How much money do you need to buy your first rental property?

To buy your first rental property with a buy-to-let mortgage, you usually need much more than the deposit. Many lenders ask for a deposit of at least 25% of the price, and on top of that you pay stamp duty (or its Scottish or Welsh equivalent), legal, survey and lender fees, the cost of getting the property ready to let, and a cash reserve for empty months and repairs. In the illustrative example below, a £180,000 property in England needs a £45,000 deposit but about £66,800 of cash in total. Your own figure depends mainly on the price, the deposit your lender requires, and whether you already own a home.

Deposit versus total cash required

It helps to split your budget into three parts:

  1. The deposit. The share of the price you pay yourself. The lender funds the rest.
  2. Purchase and setup costs. Tax, fees and anything you must spend before a tenant moves in. This money does not reduce your mortgage.
  3. Reserves. Cash you keep back after completion so a void, an arrears problem or a broken boiler does not become a crisis.

Most "how much deposit" answers only cover part 1. You have to fund parts 1 and 2 at or soon after completion, before any rent arrives, and part 3 is what keeps the investment steady afterwards.

The deposit: what lenders usually ask for

Buy-to-let deposits are normally larger than for a home you live in. Barclays says buy-to-let deposits are "typically at least 25%", and HSBC's published criteria cap buy-to-let borrowing at 75% loan-to-value. Some lenders offer higher loan-to-value products and some ask for more than 25%. Lender criteria change often, so treat 25% as a common starting point, not a rule.

Lenders also set conditions on the property and on you. For example, HSBC's published criteria include a minimum property value and a minimum personal income outside the rent. Other lenders use different thresholds.

Why the rent can push your deposit up

Buy-to-let lending is mainly assessed on the rent, not just your salary. Lenders check that the expected rent covers the mortgage interest by a set margin, calculated at a "stressed" interest rate that is higher than the rate you will actually pay. This is often called the interest cover ratio or rental cover test. The Bank of England's Prudential Regulation Authority sets minimum underwriting standards for this in supervisory statement SS13/16, and each lender sets its own ratio and stress rate on top.

As one published example, HSBC requires annual rent of at least 125% of a stressed interest-only payment if all applicants are basic-rate taxpayers, or 145% if any applicant is a higher-rate taxpayer.

The practical point for your budget: if the rent is low relative to the price, the lender may only lend a smaller amount. You then need a bigger deposit than 25%, which increases the cash you need. The example below shows how this works.

Purchase costs

Stamp duty in England and Northern Ireland

Stamp Duty Land Tax (SDLT) applies in England and Northern Ireland. The rates GOV.UK publishes today for a single residential property are:

Portion of the priceStandard rateHigher rates for additional dwellings
Up to £125,0000%5%
£125,001 to £250,0002%7%
£250,001 to £925,0005%10%
£925,001 to £1.5 million10%15%
Above £1.5 million12%17%

Which column applies to you depends on your circumstances:

  • You already own a home (or part of one) worth £40,000 or more, anywhere in the world, and are keeping it: you normally pay the higher rates. Married couples and civil partners are treated as one unit, and if any joint buyer would pay the higher rates, the whole purchase does.
  • The rental will be the only residential property you own: you normally pay the standard rates.
  • You will not live in it: first-time buyers' relief does not apply. HMRC's guidance says the relief is for buyers who intend to occupy the property as their only or main residence.
  • You are buying through a limited company: companies normally pay the higher rates on residential property worth £40,000 or more. See our guide to buying through a limited company.
  • You are not UK resident (broadly, not present in the UK for at least 183 days in the 12 months before buying): a 2% surcharge applies on top of all other residential rates, including the higher rates.

SDLT must be reported and paid within 14 days of completion, and your conveyancer usually handles this. Check your own figure with HMRC's SDLT calculator.

Scotland and Wales

Different taxes apply, run by different authorities:

  • Scotland: Land and Buildings Transaction Tax (LBTT), administered by Revenue Scotland. Residential LBTT starts at 0% up to £145,000. If you already own a residential property and are not replacing your main home, the Additional Dwelling Supplement (ADS) normally applies at 8% of the whole purchase price (for transactions from 5 December 2024, on properties of £40,000 or more). Companies normally pay ADS even if they own no other dwelling.
  • Wales: Land Transaction Tax (LTT), administered by the Welsh Revenue Authority. Main residential rates start at 0% up to £225,000. Higher residential rates, which apply if you already own a residential property and to companies, start at 5% on the first £180,000 (from 11 December 2024).

Use Revenue Scotland's calculator or the Welsh Government's LTT calculator for your own figure.

Legal, survey and lender fees

Expect to pay for conveyancing and searches, a survey, and the lender's valuation. Many lenders also charge a product or arrangement fee, and a mortgage broker may charge a fee. These vary widely, so get written quotes before you commit.

