As a mortgage adviser, the first conversation I have with aspiring landlords is almost always about the deposit. It’s the foundation of your investment, but figuring out the right number can feel like the biggest hurdle. I believe that with clear guidance, it doesn’t have to be.
We’ll walk through the typical deposit amounts, explore why lenders see a 25% deposit as a sweet spot, and discuss how your personal circumstances can open up different possibilities. Let’s turn that big question into a clear, achievable plan.
Key takeaways
- Expect to put down at least a 25% deposit. Most lenders cap the loan‑to‑value (LTV) at about 75%, so buyers usually need a minimum deposit of one-quarter of the property price. Deposits of 20% are occasionally available for strong cases, while 15% deals are rare and come with high rates.
- 25% Deposit: This is the standard requirement for most buy-to-let mortgages and will give you access to a competitive range of products.
- 20% Deposit: These mortgages are available but may require a stronger application, often needing proof of a high projected rental income to satisfy lenders.
- 15% Deposit: Securing a loan with this small a deposit is rare. Such deals are often difficult to qualify for and typically come with higher interest rates.
- 40% Deposit or More: By contributing a larger deposit, you reduce the lender’s risk and may be rewarded with more favourable terms and access.
- Bigger deposits unlock better rates and more choice. Lenders consider buy‑to‑let loans riskier than residential lending, so lower LTVs translate into lower interest rates. New‑builds, flats above shops and HMOs often require a 30 % or higher deposit.
- Your income and rental yield still matter. Many lenders expect borrowers to earn around £25,000 a year and to demonstrate that the expected rent covers 125% of the monthly mortgage payment.
- Work with an independent broker. A whole‑of‑market advisers at Steel City Mortgages can compare lenders, explain limited‑company options (often needing a 25–35 % deposit and help you prepare for taxes, void periods and other landlord responsibilities.

Buy-to-Let Guide: How Do Buy‑to‑Let Mortgages Work?
The basics
Buy‑to‑let mortgages are designed for investors who want to rent out a property rather than live in it. Lenders treat these loans as higher risk and set conditions that go beyond standard residential mortgages.
You’ll typically need to own your own home, have a good credit record and be earning at least about £ 25,000 a year.
Age limits are common too, with many lenders capping applications at around 75 years old.
Most buy‑to‑let mortgages are interest‑only, which means your monthly payments cover only the interest; the capital is repaid in full at the end of the term.
This structure keeps the monthly cost lower but requires you to have a plan for repaying the loan (for example through savings, sale of the property or refinancing). Repayment mortgages are available but less common and come with higher monthly payments.
Loan‑to‑Value (LTV) and Deposit Basics
The loan‑to‑value ratio tells you how much you’re borrowing compared with the value of the property. Most buy‑to‑let lenders work to a maximum LTV of 75%, which translates into a minimum deposit of 25%. Some lenders will stretch to 80% LTV for borrowers with strong credit and high rental income, but deals at 85% are almost unheard of. Lenders also calculate whether the expected rent will cover 125% (sometimes up to 145%) of the mortgage payment. Higher rental yields strengthen your case and may allow you to secure a lower deposit or better rate.
Example: Deposit Calculations
Suppose you want to purchase a terraced house in Dronfield for £200,000. A 25% deposit means you’ll need £50,000 up front. If you can raise 40% (£80000), you may access much lower interest rates and save thousands over the life of the loan.
On the other hand, if a lender is willing to accept a 20% deposit, you’d put down £40,000 but would likely pay a higher interest rate to compensate for the increased risk.
Buy-to-Let Mortgage: How Much Deposit is Needed?
Typical Deposit Ranges
Most buy‑to‑let mortgages require you to contribute between 20% and 40% of the purchase price. The standard figure is 25%. Lenders will sometimes accept a 20% deposit if you have a strong credit history, a solid income and a property that promises excellent rental yields.
15% deposits are rare and usually reserved for experienced landlords with exceptional finances.
New‑build properties or those considered higher risk (such as flats above shops or houses in multiple occupation, known as HMOs) often demand a 30–40% deposit.
Similarly, borrowers purchasing very low‑value properties (below £50 000) may find limited mortgage options.
Limited Companies vs Individual Buyers
If you decide to buy through a limited company – often known as a special‑purpose vehicle (SPV) – lenders see the arrangement as higher risk and may require a deposit of 25–35%. Limited‑company structures can offer tax advantages, especially for higher‑rate taxpayers, but they come with extra costs and stricter underwriting. Directors usually need to give a personal guarantee, and lenders will scrutinise the company’s setup and shareholders. For individual buyers, deposits tend to fall within the 20–25% range, though putting down more can improve your access to competitive rates.
Factors Influencing Your Deposit
Several variables affect the size of deposit a lender will demand:
- Property type: HMOs, holiday lets and flats over commercial premises usually carry higher risk and therefore require bigger deposits.
- Location: Areas with volatile prices or lower demand may lead lenders to ask for more equity. While Dronfield enjoys steady demand thanks to its proximity to Sheffield, investors should still budget for at least 2 %.
- Borrower profile: A strong credit score, low personal debt and reliable income make lenders more comfortable with higher LTVs. First‑time landlords and older borrowers may face stricter terms.
