But your primary home isn't an investment, it's a necessity. You're going to live somewhere. The only choice you have is whether to buy or rent the place you live in. So that's the comparison that should be made. Comparing your primary home to your stock portfolio is pointless because you can't live in your stock portfolio. The GP is pointing out a key advantage of buying your primary home vs. renting: you're not exposed to the risk of rising rents. Others have pointed out disadvantages, such as being exposed to the risk of rising property taxes and rising insurance costs. How those things balance out is going to depend a lot on where your home is.
