The following comments may be of assistance.
BostonDriver mentioned that the UK is cracking down on owners of property abroad. This is correct but not of relevance to travellerk. The changed UK tax rules relate to UK residential property owned by non UK residents.
The approach that travellerk should follow is-
• The position under UK domestic rules.
• The position under US domestic rules
• Any relief under the UK US double tax treaty.
Under the first heading, travellerk should therefore consider the general way that he is liable to UK tax. Presumably traverllerk is not UK domiciled but is UK resident.
Therefore, the rules on non-doms and the remittance basis are likely to be of relevance. The application of these rules would depend on how many years travellerk has been a UK resident and whether he is a remittance basis user. The nature of the investment, being US real estate is of secondary importance.
