As the inappropriately named Thikasabrik has stated, properties sold for up to �120,000 are exempt from what is now known as SDLT (Stamp Duty Land Tax).
A property sold for �125K would attract SDLT at a rate of 1%.
just to clarify Chris's reply - that is 1% of the total - �1,250
NOT 1% of the difference between �125 and �120.
This means that if you ar ebuying over �120k you are mimeadiatley adding on over �1000. Why not make an offer of �120k on hte house, and if they won't budge, go up to �120k for the house and �2000 for fixtures and fittings.
Also check if your purchase is in a regeneration area. Because my flat was over under 150K in a designated regeneration area (google this to find areas) I did not have to pay stamp duty.
Just in case you missed this afternoon's budget statement:
Gordon Brown today announced that the exemption for SDLT is to rise to �125k. I assume that this will apply from the start of the new tax year, next month.
