How Development Finance Rates Work

Partly due to the added costs involved with development finance and their specialist loan structure, development finance interest rates are often higher than other forms of property finance. Development finance rates are often calculated on a monthly or yearly basis and can sit around or above 1% interest monthly.

Development Finance is often on shorter terms. Our financing terms typically range from 4 months to 2 years. To account for unforeseen delays, we always provide a minimum extension of 3 months beyond the projected cash flow period.

How To Get The Best Property Development Finance Rates

The rates of development finance loans are calculated and vary due to a number of factors: 

Gross Development Value (GDV): 

The projected value of your project upon completion plays a role in determining the interest rate. Higher GDV projects may qualify for lower rates.

Loan Term: 

The duration of the loan can impact the interest rate. Typically, longer-term loans might have higher rates.

Developer Experience: 

Your track record as a developer is a key consideration. Experienced developers may secure more favourable rates compared to first-time developers.

Loan Amount: 

The size of the loan can affect the interest rate. Larger loans may qualify for more competitive rates. Loan to Cost (LTC), the size of the loan in comparison to the complete cost of the project, will also affect the rate of your loan. 

Development Location: 

The geographical location of your project matters. Some lenders may offer different rates based on the region, and not all lenders finance projects in every area.

Project Complexity: 

The intricacy of your development project could influence the interest rate. More complex projects might be associated with higher rates.

Type of Financing: 

Different types of financing, such as bridging loans, mezzanine finance, or joint venture finance, may come with distinct interest rates.

Deposit Size: 

The size of your deposit, particularly in commercial projects, can impact the interest rate. Smaller deposits may result in higher rates.

Credit History: 

Your personal and business credit history is a significant factor. A strong credit history may lead to more favourable interest rates.


To get the best rates, a good track record / credit history, a large deposit and a clear plan for what you intend to develop, will put you in good stead. Consider speaking to a broker, rather than going directly to a lender, as they may be able to garner you better rates on the same investment.

Covers the cost of a professional surveyor or valuer assessing the property’s value and condition. Cost can vary, but may range from £1,000 to £2,000.

Legal Fees: 

Involves hiring a solicitor to handle legal aspects of the loan and property transaction. Cost varies and includes both your solicitor’s fees and the lender’s legal fees.

Surveyor’s Fee: 

Needed to estimate the Gross Development Value (GDV) of your project. Could cost around £1,000 to £2,000.

Exit Fee: 

Charged by some lenders upon repaying the loan, usually 1-2% of the loan amount or GDV. Cost varies based on whether it’s against the loan amount or GDV.
