Buying my Fathers multi-unit apartment building

[Jasper Cangelosi]

My dad has been talking about selling his small 16 unit apartment building, we both have decided that I will take over the complex and he would even owner finance to keep it in the family. Is there a good way to make the transition without him paying so much in capital gains tax? And since he don’t mind owner financing I’m going to assume I’m in good shape paying very low interest? Thank you!
