Dollar Value changed in foreign home sold

My wife just sold her house in Brazil. She strictly used it as rental property. She bought this house at R$100,000 (R$ is Real Brazilian currency) which is USD $44,152.06 in 2013.  She sold it at R$150,000 which is USD 28,327.54 in 2025.  You can see that she made R$50,000 in profit but when I do taxes as jointly, it showed loss in dollar for sold this house.  The dollar value has changed significantly in 12 years. What should I do since it's a loss in Dollar but gain in Real (Brazilian)?

 

Another question is that she used as rental property in whole time, she never use it as main residence. Do I have to report it on Sale of Home?

 

Any advice is appreciated!
