy-to-let or second home purchase runs through the same legal process as any other conveyancing transaction, but the Stamp Duty surcharge, the way you're structuring the purchase, and any existing tenancy all need handling correctly from the outset. Here's what changes.

Stamp Duty

The additional-property surcharge, briefly.

If you already own a residential property anywhere in the world, buying another one — whether it's a buy-to-let, a holiday home, or simply a second home — generally means an additional-property Stamp Duty Land Tax surcharge is added on top of the standard SDLT bands. It applies to the whole purchase price, not just the amount above a threshold, so it's worth building into your budget before you commit to a purchase price rather than discovering it at exchange.

Stamp Duty rules, rates and thresholds can change, and individual circumstances vary — this is a general guide, not tax advice specific to your purchase. Tell us it's a second property in the quote calculator below and we'll factor the surcharge into your figures automatically.

Investor reviewing a buy-to-let property purchase with a solicitor

Buying Through A Company

Purchasing through a limited company or SPV.

Many landlords choose to buy investment property through a limited company, often a special purpose vehicle set up solely to hold the property, rather than in their own name. The reasons are usually to do with how mortgage interest and profit are treated for tax purposes and how the property sits within a wider portfolio — decisions best made with your accountant, not your conveyancer.

What we do need to handle is the extra legal work a company purchase brings: confirming the company is properly registered and in good standing through a company search, and where the lender requires it, arranging the director guarantees that personally back the mortgage. Our quote itemises this separately rather than folding it into a standard purchase fee.

Where you're buying through a company, our calculator adds a fixed fee for the company search, plus a fee per director guarantee, alongside our standard purchase fee.

Sitting Tenants

Completing on a property with tenants already in place.

Buying a tenanted investment property doesn't reset the tenancy — the existing tenancy agreement, deposit protection, and any notices already served generally continue to apply to you as the new landlord once you complete. Before exchange, we review the tenancy agreement and confirm which type it is, check whether the deposit is correctly protected in a government-approved scheme, and check the status of any notices that have been served.

Around completion, we make sure the right paperwork passes to you: notice of the change of landlord for the tenant, and confirmation of where the deposit is held, so you can pick up the tenancy correctly rather than untangling it after the keys have changed hands.

Why It Costs More

Why we add a fixed buy-to-let fee.

An investment purchase brings extra checks that a standard owner-occupier purchase doesn't, so we price that work openly as a fixed addition rather than leaving it to surface later. Here's what's covered.

Fixed Fee

Buy-to-let / second home

£150 to cover the additional-property SDLT calculation and the extra care an investment purchase needs throughout.

If Buying Via A Company

Limited company purchase

£100 for the extra work involved in a company, rather than personal, purchase.

Per Director

Director guarantee

£150 per director where your lender requires a personal guarantee behind the company mortgage.

Disbursement

Company search

£45 to confirm the purchasing company is properly registered and in good standing.

If you already own a residential property anywhere in the world and you're purchasing another one, the additional-property surcharge is generally added on top of the standard SDLT bands, even if the new property will be let out rather than lived in. There are limited exceptions, such as replacing your only or main residence. This is general information, not tax advice on your specific purchase.

Yes, it typically involves more work than a straightforward personal purchase. Our fee reflects company searches to confirm the company is properly registered and in good standing, plus checks around any director guarantees the lender may require, on top of the usual purchase conveyancing.

The tenancy doesn't simply end because the property changes hands. Your conveyancer reviews the existing tenancy agreement, checks any deposit protection and notices already served, and makes sure the right paperwork is served or transferred around completion so the tenancy continues correctly under the new ownership.

Investment purchases carry extra checks that a standard owner-occupier purchase doesn't: the additional-property SDLT calculation, and where relevant, company searches and director guarantee checks. We add a fixed buy-to-let/second-home fee to cover this rather than treating it as a standard purchase and adding costs later.
