This guide will help you work out how much you're likely to be able to borrow and how much you'll need as a deposit.

Your income and the size of your deposit (or equity, if you're remortgaging) both have a fundamental impact on the amount you can borrow and what rate you'll get.

Lenders check how much you can afford

Lenders used to just multiply your income by up to five times to work out your maximum mortgage size. Now it's a lot more complicated as the lender has to check the affordability of the mortgage – but in basic terms, this just means whether you can afford the repayments.

But, again, it's still not quite that simple. Under mortgage rules which came into effect in April 2014, lenders must now obey strict guidelines to check whether a borrower can afford their mortgage repayments, not just at current interest rates, but also if interest rates shot up to 6-7%.

And, mortgage 'interviews' have got harder. They've always asked about income and big bills such as utilities & debt, but we've heard stories since the changes of gruelling three-hour interrogations where people are asked how often they eat steak. This is an extreme example, but do factor in committed spending such as gym membership, insurances, car costs, entertainment and eating out, the weekly shop as well as childcare and school fees.

Ignore the scaremongering. It's not 'they'll tell you to stop eating steak'. They're judging affordability, so if eating out costs push you over the edge it can be a problem. If you can comfortably afford it, it's not.

Even so, it's best to make it as easy for your lender as you can. Most look at your spending in the three months before you apply for a mortgage, so if you know you're about to apply, try to live sensibly, and well within your means for several months before. Put up as much as you can for the deposit if it's your first mortgage, as borrowing less means less risk for the lender, and hopefully less close scrutiny for your finances.

Can I get an accurate maximum loan figure?

Use our How Much Can I Borrow calculator to estimate how much mortgage lenders might offer you. This is a rough estimate based only on your income, so any significant outgoings, such as child maintenance, debt repayments or school fees, could reduce the amount a lender's prepared to offer you.

You won't get a fully accurate figure until you apply for a mortgage, but if you speak to a lender or a mortgage broker, they should be able to give you an estimate.

It's worth taking a look at the mortgages on offer with MoneySavingExpert's Mortgage Best Buys. From there, you'll be able to benchmark a top deal, and then either find a broker or a lender who'll be able to help you with an estimate of how much you could borrow.

You can then get an agreement in principle (AIP). An AIP is a mini-application to the lender where it asks for some personal details and carries out a credit check to see if it would be willing to lend to you, subject to further checks. It'll also tell you how much it'll lend you.

If you're approved for the AIP, the battle's half over. It means the lender's looked at you, credit checked you, and on the surface, you're someone that it would lend to. But it is only half the battle, because it's not binding on the lender, or on you.

Shall I take the max I can borrow?

If you're buying, you should find out how much you can borrow before you start house hunting, but be clear on how much you can afford.

If you're remortgaging, work out how much you need before finding out what a lender might be prepared to offer. It's easy to get tempted to up the loan size when the lender is willing, but don't exceed what you think is affordable.

Use the Budget Planner tool to work out what you can afford to repay. If it shows you can't afford a property, don't ignore it.

Only look at properties within your budget and avoid those even a fraction over. If not, you'll either break your resolve or be disappointed.

I'm self-employed. Can I still get a mortgage?

If you're self-employed or would struggle to prove your long-term income – perhaps you've worked abroad or you are on a temporary contract – then getting a mortgage is tough. You'll need cast-iron proof of your income, which isn't easy. You need to show:

  • Business accounts. You need to show preferably three years of accounts – though two can suffice depending on the lender – usually signed off by a chartered accountant.
  • Tax returns. If you can't show business accounts then two or three years' tax returns are the next best option.

You'll be assessed on net profits, not turnover. If this is likely to be complex, using a mortgage broker could help as they'll know which lenders require what evidence.

While this can work for those in established businesses, to be realistic, it could mean those who have recently started working for themselves may not be able to get a mortgage. If you're self-employed and your partner isn't, your mortgage may be calculated using their income only.

Note that self-cert mortgages – mortgages where you declare your own income and the lender doesn't require proof, common in the mid-noughties – are no longer available.

You need a 5% deposit to get a mortgage and 40% for the best rates

Once you know how much you might be able to borrow, you need to work out what you're able to provide as a deposit (or equity if you're remortgaging).

The minimum you WILL NEED is 5% but the bigger the deposit/equity, the better the rates will be (the best rates are for those with a 40%+ deposit) and the better your chances of being accepted by a lender. If you are on the borderline of affordability, having more to put down might help the lender to say yes. In short...

  • 25% – gets you a decent rate
  • 40% – gets you the top rates

So as a general rule of thumb, the more you can save up, the better, as:

"The bigger your deposit, the cheaper the mortgage deal"

What is the LTV?

On the best buy tables and comparison sites, you'll see that lenders talk about the LTV (loan to value) ratio. This is the percentage of the property value you're loaned as a mortgage – in other words, the proportion you're borrowing.

To calculate this, simply subtract your deposit/equity as a percentage of the property value from 100%. So if you've a £20,000 deposit on a £100,000 home, that's a 20% deposit. This means you owe 80% – so the LTV is 80%.

Similarly, if you're remortgaging, and you own 20% of the value of your home, you'll need a remortgage deal for the remaining 80% – this is your LTV.

