As long as you redeem the loan within its term, you will probably not pay back as much as the gross loan. Whilst the lender will place a charge on the property for the gross loan, they structure this as you ‘pre-paying’ the interest, so instead of you paying a £30k deposit with the example above, you are actually paying a £25k deposit and the other £5k covers the cost of the bridging loan, upfront.
What this means is that if and when you redeem your loan, if you have only used the loan for 100 days, you will owe back the lender the initial loan, the fees added and 100 days worth of accrued interest. Even though you may have £75k outstanding, your balance with them may be something like £72k, which you will pay back to them with your exit strategy and they will ‘refund’ you the other £3k for unused interest.
That can sound like you will receive a refund into the bank, you wont, they will just take the £75k charge off of the property for £72k.
