Bridging finance loans will always be secured against residential or commercial premises and in some instances even both. Payments are interest only so your monthly repayments are lower as you are not paying back any of the initial advance. There is also an option to roll the interest up into the loan so you have no monthly costs.
As bridging loans are a short-term solution, the interest rate will tend to be higher than that of a mortgage, hence bridging facilities are unsuitable for long term financing. However, Bridging loans can be highly useful when you need to arrange funds fast.
