How We Work

Development Finance
Securing finance for a residential development project can be a complicated and laborious task. Each project is unique in its specifications and each lender is selective in their lending criteria. Knowing exactly how to package your project and who to present it to can save you time and frustration.
With our expansive network and extensive industry experience, we are able to quickly and efficiently secure senior debt, stretch senior and mezzanine finance from our roster of banks, challenger banks and non-bank lenders.
We ensure a smooth and well managed process where we will assess your project and produce a funding package, complete with our own financial models, to take to potential lenders and secure you the most competitive offer on your finance.
We will liaise with lawyers, valuers and surveyors, giving you the freedom to focus on what you do best – developing.

Development Equity
Many of the most successful developers will have more profitable projects available to them than immediately available capital. Having all your capital tied up in projects can be the one factor holding your organisation back from rapid expansion.
We work with a variety of equity providers that can provide this element of capital required to deliver viable, profitable projects.
Our equity partners include family offices, registered funds, private companies, High Net Worth Individuals and Sophisticated Investors.
We assist in structuring equity agreements with appropriate development finance partners, sourcing you the equity needed to take advantage of all the opportunities presented to you.

Development Joint Ventures
Development joint ventures can be a creative method for ensuring you can secure the funding you need to develop your next project and expand your property business.
Whether you are an experienced developer in need of a silent partner to provide 100% of your costs, or an inexperienced developer needing an active partner to provide you with guidance and the bank with comfort, a joint venture could be the most appropriate vehicle for you to maximise your profits and minimise your risk.
We have excellent connections with a number of individuals and organisations interested in taking this more collaborative approach.
