Capital gain on oversea real estate

[qwer1234]

I purchased an apartment overseas nine years ago as a US non-resident. The apartment value increased before I moved to the US with a working visa. 

I obtained a US green card in recent years and sold overseas real estate this year. Can you suggest calculating the long-term capital gain, particularly on the cost basis? Thanks!

sales price is what it is but needs to be converted to US $ see

cost basis

what you paid + closing costs converted to US $ for the year of purchase plus

capital improvements converted to US $ for the year paid plus.

selling expenses converted to US $ for the year of sale

I was not a US resident when purchasing the apartment. Its market value appreciated before I moved to the US. Can I use the market value at that moment as the cost base? 

Also, can long-term capital loss in stock markets offset this capital gain?

No.

Yes.

Were there any loans/mortgages on the property?  You could also have a gain or loss due to currency conversion with a loan.  If that is the case, you'll want to go to a tax professional that specializes in Nonresident Aliens and/or international taxation.
