Why reading this list will stop your next deal from eating your margin
If you’ve done property deals long enough you learn the same lesson the hard way: the wrong type of finance doesn’t just cost interest, it destroys time, hobbles plans and turns tidy profits into headaches. This isn’t marketing copy – it’s what brokers and developers see after a rushed decision. This list walks you through five concrete differences between development finance and bridging loans that matter to the pocket, the timetable and the exit plan.
Read on and you’ll get: clear distinctions, realistic cost examples, lender behaviour to expect, a quick win you can use right now and a 30-day action plan to choose and secure the right product. Think of this as the checklist you hand to your accountant and solicitor so nobody surprises you at completion.
Quick Win
If you’re comparing options on a current deal, email both a bridging lender and a development lender the same one-page deal summary: purchase price, build cost, start date, expected exit and your experience level. If the bridging lender replies with a headline monthly rate and the development lender asks for drawings schedule and a CV, you’ve already seen the core difference – bridging is reactive, development is process-driven. Use that to separate serious offers from window dressing.
Difference #1: Purpose and when each product is the right tool
Think of a bridging loan as a short-term bandage and development finance as the scaffolding and payroll for the build. Bridging loans are designed to plug a temporary cash gap – buy-to-sell purchase, urgent purchase at auction, chain breaks, or quick refurbishment where exit is certain within months. They are not structured to monitor and fund a multi-stage construction project. Using a bridging loan as a long-term build fund is like jamming a temporary bracket into load-bearing structure – risky and expensive.
Development finance is built around the lifecycle of a build: acquisition, staged draws tied to progress, retention, and an exit strategy that could be sales, refinance to longer-term mortgage or institutional sale. Lenders expect planning permission, detailed budgets, build programmes and contractors. In short, development finance funds the work; bridging fills a timing gap.
Real example: a developer buying land with planning to build five houses should seek development finance with staged draws to cover foundations, damp-proofing, first fix and completion. A property investor buying a single flat at auction to flip in six weeks is usually better with a bridging loan to secure the purchase and cover refurbishment.
Difference #2: Term, exit strategy and the pressure of time
Duration and exit are where deals fall apart. Bridging loans are short and sharp – typically a few weeks to 12 months. Lenders expect a clear near-term exit: sale, remortgage or onward refinance. If you can’t articulate an exit clearly, the bridge will cost you in fees, extensions and stress. Development finance runs to the length of the build plus a short tail for sales or refinancing – commonly 12 to 36 months for small- to medium-sized projects. The key difference is that development finance builds in the project timeline whereas bridging demands a fast exit.
Imagine two scenarios: one, you need to complete a purchase this week to avoid losing a plot – a bridge secures it. Two, you plan a 14-month new-build – you need a lender that funds progress and inspects works, otherwise monthly interest on a bridge will eat the margin. The metaphor: a bridging loan is sprinting while development finance is a construction programme with milestones. Use the wrong pace and you trip.
Example numbers: if a bridge costs 0.8% per month and the build takes 12 months, interest cost stacks quickly compared with a development facility charging interest on drawn amounts annually and tailored draw schedule. Time is money, and the loan product sets the tempo.
Difference #3: Interest, fees and how they affect your profit
Costs are the blunt instrument that reveal the right product. Bridging loans often quote monthly interest rates (for example 0.4% – 1.2% per month) plus arrangement fees (1% – 3%) and sometimes exit or legal fees. Because the term is short, lenders price risk as a monthly premium. Development finance is usually priced annually (for example 4% – 12% per annum depending on sponsor strength and deal risk) and features facility fees, monitoring fees and sometimes a percentage retention. There are also monitoring and technical inspection costs that development lenders charge to ensure work matches draws.
Here’s a simple comparison table to make it concrete:
Concrete example: a £200,000 short-term bridge at 0.8% per month for 6 months costs roughly £9,600 in interest alone, plus arrangement fees. The same deal split into staged development draws might attract lower annualised interest on the actual drawn funds and monitoring costs, saving several thousand pounds and giving you more predictable cashflow. Don’t forget arrangement and exit fee structures – a cheap headline rate can hide a heavy exit fee that cancels the benefit.
