Avoiding Property Gains Tax

[Account Closed]

Hello everyone. We are in the process of developing a few commercial acres. We have two buildings going up that will be offered for sale or lease. This is not our main business. If we were to find a buyer for the properties, without rolling over the gains into another property is there a way to avoid a portion of the property gains tax? Is there a way to purchase equipment, vehicles etc. and write a portion of the cost off? Any help would be appreciated.
