Help to Buy Isa - first-time buyers

If you're saving for your first home, you can now open a Help to Buy Isa, which is designed to help first-time buyers get onto the property ladder.

You can deposit up to £200 a month in a Help To Buy Isa (plus an additional initial deposit of £1,000), with the government topping up these savings by 25% up to a maximum of £3,000.

Your Help To Buy Isa savings can be used to buy a home worth up to £250,000, or £450,000 in London. And if you're buying with someone else, you can open separate accounts and jointly earn a bonus of up to £6,000.

Halifax's Help To Buy Isa is the best deal announced so far, paying 4.00% AER. The next best deal - paying 1% AER less - is Virgin Money's Help to Buy Isa at 3.00% AER. 

It's worth noting that you can't contribute to a cash Isa in the same tax year as a Help to Buy Isa. Therefore, if you want to open a Help to Buy Isa in the 2015/2016 tax year, make sure you don't add any money to a cash Isa in this tax year.
