If you are a first-time buyer in Sleaford or the wider Lincolnshire area, one of the biggest questions is usually quite simple:
What do you need to earn for the type of property you are looking at?
This often comes up when browsing local new build developments and trying to work out whether the numbers realistically stack up.
A good local example is Bellway’s Quarrington Edge at Handley Chase, just outside Sleaford, where current asking prices include:
- 3-bedroom homes from £229,950
- 4-bedroom homes from £309,950
- larger 4-bedroom homes up to £379,950

For the purpose of this guide, let’s use a £300,000 purchase price, as this is a realistic local example for many first-time buyers considering a new build family home.
What salary is typically needed for a £300,000 mortgage?
Most lenders will usually look at borrowing around 4 to 4.5 times household income.
Using that as a guide, a £300,000 mortgage would often require an income somewhere in the following range:
- £75,000 at 4x income
- £67,000 at 4.5x income
However, this is not always the full picture.
Depending on your overall circumstances, some lenders may be prepared to go further. In some cases, borrowing up to 6 times income can be possible, particularly for applicants with strong credit, stable employment and low existing commitments.
That means the same £300,000 borrowing could potentially work with:
- £50,000 income at 6x
- £60,000 income at 5x
- two salaries of £30,000
- two salaries of £25,000 where a higher multiplier is available
This is often where first-time buyers start to realise that a joint application can make the numbers feel much more achievable.
That said, the goal should never be to borrow the absolute maximum simply because it is available.
The right figure is the one that still allows you to live comfortably.
What deposit do you need on a £300,000 house?
Many first-time buyers start with a 5% deposit, so let’s start there.
On a £300,000 property, that would be:
- £15,000 deposit
- £285,000 mortgage
If you were working on a more typical 4.5x income multiple, that would generally require a combined income of around £63,000.
A 10% deposit gives you a stronger position:
- £30,000 deposit
- £270,000 mortgage
At 4.5x income, this would mean an income of around £60,000.
At 6x, it could be closer to £45,000.
This is why saving a larger deposit can make such a difference, not only in terms of lender options, but also the level of income required.
The buying costs many first-time buyers forget
The deposit is only part of the total cash needed.
There are usually several other upfront costs that need to be factored in before you collect the keys.
Typical examples on a £300,000 purchase might include:
- Solicitor and conveyancing fees: £1,200 to £1,800
- Survey and valuation: £300 to £700
- Mortgage product fee: £0 to £999+
- Removal costs: £300 to £800
- Initial furnishing and white goods: £1,500 to £5,000+
So, while a 5% deposit may be £15,000, a more realistic cash target is often somewhere closer to £18,000 to £22,000 or more.
This is one of the most common areas where buyers underestimate the true cost of moving.
You still need room every month
This is the part we always encourage buyers to think carefully about.
Just because a lender says yes does not automatically mean it is the right number for your lifestyle.
For example, monthly mortgage payments on a £300,000 purchase could be in the region of £1,350 to £1,500 per month, depending on the rate, deposit and mortgage term.
But life does not stop there.
You still need room for:
- groceries: £300 to £500 per month
- fuel and travel: £150 to £300
- utilities and broadband: £200 to £300
- council tax: £150 to £220
- home insurance: £30 to £60
- everyday life, emergencies and some breathing space
This is why we always help buyers work backwards from what feels comfortable, rather than simply chasing the maximum borrowing figure.
See what this could look like for you
The examples above are a helpful guide, but every first-time buyer situation is different.
Your borrowing potential will also depend on things like:
- your deposit
- any loans or car finance
- whether you are buying on your own or jointly
- the length of mortgage term
- your monthly comfort level
To help make the numbers feel more real, we recommend trying our first-time buyer mortgage calculators.
A good place to start is our Mortgage Affordability Calculator, which helps you estimate what you may be able to borrow based on your income and deposit.
