How to finance property development

The most common way to finance property development is a development finance loan that releases funds in stages as your build progresses, though bridging finance, commercial mortgages, joint venture equity and mezzanine finance can all play a part depending on your project and how you plan to exit. Which combination works best for you comes down to how much of the cost you can fund yourself, how quickly you need the money and what you plan to do with the finished units once the build is complete.

Property development is expensive to get wrong, so it pays to understand every route open to you before you commit to a site. This guide walks through each option, how much you can typically borrow, what it costs and how to put together a strong application, drawing on Capitalise's panel of 130+ UK lenders.

What are your options for financing a property development?

Most developers use more than one type of finance across a single project, rather than relying on one loan from start to finish. The right mix depends on your project's stage, size and your own financial contribution.

Development finance is the backbone of most schemes, but combining it with mezzanine finance or a joint venture partner is common when your own contribution does not stretch far enough to reach a lender's loan to cost limit.

How does property development finance work?

Property development finance releases your loan in stages, known as tranches, as your build reaches agreed milestones such as foundations, superstructure, roofing and fit out, rather than paying out the full amount on day one. A monitoring surveyor typically checks progress before each stage releases, which protects both you and the lender if the build runs into problems.

Interest is charged only on the funds you have actually drawn down, so a well staged build often costs less in practice than a simple loan calculation suggests. Most facilities run for 12 to 24 months on an interest only basis, with the balance cleared once you sell the finished units or refinance onto a longer term option such as a commercial mortgage. You can test how different loan amounts, terms and rates would affect your own monthly and total cost using our development finance calculator before you approach a lender.

How much can you borrow for a property development?

Lenders set your maximum loan using two separate measures, loan to cost and loan to gross development value, and whichever limit you hit first sets your actual borrowing cap.

A strong scheme with a realistic gross development value, a sensible land price and a solid contribution from you will unlock funding closer to the top of these ranges. Putting more of your own money into the project, rather than borrowing right up to a lender's limit, also tends to earn sharper pricing.

What does it cost to finance a property development?

Development finance is priced monthly rather than annually, and moves with your loan to cost, your loan to gross development value, your experience and how strong your exit plan is. As a general guide, rates across the Capitalise panel currently sit between around 0.75% and 1.5% a month, which works out at roughly 9% to 18% a year once annualised. The Bank of England base rate has sat at 3.75% through mid 2026, though base rate movements matter less to your final price than the strength of your scheme itself.

A few factors move your rate up or down more than anything else:

• Your experience as a developer and track record of finishing projects on time and on budget

• The type and location of your development, and how much local demand there is for the finished units

• How much of the project cost you contribute yourself, in cash or existing land equity

• How much headroom you keep below a lender's loan to cost and loan to gross development value limits

• How clear and well evidenced your exit strategy is, whether that is a sale or a refinance

• Your personal and business credit history

Beyond the headline rate, budget for an arrangement fee of around 1% to 2% of the loan, a valuation fee, monitoring surveyor fees charged at each drawdown, legal fees and an exit fee due when the facility is repaid.

Using joint ventures and mezzanine finance for bigger schemes

For large or ambitious schemes, development finance on its own might not cover the whole cost, which is where equity and mezzanine finance come in.

• Joint venture equity involves a partner contributing cash, land or both in exchange for a share of the finished profit rather than fixed repayments. It suits developers with the skills and time to run a project but not the full capital to fund their own contribution.

• Mezzanine finance sits behind your senior development loan as a second charge, filling the gap between what the senior lender allows and what you can put in yourself. It is priced higher than senior debt to reflect the extra risk, but it lets you take on a larger scheme with a smaller personal deposit.

Both routes reduce how much cash you need upfront, though they also reduce your share of the eventual profit, so it is worth weighing the cost of the finance against how much of the upside you are willing to give away.

Am I eligible to finance a property development?

Lenders assess the strength of your scheme alongside your background as a developer, rather than relying only on your personal or business finances. To be eligible, you will generally need:

• A viable scheme with a realistic build cost, gross development value and profit margin

• Some equity or cash contribution towards the land and build costs

• Evidence of your experience, or a strong professional team if you are newer to developing

• A clear exit strategy, such as selling the finished units or refinancing onto a commercial mortgage

• Planning permission already in place, or a credible route to securing it

First time developers are not automatically ruled out. Working alongside an experienced project manager, contractor or joint venture partner can bring lenders on our panel into play even without a personal track record.

How to apply for property development finance, step by step

1. Cost out your scheme. Work out your land cost, build cost, professional fees and expected gross development value, then run the numbers through our development finance calculator to see an estimate of your monthly and total cost.

2. Gather your documents. Pull together your appraisal, planning status, developer CV and financial paperwork so your application is complete from the outset.

3. Apply and compare the panel. Submit one application to Capitalise and we match your scheme against lenders from our panel of 130+ most likely to offer competitive terms.

4. Draw down and build. Once you accept an offer, funds release in stages as your build hits agreed milestones, with a dedicated funding specialist supporting you through to completion.

How to get a better rate when financing your development

A handful of practical steps can move your quote into a cheaper rate band before you approach a lender at all.

• Put in more of your own equity or cash towards land and build costs to lower your loan to cost ratio

• Get your exit evidenced with a pre agreed refinance, comparable sales or a realistic, demand backed sales strategy

• Build your track record gradually, since completed projects delivered on time and on budget are one of the biggest factors in future pricing

• Keep headroom against a lender's maximum loan to cost or loan to gross development value rather than borrowing right up to the ceiling

• Compare more than one lender, since appetite and pricing for the same scheme can vary significantly across specialist lenders

Common mistakes to avoid when financing a property development

A few habits consistently cost developers more than they need to pay.

• Focusing on the headline monthly rate without factoring in arrangement, valuation, legal and exit fees

• Applying to one lender rather than comparing appetite and pricing across a panel

• Underestimating the build programme, which changes both your total interest cost and your rate risk

• Approaching lenders with only a partial planning application rather than full permission

• Overstretching on loan to cost or loan to gross development value, leaving no room to negotiate a better rate

• Assuming a lack of prior experience rules out finance entirely, when a strong professional team can often unlock the same lenders
