Buying another property

Work out the deposit for your next property

Will you sell your current home, keep it to live in, or let it out? That decision changes where the deposit may come from, which mortgage route to check and what cash you may need at completion. Count Ready can help you put the funding plan together before you commit.

Begin with the purpose

How much deposit do you need for another property?

There is no deposit percentage that applies to every second purchase. The lender will look at the new property's use, its value and type, the borrowing requested, the source of your contribution and whether the repayments are affordable alongside commitments you already have.

A home you will move into, a second home for personal use and a property you intend to let can lead to different mortgage assessments. If you are selling your current main home, your usable sale proceeds may contribute to the new price. If you keep it, the equity shown by a valuation is not automatically cash you can put down.

What does “second mortgage” mean? It can mean a mortgage on another property, or a second-charge loan secured on the home you already own. This page deals with the deposit for buying another property. For borrowing secured behind an existing mortgage, see our second-charge mortgage page.
Choose the right funding question

Are you selling, keeping or letting your current home?

Selling and moving

Start with the expected sale price, the mortgage balance, selling costs and any early repayment charge. Your conveyancer can estimate the net money and confirm when it can be used in the purchase. Ask how the sale and purchase dates fit together.

Keeping it for your own use

You may need to show that you can afford both homes and all related costs. Tell the lender how each property will be used. A separate second-home mortgage assessment may be needed for the new purchase.

Keeping it and letting it

Do not assume your current residential mortgage allows tenants. Discuss the lender's consent or a possible change to let-to-buy finance, and how the existing loan and any rental assessment affect the new application.

If guests will stay for short periods, see the separate holiday-let mortgage page. A lender must be told the real intended use; one product label does not give permission for every use.

From value to usable funds

Can you use equity in your current home for the deposit?

Possibly, but first separate paper equity from money that will actually be available. The difference between an estimated property value and outstanding mortgage is only a starting figure. A sale, further advance, remortgage or second-charge loan can each have different costs, approval requirements and risks.

Difference on paper£120,000
Deposit cash ready to useNot known

The £120,000 is simple arithmetic, not an amount a lender has agreed to release. If you sell, repayment, legal and selling costs, charges and the actual sale price affect the net proceeds. If you keep the home, new borrowing would require a lender assessment and would add repayments. Do not base an offer on this estimate alone.

Ask your existing lender about the mortgage balance and any early repayment charge. An adviser can help compare the cost and suitability of possible borrowing routes; your conveyancer can confirm what funds arrive and when. Our remortgage advice page covers the wider refinance decision.

Cash beyond the deposit

What else belongs in the purchase budget?

Deposit source and timing

List savings, sale proceeds, a genuine gift or any proposed borrowing separately. A lender and conveyancer can require evidence of where the funds came from. If the sale of your current home must complete first, tell your conveyancer before you rely on that money for an earlier contract payment.

Two-home costs

Allow for existing and proposed mortgage repayments where both homes will be kept, plus insurance, maintenance, council tax or running costs. Include legal fees, survey, moving costs and a reserve rather than putting every available pound into the deposit.

Property transaction tax

Buying an additional home can trigger higher tax rates, while replacing a main residence may be treated differently. Rules depend on ownership, dates, location and the other buyers. Ask your conveyancer to check the actual liability before you set the cash budget.

England and Northern Ireland use Stamp Duty Land Tax, Wales uses Land Transaction Tax, and Scotland uses Land and Buildings Transaction Tax with an Additional Dwelling Supplement where applicable. The rules and rates can change. Our SDLT calculator is only a starting estimate for England and Northern Ireland; it does not calculate the Welsh or Scottish taxes.

How Count Ready helps

Turn two properties into one clear mortgage plan

01

Tell us the purpose

Which home will you live in? Will the other be sold, kept for personal use or let? Give the location and approximate price of the proposed purchase.

02

Outline the existing home

Share an estimated value, mortgage balance, current payment, any known charge and the sale or letting timetable. Rough figures are enough to start.

03

Check the cash and borrowing

We can discuss the proposed deposit source, affordability, property use and current lender criteria. Your conveyancer confirms legal and tax figures.

04

Prepare the next step

If a route appears worth exploring, we explain the evidence and application steps. The lender makes the lending decision after its own checks.

The first conversation does not require statements, identity documents or account numbers through an open message. Read about Count Ready and the Terms of Business linked in the footer before proceeding; any applicable fee should be agreed before chargeable work.

Discuss the funding plan

Check the funding plan before you make an offer

Tell us whether you will sell or keep the current home, who will use the new property, the approximate price, deposit and source, and your timescale. We can identify the mortgage questions to check without promising a product or approval.

Short answers

Deposit questions when buying another property

Is a second mortgage the same as a second-home mortgage?

No. “Second mortgage” can mean a second-charge loan secured on a property you already own. A second-home mortgage funds another property. Tell an adviser whether you want to raise money against your current home or borrow to buy an additional one.

Will I always need a larger deposit for a second property?

No single percentage applies. The lender's current product, the property, its intended use, your existing borrowing and affordability determine what contribution is needed. Do not assume a deposit quoted for one purpose will work for another.

Can I use equity in my present home?

Potentially, through sale proceeds or approved new borrowing. Estimated equity is not automatically available cash. A sale has repayment and transaction costs; borrowing against a home adds debt and depends on lender checks.

What if I keep my present home and rent it out?

Tell your existing lender before letting it. You may need consent or a suitable let-to-buy arrangement, while the new home needs its own mortgage assessment. Rental expectations, existing payments and property tax all require checking.

Will I pay extra property tax?

Possibly. Higher rates can apply when you buy an additional dwelling, while a replacement main residence may be treated differently. Rules vary between England and Northern Ireland, Wales and Scotland. Ask your conveyancer to calculate the amount for your ownership and completion dates.

Can I buy before my current home sells?

It may be possible, but the money needed and risks change if sale proceeds are not yet available. Discuss the purchase timetable, any interim borrowing, existing repayments and possible higher property tax with your adviser and conveyancer before committing.
