No single lender funds 100% of a scheme. "100% development finance" means senior debt plus a joint-venture partner or mezzanine lender funding the rest — usually in exchange for a large share of profit. It can make sense for a strong site, but it is the most expensive capital in the stack.

Rate context and outlook
Senior development finance currently prices from about 8.8% a year for low-leverage ground-up schemes, with most facilities at 9.5%–12%. Bank Rate is 3.75% after the 17 September hold; development lenders price off their own funding costs, so rates have stayed stable through the September swap-rate rise, and some lenders cut margins over the summer.
Lenders now expect tighter information on build costs, drawdowns and exit before committing.

Frequently asked questions
Is 100% development finance available for first-time developers?
Rarely; JV partners want a track record or a very strong site.
What do JV partners take?
Typically 40%–60% of profit, sometimes with a preferred return first.
Is mezzanine cheaper than JV equity?
Usually, if the scheme is profitable, because mezzanine charges interest rather than a share of profit.
How are funds released?
In stages as the build progresses, usually in arrears, after a monitoring surveyor confirms the work is done.
Do I need planning permission?
Senior development finance usually requires full planning; sites without it are funded with land bridging first.
How long does it take to arrange?
Usually 4–8 weeks, depending on valuation, the monitoring surveyor and legal work.
What is the difference between LTGDV and LTC?
LTGDV compares the loan with the finished value; LTC compares it with total costs. Lenders apply whichever is lower.
What if the build overruns?
Lenders expect a 5%–10% contingency. Overruns beyond it are usually funded by the developer, or by agreeing an extension.
