The right finance solution for your circumstances will be determined by multiple factors including (and not limited to):

• the property type
• the project type
• your level of experience
• your credit file
• the amount of equity you have available
• whether you are using investors funds

When it comes to deciding which product is best for you it often comes down to a decision between seeking the highest leverage available e.g. borrowing the maximum amount you are able to or, seeking the cheapest rate.
