My parents want to leave me and my spouse their house. How do I prevent ‘tension or resentment’ with my siblings?

Dear MarketWatch,

My spouse and I are looking to buy a house. 

We are the only ones in our family who don’t own a house yet, and our parents have offered to “sell” us their house as they move away, as long as we work it out with our siblings. 

Our parents generously noted that otherwise the house would be an inheritance…
