Thankfully, if there is a treaty for the avoidance of double taxation covering real estate capital gains taxes between both countries, the foreign investor in the US can credit his US taxes against his domestic taxes.

If so, there are 20+ accountants on this site that specialize in real estate taxation. 

Any and all distributions from inherited IRA will be subject to taxation. 

@Eric DritzMortgage companies normally do not issue mortgages where title is owned by someone else.Regarding taxation, partnerships are required to file a partnership return.Partnership returns are due March 15(calendar year) with the ability to extend it to September 15.

I would prioritize finding an accountant who specializes in real estate taxation over one that is local.There are 20+ accountants on this message board who specialize in real estate taxation.

Talk to a qualified professional or two.Again, the partnership taxation is a pass-through entity. 

As the laws both from a taxation point and landlords rights are very different per province and obviously different from the US market it’s really difficult to find a good tax accountant who a) is used to working with investors and b) is allowed to practice in both provinces and c) understand the “gottya’s” and can guide you. 

Either: (1) withdraw the excess contribution along with allocable earnings; get hit with taxation and a 10% early withdraw penalty on the earnings (most likely), (2) re-characterize the contribution to a non-deductible Traditional IRA, file Form 8606 with your return, maybe do a back-door Roth soon after if you won't get dinged by the pro-rata rule...or...just leave it as is and track the basis you now have in your traditional IRA, not as big a deal as people make it out to be... (3) pay the excise tax and hope the over-contribution can be remedied over time through the absorption method.
