As an expatriate there is a high chance that you'll wish to let your property at some point in the future. If this is the case you are presented with two mortgage options.
Apply for a residential mortgage with permission to let added into the contract as a specific clause in the formal mortgage offer.
Apply for an expat Buy-to-Let mortgage from the outset.
The main differences between the two schemes are cost. Residential mortgages generally have lower rates and charges than buy-to-let mortgages. The other point to consider is your residential rights. If you take out a buy-to-let mortgage you cannot use the property as your own residence should the need arise in the future.
If you are applying for a mortgage to purchase your first property in the UK or you are intending to return back to the UK to reside at the property within the next 5 years, then a residential scheme with permission to let should be your first consideration.
If you are purchasing a property purely for investment purposes and you already own other property in the UK, or do not intend to reside in the UK again, then a Buy-to-Let mortgage is probably your best option.
There are obviously some major decisions to be made surrounding which of the two options would suit you best. It is advisable to discuss your current intentions and situation with one of our mortgage advisers before committing yourself to either scheme.
