In principle, yes, a bridge-to-let mortgage could be used to purchase a holiday-let property. However, it will depend on the specific terms and conditions set by the lender. Some may have restrictions on the type of properties they will lend against, and holiday lets can be seen as higher risk due to their potentially variable income. After the initial bridging period, you would then need to refinance with a holiday let mortgage rather than a standard buy-to-let mortgage. As with any financial decision, it's advisable to consult with a mortgage broker or financial advisor to explore your options and find a solution that suits your individual circumstances.
