Development finance is a short-term funding facility that releases capital in stages as a construction or renovation project progresses. For property developers, it covers land acquisition, build costs, and professional fees, with drawdowns aligned to each phase of work. At £500,000, this funding level suits small-to-medium residential schemes, light commercial conversions, or multi-unit refurbishments where staged cashflow is essential to keeping the project on schedule.
Comparing development finance lenders goes well beyond the headline interest rate. Developers should weigh loan-to-cost ratios, the lender's experience with similar project types, and the flexibility of staged drawdowns. Facility terms, exit fees, and whether interest is rolled up or serviced monthly can significantly affect project viability. At £500,000, some lenders also require a proven track record, so first-time developers should check experience requirements before applying.
Important note:
Funding Agent
Published loan rangeFrom £10,000 to up to £1,000,000
Rate typeInterest from 6.8% annually
Why it is included:It is included because many business owners need to compare several finance routes before choosing where to apply.
Funding Agent can help businesses compare suitable options across a lender panel, especially when eligibility depends on turnover, sector, trading history, credit strength and available documents.
Best use case: When the borrower wants to avoid applying to one lender at a time.

Why it stands out
- Useful when a business wants to compare lender fit rather than guess which lender to apply to first.
- Can help position the application around the funding purpose, trading profile and available documents.
- Works well as a conversion route for readers who are unsure whether a direct lender will approve a larger unsecured facility.
Need to know
- Funding Agent is a broker, not a lender.
- The lender, not Funding Agent, sets the final rate, term, fees and approval decision.
- The best match may be unsecured, secured, revolving credit, invoice finance or another product depending on the case.
Expert take
Funding Agent is a useful honourable mention for business owners who want to compare lender options before submitting a full application. A larger unsecured loan is not always approved by the first lender a business finds, so understanding lender fit early can reduce wasted time and avoid unnecessary declines.

How development finance works for £500,000 construction and renovation projects
Development finance at the £500,000 level funds the building or heavy refurbishment of residential and commercial property. Unlike a term loan paid out in one lump sum, development facilities release funds in stages tied to construction milestones such as groundworks, wall plate, and roof completion.
Lenders typically advance an agreed percentage of land and build costs at each stage. A quantity surveyor or monitoring surveyor usually inspects the site before each drawdown. This keeps the lender aligned with progress and helps developers manage cash flow between stage completions.
For a £500,000 project, the developer usually funds initial groundwork from their own capital first. The first drawdown then reimburses those costs once verified, with subsequent releases following each certified stage. Interest is charged only on drawn funds, not the full facility, which keeps holding costs manageable during the build phase.
Loan-to-cost ratios and exit strategies for £500,000 development finance
Development lenders assess risk through loan-to-cost (LTC) and loan-to-GDV ratios. LTC measures the loan against total project cost, while loan-to-GDV compares it against the completed scheme's market value. At £500,000, most lenders cap lending between 65% and 75% of GDV or cost, whichever is lower.
From the lenders reviewed, One Stop Business Finance and Inhale Capital both publish a maximum 75% LTV, while MT Finance caps at 70%. Brightstar is an outlier, publishing up to 100% LTV for qualifying cases. United Trust Bank also caps at 75% LTV, typical for institutional development lenders.
Exit strategy matters as much as entry. Development finance is short-term, so lenders want a clear route to repayment. Common exits include selling the completed units, refinancing onto a commercial mortgage or buy-to-let facility, or using retained profits from the sale of part of a multi-unit scheme. A well-prepared exit plan strengthens any £500,000 development finance application.
What property developers pay in interest on £500,000 development facilities
Development finance interest is typically charged monthly on drawn funds only. At the £500,000 level, rates vary meaningfully between specialist and institutional lenders.
| Lender | Typical Rate Range |
|---|---|
| MT Finance | 0.89% to 1.05% per month |
| Inhale Capital | 1.05% to 1.3% per month |
| One Stop Business Finance | 1.6% to 3% per month |
| Brightstar | 5% to 12% per year |
| United Trust Bank | 5% to 12.5% per year |
Shire Leasing and Shireassetfinance sit in the 4% to 12% per month range, reflecting their shorter-term, higher-risk positioning. Arrangement fees, typically 1% to 2% of the facility, and legal and monitoring surveyor costs also apply. Developers should compare the all-in cost rather than the headline rate alone.
How development finance differs from bridging loans and commercial mortgages
Development finance, bridging loans, and commercial mortgages all use property as security, but they serve different stages of a project. Bridging loans cover short-term gaps, typically against completed or near-completed property, and are rarely suitable for ground-up builds. Commercial mortgages offer long-term repayment structures but require completed, income-producing assets.
Development finance sits between the two. It funds the construction phase itself, with drawdowns linked to build progress rather than a single advance. Lenders such as Nucleus Commercial Finance and Momenta Finance offer bridging facilities with terms from 3 months to 6 years, while development specialists like One Stop Business Finance structure facilities from 3 to 18 months, matching typical build timelines.
For a £500,000 project, the sequence often runs: development finance for the build, then refinance to a commercial mortgage or bridging facility once the scheme completes and generates income or achieves its sale valuation.