- Rental calculations: Lenders stress‑test your application against potential interest‑rate rises. A high rental yield can compensate for a smaller deposit, whereas a borderline yield may push you towards a larger one.
- Market conditions: During periods of economic uncertainty or rising interest rates, lenders tighten criteria, often requiring bigger deposits to mitigate risk.
Property Buy to Let: Eligibility and Planning
1. Income, age and rental yield
When assessing buy‑to‑let borrowers, lenders look beyond the deposit.
- Many require you to be earning around £25 000 or more, excluding rental income, so they know you can cover payments during void periods.
- They’ll also consider your age – most lenders won’t lend to someone who will be older than about 75 at the end of the mortgage term. To stress‑test affordability, lenders ensure the anticipated rent is at least 125% of your monthly mortgage payment.
- For example, if your interest‑only payment is £800 per month, you’d need to demonstrate projected rent of at least £1 000.
2. Additional costs and responsibilities
Your deposit isn’t the only cash you’ll need. As a landlord you must account for stamp duty surcharges, valuation and arrangement fees, legal costs and ongoing maintenance. It’s also wise to keep a buffer for unexpected repairs and periods when the property is empty. You’ll be responsible for income tax on rental profits and capital gains tax when you sell. Keeping accurate records of letting‑agent fees, maintenance expenses and council tax during vacancies can reduce your tax bill.
3. Acceptable sources of deposit
Lenders want to see where your deposit comes from. Acceptable sources include personal savings, equity released from your own home, proceeds from the sale of another property or a gift from family. Gifted deposits usually require a formal letter confirming the money is a gift, not a loan. Unsecured borrowing (such as credit cards or personal loans) and unexplained overseas transfers are generally not accepted.
4. Accidental landlords and remortgaging
If you inherited a house in Dronfield or moved in with a partner and decided to let your old home, you become an “accidental landlord”. In that case you must inform your lender; renting out a property on a standard residential mortgage could breach the terms of the loan. Some lenders will grant consent to let, while others insist on switching to a buy‑to‑let mortgage. If your current lender refuses, remortgaging with a specialist lender could be an option, although it may trigger early‑repayment charges. Here’s where a broker can analyse costs and guide you through the process.
Buying to Let: Saving for Your Deposit and Next Steps
Practical saving strategies
Building a 25% deposit can seem daunting, but breaking it down into achievable steps helps. Here are some practical tips:
- Set a monthly savings goal. Work backwards from your target deposit and timeline. Automate transfers into a dedicated savings account so you’re less tempted to spend the money.
- Cut unnecessary expenses. Review subscriptions, insurance and discretionary spending. Even small cuts add up over time.
- Explore government savings schemes. Certain ISAs offer tax‑free returns and bonuses for property purchases (for example, Lifetime ISA), although some schemes are aimed at first‑time residential buyers rather than buy‑to‑let investors.
- Release equity or re‑mortgage your own home. Releasing equity from your main residence or another investment property can accelerate deposit building.
- Aim for high rental income. Selecting a property with strong rental potential can persuade lenders to accept a smaller deposit or offer better rates. Properties near commuter lines to Sheffield or Chesterfield often attract reliable tenants.
- Work with a broker. An adviser can identify lenders offering low‑deposit deals and help you present your application in the best light.
Beyond the Deposit: Planning for the Long Run
After you’ve saved your deposit and secured a mortgage, your role as a landlord includes budgeting for void periods, repairs and compliance. Keep a reserve fund so you can cover unexpected costs like boiler replacements or roof repairs. Ensure you have suitable landlord insurance and consider income‑protection cover so you’re not caught off guard. And remember that interest‑only mortgages don’t reduce your principal; plan how you’ll repay the capital at the end of the term.
Frequently Asked Questions About Buy‑to‑Let Deposits
Can I use a 10 % deposit?
No. Buy‑to‑let mortgages typically start at 20% deposits. Ten‑percent deposits are generally only available on residential mortgages backed by government schemes.
Is a 20% buy‑to‑let deposit realistic for first‑time landlords?
It can be, but expect stricter affordability checks and higher interest rates. Lenders may ask for proof of higher rental income and excellent credit. Many first‑time landlords in Dronfield opt for a 25 % deposit to secure better deals.
How do deposits work when buying through a limited company?
Limited‑company buy‑to‑let mortgages often require deposits of 25–35%. Directors must usually give personal guarantees. While this structure can deliver tax benefits, it isn’t suitable for everyone; seek professional tax advice.
Do lenders accept gifted deposits?
Yes, provided the donor confirms the funds are a gift and not a loan. The donor may need to sign a declaration. Lenders will still check your affordability and the property’s rental potential.
Strength in Your Mortgage Journey
Understanding how much deposit you need for a buy‑to‑let is the first step in building a successful rental portfolio in Dronfield. In most cases you should budget for around 25 % of the purchase price, though some borrowers manage with 20% and experienced investors sometimes choose to put down more to access lower rates.
Deposit requirements vary with property type, borrower profile and market conditions, so there’s no one‑size‑fits‑all answer. A tailored approach – assessing your income, rental yield, long‑term goals and tax situation – will help you decide how much to save and how to structure your investment.
