Building finance calculator for UK property developments
I can test how site cost, build cost, professional fees, contingency and completed value interact with my own LTC and LTGDV assumptions. The model shows the lower facility cap, indicative equity and profit before finance and tax.
My building finance model
Illustrative model only. Change the LTC and LTGDV assumptions to test scenarios. A provider decides eligible costs, value, gearing, fees, interest, releases, conditions and approval.
Model the site, build and completed value
I enter the gross development value, site cost, build cost, professional and other costs, contingency and the gearing assumptions I want to test. The calculator adds the modelled costs and applies both caps.
The lower of the LTC cap and LTGDV cap becomes the indicative facility. Equity is the gap between that facility and the modelled project costs. Actual eligible costs, value, gearing and releases are provider decisions.
Not included automatically
- Interest and arrangement fees
- Monitoring, valuation and legal costs
- Tax, sales costs and timing
- Provider-specific day-one and drawdown rules
How the building finance model works
Total cost is the site, build, professional and contingency inputs added together. LTC cap is total cost multiplied by my LTC assumption. LTGDV cap is completed value multiplied by my LTGDV assumption.
The calculator selects the lower cap. It does not decide what a lender treats as eligible cost or value. A provider may also apply limits to the site advance, borrower contribution, experience, planning, team, contingency and exit.
Documents behind a building finance application
Underwriting commonly covers the borrower, site, title, planning, appraisal, cost plan, cash flow, contingency, professional team, contractor, experience and exit.
Useful documents include the purchase contract, planning decision, drawings, schedule, quotes or tender, programme, professional appointments, proof of equity and sales or refinance evidence. Complete documents help assessment but do not guarantee approval.
What this calculator can and cannot tell me
It can compare scenarios consistently and show which of my two gearing assumptions is restrictive. It cannot quote a rate, confirm value, approve eligible costs, set release conditions or guarantee an offer.
Vortex is a property finance broker, not a lender. It can review the actual scheme and compare eligible development providers after I share the supporting evidence.
Compare funding for my building project
Share the site, planning position, costs, completed value, contribution, team, programme and exit. Vortex will compare eligible routes before I decide whether to apply.
