Capital Gains tax

[AUDREY DESOUZA]

Selling an investment property, that I purchased for little to nothing and  selling for over a huge profit, after renting for 5 years... what is the best way to avoid huge capital gains tax.  Do I have to buy another property with the entire amount that I make?  Any advise would be appreciated.  I was intending on buying  a couple of single family houses, but would it make sense to purchase a multifamily building that is more expensive?
