Hi guys,  for non US property you must always take the Alternative depreciation rather than the standard.  It used to be 40 years but recently moved to 30.  Also with depreciation you might actually not have a profit in the US but a loss so not FTC allowed but might have excess credits.  Depreciation is not allowed as a deduction in the UK so often there is a profit in the UK but not in the US.  If you wish to use the accrued method to claim foreign taxes this election is irrevocable so must use it for all future years.  The UK tax year ended on 5 April so you must use the tax due for the year ended 5 April 2023.  Another problem is that most properties in and around London are apartments so the landlord does not normally own the freehold but has a long lease so cannot depreciate the building but must amortize the lease over 99 years as most leases are more than 99 years.
