Your stock market losses are treated as short-term capital losses.
Your gain on the sale of the rental property is treated as ordinary income since you held the property for one year or less.
As a result, there is no direct, one-for-one, offset (as there would be if both received capital gain treatment). You can only use up to $3,000 ($1,500 if married filing separately) of the stock market losses against all other income.
