Step 1 of 7

Property type

Answer a few quick questions to get your estimate

Let’s get a quick understanding of your situation

What type of property are you selling?

Start with the closest match.

Most common House / Apartment Main residential property being sold Gifted or inherited in some cases Land Site, parcel, or non-residential land Usually taxable Investment Property Property held mainly for rental or investment May qualify for relief Former Home You lived there at one stage.

Now let’s see how you got the property

How did you acquire this property?

This affects how your starting value is usually approached.

I bought it You paid a purchase price It was gifted to me You received it during the previous owner’s lifetime I inherited it You received it after a death or estate transfer

For gifted or inherited property, the relevant market value at the time you received it is often important.

Land-specific check
Some land sales may involve extra tax considerations. These quick questions help us flag where a standard estimate may not tell the full story.

Development land check

Does this land have development potential?

For example, land with planning potential, zoning value, or development interest.

No Standard land sale Yes May have planning or development value Not sure I’m unsure whether this applies

Family farm / transfer check

Was this land part of a family farm transfer, gift, or inheritance?

This helps flag where agricultural or transfer-related review may also matter.

No No family farm or transfer context Yes Part of a family farm, gift, or inheritance Not sure I may need to double-check this

Complex case detected

Your land sale may need a more tailored review

Based on your answers, this looks like a case where a standard estimate may not fully reflect the final tax position.

Development potential can affect how land is treated.
Family farm, gift, or inheritance history can introduce separate review points.
You can still continue for an early guide, but this should not be relied on in isolation.

Gift and inheritance history
