Capital gains tax questions on primary residence (only property)

[Gabriel Smith]

Hi BP investors! 

My name is Gabriel and I'm brand new to all of this and looking for a way to get started. I have about 90K in my primary residence and my wife and I are thinking about bitting the bullet and moving in with family and selling the home to save some money and get an investment property. 

Will I face cap gains taxes if I don't reinvest right away? Any other advice?

Thanks!!
