JSG understands that securing project finance can be a challenging process, especially for those who are new to the development industry.

This is why JSG works closely with a range of development finance brokers and bridge finance brokers to help clients obtain the necessary funding for their projects.

Development finance is a type of loan that is specifically designed for property developers and can be used to fund the construction of new buildings or the refurbishment of existing ones.

Bridge finance, on the other hand, is a type of short-term loan that is often used to bridge the gap between the purchase of a new property and the sale of an existing one.

JSG also has a wide network of investors and works with housing authorities all over the country who can be approached for multi-dwelling properties that are developed.

This allows JSG to assist clients who may be looking to exit a property investment by finding suitable buyers or by providing guidance on how to maximise returns on their investment.

Yes, JSG has completed a number of large projects that have delivered more than 100+ units in single multi-class developments.