Difference #4: Security, draws and the lender’s involvement in the build
How hands-on the lender gets is a defining difference. Bridging lenders often take a simple first charge and price the deal on the security value – the land or property you’re buying. Once on title, they generally stay out of the builder’s way unless you default. Development lenders operate more like project managers on the finance side: they insist on staged draws, independent valuations at each stage, and sometimes an inspector on-site. They also place conditions in the facility agreement – approved contractors, certified costs, snagging lists and retention sums until completion.
Metaphorically, bridging lenders loan you the car and let you drive. Development lenders loan you the car but also check the tyres, oil and schedule pit-stops. That extra oversight costs time and fees but it protects lenders and, if correctly managed, protects your budget too. If you run sloppy works under a development facility you will find draws withheld and progress stall – which can be more painful than a pre-agreed overdraft under a bridge.
Tip: when you’re planning, ask for the lender’s draw schedule and what evidence they require. A common stumbling block is contractors’ invoices that don’t match the lender’s schedule – insist everyone understands the draw triggers before works start.
Difference #5: Who can get the loan and what lenders actually look for
Not all borrowers are equal in the eyes of lenders. Bridging lenders prioritise security and demonstrable exit. Experienced investors with clear sales plans, or those with equity in the deal, find bridges easier to secure. Development lenders prioritise sponsor experience, build costs realism, planning certainty and exit plans. They will scrutinise your developer CV, contractor track record, build programme and sales plan. A first-time developer with large build costs and no fixed-price contract will meet resistance from development lenders – but may still squeeze a bridge if the asset value is strong and exit is near-term.
Practical example: two borrowers want £300,000. One is an established developer with a pipeline and confirmed materials supply and a fixed-price contractor – development lenders will offer competitive spreads and staged draws. The other is a private investor buying below market value to flip in a few months – bridging lenders will respond faster and with simpler security. Know your profile and present the documents lenders care about: proof of previous profitable projects, contractor contracts, planning permissions, cost schedules and exit contracts if available.
Analogy: the bridge lender asks, “Can I get my money back soon?” The development lender asks, “Can you deliver what you promise on time and on budget?” Answer each question in your application.
Your 30-Day Action Plan: Choose the right finance and protect your margin
If you finish this list with one takeaway, let it be this – match product to purpose. Below is a compact action plan you can follow in the next month to choose responsibly and reduce surprises.
Day 1-3: Clarify the deal facts
Write a one-page deal sheet: purchase price, estimated build cost, proposed contractor and contract type, start date, expected completion, and your desired exit. Add your experience summary and available equity. This single page becomes the baseline for all lenders you contact.
Day 4-10: Approach the right lenders
Send the one-page to two bridging lenders and two development lenders. Expect bridging to reply fast with headline rates and basic requirements. Expect development lenders to ask for a build programme, cost breakdowns, contractor CVs and planning documents. Use responses to shortlist the two best fits.
Day 11-18: Validate costs and contractor contracts
Get a second opinion on build costs from a quantity surveyor or experienced broker. If you’re using a development facility, secure a JCT or NEC contract with clear stages. Lenders will want this and it protects you from variations that inflate interest costs.
Day 19-25: Compare total cost, not headline rate
Ask each lender for an all-in cost figure for the expected term – include interest, facility fees, monitoring, valuation costs and exit fees. Build a simple spreadsheet showing net profit after finance costs. That number tells the truth.
Day 26-30: Lock terms and protect contingency
Choose the lender that matches your timeline and preserves margin. Negotiate a contingency buffer – 5% of build cost at minimum – and ask the lender how they handle overspend. If they push you into an inflexible product, walk away. Your job is protecting profit, not winning approval at any cost.
Quick Win to implement now
Before you sign anything, ask for a 30-day rate-lock or a conditional offer. Many bridging lenders will provide a short lock for a fee. Development lenders can issue a conditional offer pending technicals. A short rate-lock prevents a flurry of marketing calls and gives you time to model the true cost.
Final note from a straight-talking broker: lenders will always try to make their product sound ideal. Don’t be sold on speed at the expense of clarity. If the deal only works on a bridging loan because the expected build will take 18 months, reassess the build programme, the contractor and the exit. Protect your margin with honesty and paperwork – no lender can rescue a project that should never have been started.
