Personal Allowance for Swiss citizen living in the US

I am a Swiss Citizen living in the US. I have a rental property in the UK, and have been filing yearly tax returns in the UK declaring the rental income. I have to date not claimed the personal allowance. Am I eligible for the personal allowance under the UK-Swiss double tax treaty? Thanks!

Hi,
Please have a look at the guidance for box 15 on pages RRN4 and RRN5 on the notes for supplementary page SA109 (Residence, remittance basis etc notes).  
Please also have a look at helpsheet HS304  Non-residents tax relief under double taxation agreements (Self Assessment helpsheet HS304)
Thank you.

Not HMRC...per HMRC's reply...youd need to be a national and tax resident of Switzerland (residence in US may ne an issue unless tax resident in both countries?)
