How Much Deposit Do You Need For A Buy-To-Let?

If you’re thinking of becoming a landlord, you’re likely wondering how much deposit you need for a buy-to-let. For most first-time or aspiring investors, upfront costs can be a significant concern. While the deposit requirement can feel daunting, there are also strategies available for those with limited upfront capital.

To find out more about what a buy-to-let deposit is, how much is typically required, and whether you can buy an investment property with no deposit at all, continue reading.

What is a Buy-to-Let Deposit?

A buy-to-let deposit is an upfront cash sum that you must pay when you buy a property to let out. Buy-to-let deposits are calculated as a percentage of the property purchase price, meaning they often require substantial upfront capital.

However, don’t let this put you off a potential property investment in buy-to-let — there are a few alternative methods to consider if you don’t have the cash for a deposit, such as borrowing against the equity in your current home.

Deposit Requirement for a Buy-to-Let in 2026

So, how much deposit do you need for a buy-to-let property? In 2026, most buy-to-let mortgage lenders require a minimum deposit of at least 20-25% of the property value, but this can vary depending on the lender.

Let’s take a look at a quick mortgage breakdown:

15-20% – Typically reserved for high-income borrowers
25% – The most common deposit level
30-35% – Demanded for certain types of buy‑to‑let properties
40%+ – Unlocks some of the lowest rates

People who can put down roughly 25-40% often secure better rates as they meet much tighter affordability tests.

If you don’t have a deposit, someone else might. A joint venture allows you to team up with an investor who brings the money, while you manage the property or deal.

What is Loan-to-Value (LTV) and Why Does It Matter?

Loan-to-Value (LTV) is the ratio between the amount you wish to borrow and the property’s value. The calculation is typically expressed as a percentage that shows how much of the property’s value is covered by the mortgage, rather than by your deposit.

Here’s an LTV calculation example:

You want to buy a property worth £250,000
You put down a 25% deposit (£62,500)
You borrow the rest from your lender (£187,500)

LTV = (£187,500 ÷ £250,000) × 100 = 75% LTV

Essentially, this means that you own 25% of the property outright (your deposit), and the bank owns the other 75% until you pay the full mortgage off.

What Affects How Much Deposit You'll Need?

Several key factors could potentially affect how much deposit is required for buy-to-let:

Credit History – If you have a strong credit score, you’ll potentially have access to better rates.
Rental Income – Lenders often assess whether the expected amount of rent covers the mortgage interest.
Property Type – Certain property types may require higher deposits, such as new builds or Houses in Multiple Occupation (HMOs).
First-Time Landlords – Some lenders may apply stricter criteria or ask for larger deposits if you’re a first-time landlord with minimal experience.

What Types of Deposits Do Lenders Accept?

Before your lender can approve your buy-to-let mortgage, they must ask where your deposit money has come from as a legal anti‑money‑laundering requirement under the Money Laundering, Terrorist Financing and Transfer of Funds Regulations 2017 and related rules.

Here are some acceptable sources:

Deposit Source	Meaning	Evidence
Personal savings	Money that you’ve saved up over time	3-6 months of bank statements
Gifted deposit	Money gifted to you by loved ones	A signed gift letter confirming that the money isn’t a loan and the donor has no claim on the property
Selling another property	Funds received from selling a home or investment property you previously owned	Completion statements or solicitor paperwork
Family loan	A loan taken out by a family member on your behalf	A signed letter from a family member, your bank statements, your family member’s bank statements, and a formal loan agreement
Inheritance money	Money received following a death	Probate documents or a solicitor’s letter
Equity release	Funds released by remortgaging your current home	Mortgage offer or completion statement

Please note that lenders may decline deposits from unverified or high-risk sources, so always check first.

Can You Buy an Investment Property With No Deposit?

Technically, it’s possible to buy an investment property with no deposit in some cases.

However, this isn’t typically through conventional mortgage routes, and the process requires planning and possible partnering with other investors.

Five common ways to buy an investment property with little or no deposit include:

1 – Use a Joint Venture (JV) or Investor Partner – If you don’t have a deposit, someone else might, so consider a JV that allows you to team up with an investor who brings the money while you manage the property or deal.

2 – Release Equity – A common strategy among seasoned investors is to release equity on a property you already own and use it as a deposit for a buy-to-let.

3 – Gifted Deposit or Inheritance – If you’ve recently inherited funds, they can also be used as a deposit without affecting your eligibility, as lenders often accept gifted deposits as long as they’re documented.

4 – Lease Options – A lease option gives you control of a property with the option to buy later, often without a deposit.

5 – Vendor Finance (Seller Financing) – With vendor finance, the seller agrees to be paid in instalments, meaning you gain control of the property without a traditional mortgage, often providing one upfront deposit.

So, Can You Really Buy a Property with No Deposit?

The short answer is yes, but not in the traditional way.

To buy an investment property with no money down, you’ll need to think creatively, build strong relationships, and understand the risks and rewards. If you’re new to this, check out our blog on how to start investing in property for more help.

Can using a buy-to-let calculator help?

Yes, using a buy-to-let mortgage calculator can help by providing an estimate of:

What the property you’re renting out will be worth
How much your mortgage payments will be
Whether or not the property is affordable for your initial deposit

We advise using the Barclays Bank buy-to-let mortgage calculator, which should give you a great insight into how much you can borrow for a rental property.

Can buy-to-let mortgage interest rates be fixed if you have a small deposit?

Yes, some lenders offer fixed-rate buy-to-let mortgages even if your deposit is smaller than usual, but the rates might be higher compared to larger deposits. Locking in a fixed rate can provide clarity of your monthly payments and protect you from interest rate rises.

However, lenders typically prefer larger deposits for fixed-rate deals, so it’s important to shop around and get expert advice to find the best option for your situation.
