The budget has meant good news for First Time Buyers as properties upto £250000 are exempt from the 1% Stamp Duty
However to qualify as a first time buyer you must;
1. Not have any interest in any property either in the UK or abroad.
2. Must not have inherited any property; so even if you have not bought a house but inherited an interest in one, you do not qualify
3. If you are buying jointly with someone both of you must be first time buyers.
4. If you have previously purchased under shared ownership you do not qualify.
