Capital Gains from the person selling to me

[Andrew Grimmett]

Hello all! :)

Someone I reached out to on an off market deal told me that they couldn't sell because they bought the property as a rental in the 70s and didn't want to pay the capital gains. 

I'm curious if this has come up with anyone else and what I can do to help the seller in the situation to get the deal? Am I able to help pay capital gains? Is there any creative ways the seller can get around this by selling to me? 

Sorry if these are dumb questions, but I guess I never know unless I ask!