Getting the property ready to let

Even a property in good condition may need cleaning, minor repairs, some furniture or white goods, and the safety checks and certificates required where the property is located. Budget for these before the first rent arrives.

Reserves: the part most budgets leave out

Your first month's rent may not arrive until a few weeks after completion, and repairs do not wait for a convenient time. A reserve held in cash, separate from your personal savings, covers:

  • mortgage payments and running costs during an empty period (a void)
  • unexpected repairs and replacements
  • a rise in your mortgage payment when a fixed rate ends

There is no official reserve figure. Base yours on your actual monthly mortgage and running costs, and the age and condition of the property.

Illustrative example: total cash for a £180,000 first rental in England

This is a fictional example to show the method. It is not a real property, a forecast or a typical result.

Assumptions

  • Location: England. Purchase price: £180,000.
  • Buyer is an individual, UK resident, who already owns the home they live in, so the SDLT higher rates apply.
  • Deposit: 25% (£45,000). Mortgage: £135,000 (75% loan-to-value), interest-only.
  • Legal fees and searches £1,800; survey £600; lender valuation £300; lender product fee £1,000 paid upfront; broker fee £500. All assumed for illustration.
  • Setup before letting (cleaning, minor repairs, basic furnishing, safety checks): £2,500, assumed.
  • Cash reserve: £5,000, assumed.
  • Expected rent: £950 a month, assumed.
ItemAmount
Deposit (25%)£45,000
SDLT at the higher rates (5% of £125,000 plus 7% of £55,000)£10,100
Legal fees and searches£1,800
Survey£600
Lender valuation£300
Lender product fee£1,000
Broker fee£500
Setup before letting£2,500
Cash reserve£5,000
Total cash needed£66,800

In this example, the total cash is about 37% of the purchase price, against a 25% deposit.

If the rental would be the buyer's only residential property, SDLT at standard rates would be £1,100 (2% of £55,000) instead of £10,100, and the total would fall to £57,800.

If the lender's rental cover test is tighter. Suppose, purely for illustration, a lender required annual rent of 145% of interest at a stressed rate of 7%. The most it would lend is £11,400 of annual rent ÷ (1.45 × 7%), which is about £112,300. The deposit would rise to about £67,700 (around 38% of the price), and the total cash needed to about £89,500. At an illustrative 125% cover and 5.5% stress rate, the rent would support more than £135,000, so the 75% loan-to-value cap would be the limit instead. The ratio and rate here are assumptions, not any lender's current terms.

Tax on the same £180,000 purchase in each nation (rates checked 20 October 2026; individual buyer):

WhereOwns no other residential propertyAlready owns a home
England or Northern Ireland (SDLT)£1,100£10,100
Scotland (LBTT, plus 8% ADS if applicable)£700£15,100
Wales (LTT main or higher rates)£0£9,000

A non-UK resident buying in England or Northern Ireland would add 2% of the price (£3,600) to either SDLT figure.

Your starting budget checklist

  • [ ] Price range you are realistically looking at
  • [ ] Deposit your target lender requires, and whether the rent passes its rental cover test at that loan size
  • [ ] Your stamp duty position: own a home or not, buying personally or through a company, UK resident or not, and which nation
  • [ ] Written quotes for legal fees, survey and broker
  • [ ] Lender fees, and whether you will pay them upfront or add them to the loan
  • [ ] Setup costs before the first tenant
  • [ ] A cash reserve based on your own monthly figures
  • [ ] Money you are keeping back for your own household, which should not be counted in any of the above

Once you know your total cash figure, the next question is whether the property pays its way each month. Our guide on how to calculate rental cash flow covers that.

Common questions

Can I use first-time buyer relief on a buy-to-let?

No, not in England and Northern Ireland. HMRC's guidance says first-time buyers' relief applies where the buyer intends to occupy the property as their only or main residence. A property you buy to let out does not meet that condition, even if it is the first property you have ever bought.

If I do not own a home, do I still pay the higher rates of stamp duty?

In England and Northern Ireland, the higher rates apply when the purchase means you will own more than one residential property worth £40,000 or more. If the rental will be your only residential property, you would normally pay the standard rates instead. Married couples and civil partners are treated together, joint purchases pay the higher rates if any buyer would, and companies normally pay the higher rates regardless. Scotland (ADS) and Wales (LTT higher rates) have their own versions of these rules.

Can I add the mortgage fee to the loan to reduce the cash I need?

Some lenders allow a product fee to be added to the loan. That lowers the cash you need on day one, but you then pay interest on the fee for the life of the mortgage, and it slightly increases your loan-to-value. Ask your lender or broker to show both options side by side.

How big should my cash reserve be?

There is no official figure. A practical starting point is enough to cover several months of mortgage payments and running costs with no rent coming in, plus a repair allowance that reflects the age and condition of the property. Keep it separate from your personal emergency fund.
