Buying your first home is one of the most exciting things you'll ever do — but it
can also feel pretty overwhelming. Between deposits, mortgages, LTVs and
Stamp Duty, there's a lot to get your head around. We've put this guide together
to walk you through the essentials, so you can approach the process with
confidence.

What is a Mortgage, and How Much Deposit Do I Need?
Most people who buy a home don't have the full purchase price sitting in their bank account
that's completely normal. A mortgage is simply a loan from a lender that allows you to buy a
property, which you then repay monthly over an agreed period, with interest. While the
traditional mortgage term used to be 25 years, the average first-time buyer mortgage is now 31 years.
To secure the property, you'll need to put down a deposit upfront — a percentage of the
purchase price paid from your own savings. In most cases, you'll need at least 5%. So on a
£250,000 home, that's a minimum of £12,500.
💡 Good to know: The larger your deposit, the less you'll need to borrow — and the
better the mortgage rates you're likely to be offered. A bigger deposit = more choice
and lower monthly repayments.
There are also options like 100% mortgages (no deposit required) and guarantor mortgages forthose who may struggle to afford repayments alone, though each comes with its own
advantages and drawbacks.

Loan to Value (LTV) — and Why It Matters
Loan to value, or LTV, is simply the ratio of your mortgage to the property's total price. If you putdown a 5% deposit of £12,500 on a £250,000 home, you'd be borrowing £237,500 — giving youan LTV of 95%.
95%LTV on a 5% deposit (£250k home)
80%LTV on a 20% deposit — better rates, lower risk

Buying Your First Home:
What You Need to Know
By Birtles Mortgage & Financial Solutions
The lower your LTV, the less of a risk you appear to a mortgage lender. That's because you havea smaller loan relative to the property's value, making it less likely you'd ever owe more than the home is worth. Lenders reward this with more competitive rates — another reason a larger deposit can pay off in the long run.

Stamp Duty and the Other Costs You Shouldn't Overlook
Your deposit and monthly mortgage repayments are the big ones — but buying a home comeswith a few other costs that are easy to overlook if you're not prepared for them.
Stamp Duty Land Tax (SDLT) is a tax paid on properties in England and Northern Ireland above acertain price threshold.
The good news for first-time buyers is that you're currently exempt fromStamp Duty on homes up to £300,000. (In Scotland, the equivalent is Land and Buildings
Transaction Tax; in Wales, it's Land Transaction Tax.)
Beyond Stamp Duty, here are the other one-off costs to factor into your budget:
🔍 A home survey to assess the property's condition
⚖️ Conveyancer or solicitor fees to handle the legal side
🏠 Buildings insurance (usually required by your lender)
🚚 Moving costs — removal vans, new furniture and the rest
💡 It's worth building a buffer into your savings for these extras. Being caught short at
the end of the process is stressful — and avoidable with a little planning.