Just in case you're struggling, here's an easy table…

LTV Equals deposit/equity of LTV Equals deposit/equity of
95% 5% 70% 30%
90% 10% 65% 35%
85% 15% 60% 40%
80% 20% 55% 45%
75% 25% 50% 50%

The reason it's expressed this way is so the same terms can be used for those getting a first mortgage and those who want to remortgage.

It's worth thinking about LTVs for a moment. They're not just affected by the amount you put into a house, but also by house prices. This is crucial – by owning a house, you've invested in an asset where the price moves.

A practical example: let's say when you first bought, you had a £10,000 deposit on a £100,000 house – that meant you owed £90,000 at the start. That's an LTV of 90%. After a few years you've paid a little off and now owe £85,000. You're ready to remortgage and the house's value is the same, so your LTV has become 85%.

Yet if the house is now also worth more, say £120,000, then your LTV is around 70% (as it's £85,000 divided by £120,000 multiplied by 100). This means you'll be likely to get a much better remortgage deal. Equally, if the house's value had dropped to £80,000, you'd now owe more than it's worth (negative equity) and you'd be unable to remortgage.

Pumping more of your savings into your mortgage can get you a better rate

Mortgage and remortgage rates are priced in LTV bands – and the bigger deposit/equity you have, the lower the interest rate will be. Mortgage lenders have different prices for loan-to-value bands at 60%, 70%, 75%, 80%, 85%, 90% and 95%. The impact of a lower LTV can save you a huge amount of cash (see table).

Equity 10% 20% 25% 40%
Interest rate 1.54%

1.29%

1.17% 0.89%
Loan amount £135,000 £120,000 £112,500 £90,000
Monthly cost £542 £468 £433 £335
Total payments over 2 years £13,000 £11,230 £10,400 £8,040

The table is for a house value of £150,000 on a capital repayment basis over a 25-year term and ignores fees. Updated May 2017

The relationship breaks down below 60% LTV. Someone borrowing 45% of the value of their property will typically pay the same rates as someone borrowing 60%. But if you borrow 61%, you won't be able to get those rates.

If you currently have slightly less than needed to reach one of those LTV boundaries, it's worth scraping together the extra, or – if buying – trying to haggle on the property's purchase price with the seller.

If you're at the top limit of a boundary (eg, 75% LTV), finding a little bit extra for the deposit to push you another 0.1% down (eg, to 74.9%) could improve your chances of acceptance. It could also reduce the amount of paperwork the lender wants to see.

There are two ways to drop an LTV band

1. The first one is very simple – borrow less

Work out how much additional money you would need to put in to drop to a lower interest rate band and see how much interest you'd be saving.

One way you could do this is to overpay your mortgage where you also get the advantage of paying interest on a smaller amount of debt.

And if your LTV falls, it means when it comes to remortgaging, you may be able to get a cheaper deal than if you hadn't overpaid your mortgage.

2. Get your property valued higher

When you apply for a mortgage, you need to give an estimate of the property's current value. You want to get the top value possible, but it needs to be realistic as the lender will get an independent valuer to check it later in the process.

Valuers don't just pluck a figure out of the air, and neither should you. Use our Free House Price Valuations guide to look at houses similar to yours that have sold recently, or maybe even ask a friendly estate agent for their opinion.

I've only got 5% deposit – what can I get?

If you're buying your first home, there are Help to Buy schemes which help you get on the mortgage ladder with a low deposit:

Help to Buy Equity Loan scheme

The Help to Buy (equity loan) scheme launched in April 2013. It's only for new builds and the scheme works differently depending on where you live.

In England, it's only available for those buying a new build worth less than £600,000 (£300,000 in Wales, and £230,000 in Scotland). Rather obviously, it was set up to help encourage building because of the UK's shortage of houses.

Here, provided you've a deposit of 5% and you pass the criteria, the Government will give you an interest-free (for the first five years) loan of 20% of the purchase price (40% in London, 15% in Scotland) and you raise a mortgage for the rest.

As you're only borrowing up to 80% you'll get access to cheaper rates than you would for a 95% mortgage, meaning the mortgage is much cheaper.

Yet you're not just getting a mortgage, you're getting an interest-only equity loan, which is:

  • Interest-free for five years in England & Wales.

    For the first five years the government loan is interest-free, then it's about 1.75% from year six onwards. (To be exact, it's 1.75% indexed to inflation plus 1% from year seven, so if inflation were 3% in year seven you'd pay 1.82% (3% + 1% + 100%)/100% = 1.04 x 1.75% = 1.82%). Do note, here you are only repaying the interest, not the loan itself.

  • Interest-free for life in Scotland.

    The Scottish Government won't charge interest on the loan.

  • Payable when you sell the property.

    When you sell, the Government will take 20% of the sale price – so it shares in any growth or loss. This means if house prices rise rapidly, you'll repay a lot more than you borrowed. To pay it back earlier, the market value of the property will be assessed.

There are other schemes that can help you onto the property ladder, for example, shared ownership could suit if you can't afford a 95% mortgage, but can afford one for 50%.

If you need more information on Help to Buy, shared ownership, or any of the other Government schemes, see our Mortgage Schemes guide.

If you've got a good idea of how much you can afford to borrow, you can move onto the next step. See our guide to House-hunting, or if you've already found a house, see Mortgage Schemes if you've a low deposit, or Mortgage Types.
