Stamp Duty on a Second Property - Let to Buy

DMEL2025
Posts: 3 Newbie

Hello,
Can you please help me understand how much stamp duty I will pay in the below scenario?
I currently own a flat worth £160,000 which I live in and next year I am hoping to change it to a Let to Buy mortgage so I can purchase a new home to live in but keep my flat to rent out.
I am looking to purchase a home for around £280,000 and I will have a 10% deposit (£28k). Can you please confirm how much stamp duty I will pay considering this will be my second property?
Many thanks,
0

£18k.
The mortgage and purpose of the properties are (for now) irrelevant. As youre increasing the number of properties, you pay the additional rate stamp duty. £4k for normal SDLT plus £14k for the extra 5% = total £18k
You may be able to claim some of this back if you were to sell the flat within certain timescales, but you're keeping it as a rental, then the above is what will stand.

simple maths:
Higher rates of Stamp Duty Land Tax - GOV.UKProperty or lease premium or transfer value SDLT rate Up to £125,000 5% The next £125,000 (the portion from £125,001 to £250,000) 7% The next £675,000 (the portion from £250,001 to £925,000) 10%

Or for even simpler maths, use HMRC's calculator: Stamp Duty Land Tax Calculator (assuming you're buying in England or Northern Ireland).1

Thank you both. HMRC also states the following:
"Property
Do not include property (or part of a property) if any of the following apply:
- the property is worth less than £40,000
- it’s a mixture of residential and non-residential (like a shop with a flat above it)
- it’s ‘moveable’ like a caravan, houseboat or mobile home (unless it has become a permanent fixture)
The rules also do not apply to property you lease if either:
- your lease is for 7 years or less (on the date it was granted)
- the lease is owned by someone else and it has more than 21 years left"

Ah I see, thanks.
Annoyingly, if the transaction was switched and I already owned the £280k property, but was purchasing the £160k property, the stamp duty would be significantly less.
Is it relatively easy to add stamp duty onto a mortgage? As it's a large sum, it could impact the feasibility of retaining the current property.0 -
