Freehold Purchase Calculator

If you’re a flat leaseholder and interested in buying the freehold on your property, this online freehold calculator tool is an invaluable resource. It provides you with a valuable approximate range estimate of the premium costs associated with collective freehold purchase.

As a leaseholder, you may currently pay ground rent to your landlord. This cost varies depending on your agreement and can fluctuate with the current market value of your property. One of the key benefits of owning your freehold property is that you’ll no longer have to pay this ground rent, which can result in substantial savings over time.

It’s also important to note that our freehold calculator does not include an estimation of potential Stamp Duty Land Tax. This is a tax on the purchase of properties in England and Northern Ireland and can significantly impact the total cost of acquiring a freehold. By providing you with an approximate estimate of these costs, our tool lets you plan and budget effectively for your freehold purchase.

Remember, while our calculator offers a good starting point, it’s crucial to get an accurate valuation from a professional service to understand your specific costs involved fully. This can include legal fees, valuation fees, and any additional costs related to the transfer of ownership.

What Data Does Our Calculator Use?

Our freehold purchase calculator uses a mix of information you provide and market-based assumptions to generate an approximate premium range, rather than an exact valuation.

Information you enter

When you complete the form, you provide the core inputs that drive your estimate:

• The long lease value of your property (current market value of the flat as a leasehold).
• The number of years remaining on the lease.
• The annual ground rent payable under your lease.
• Any other details requested in the form, such as existing or average ground rent, purchase price, and the percentage of freehold interest.​

These figures help the calculator understand both the current value of your lease and the income and time left in the freeholder’s interest.

Market data and valuation assumptions

Alongside your own figures, the calculator uses typical valuation assumptions to estimate a likely range for the freehold premium.

• Relativity between leasehold and freehold values (how a leasehold’s value compares with an equivalent freehold).
• Typical yields used to capitalise ground rent income into a lump-sum value.
• Standard assumptions about how the property’s value may change once the freehold is purchased and the lease is extended.
• Default settings for complex variables such as marriage value, interest rates, and inflation, rather than bespoke figures for your specific building.

Because these assumptions are necessarily generic, two similar properties can receive slightly different estimates if their lease length or ground rent profile differs.

What the calculator does not include

The calculator is designed as a planning tool and does not attempt to model every possible cost or nuance.

• It does not include professional fees, legal fees, lender fees, or any potential Stamp Duty Land Tax that may be payable on your freehold purchase.
• It does not incorporate building-specific issues such as major works, defects, service charge disputes, or unusual lease terms.
• It is not intended for leases below 80 years, where marriage value and other technical valuation elements become more complex and can materially change the premium.

For these reasons, the output should be treated as an approximate guide only, not as a figure you rely on for tribunal, court, or negotiation purposes without first obtaining a professional valuation from a qualified surveyor.
