Hi L-I Am,
We have a specific department who deal solely with non resident landlords.
I have consulted the property income manaul and I believe a technician in this place would have to consider your 'usual place of abode'
However as this forum does not deal with this issue I believe the NRL department might be better equipped to answer your query relating to armed forces.
I have attached some guidance for you to consider in the meantime, this may answer your query, the telephone number of non resident landlords is 0300 322 9433
Non-UK resident landlords
PIM4850 - The Non-resident Landlords Scheme - usual place of abode
Thank you.
