In Australia you definitely can as I had that experience some years ago.

As you failed to say where you live I can say no more except it is always good practice to give your country/state of origin on a world wide site.

 In your case all you needed extra was "in bullamakanka"

I could be wrong but my answer would be: It depends. 

You might possibly have a gain on the a rental property that you sold for at a loss.  For example, if you bought a rental property for $100,000 and subsequently sold it for $90,000, you have just realized a loss of $10,000, right?  Not necessarily.  You might have to adjust your cost lower than $100,000 if you have depreciated the property by $25,000 over the years.  Since you took depreciation of $25,000 over the past few years, your new cost basis would be adjusted to $75,000, or $100,000 - 25,000. 

Hence, if you sold the property for $90,000, your taxable gain would be $15,000, or $90,000 sales price minus new cost basis of $75,000.
