Avoiding Capital Gain Tax

[Steve Milka]

First post and hope this is the right spot.  I have been on here for a while reading, listening and looking around and have a question that maybe someone can help with?  We have had a rental property in Denver that we lived in for 3 years and have rented it after that.  It has been rented out since 2014.  With that being said we moved out of that property and bought property 2 and stayed in the property 2 for just over two years and sold it to get our cash out of it.  Since we were in it for two years we didn't have to pay the cap gains tax.  This was on the tax filing in 2017.  We were thinking of selling the first house that has been rented out this year and thought we would be good on the cap gains tax again but now I am reading that you can only get this tax break every two years.  Do we now have to wait until next year to sell to avoid the taxes?  Any input would be greatly appreciated.
