Investors & landlords

It was sold and the capital loss was severe returning .13 cents on my original investment of $100k .  Over the course of 13 years I reinvested my interest rather than receiving it as passive income (have documentation of this).  With this it  more than doubled my original investment.  I know I can claim my principal investment of $100 k less the $13k (income when it was sold) yet what about all this compounded interest over the years, hence my question.   

Thanks in advance for answering this!
