Yes it will - you can split stocks/financial portfolio way easier than you can real estate. If your heirs don't get along, leaving them to split the house, especially if they're not well off, is a recipe for giving money to lawyers. Forcing your kids to sell their childhood home in a time of grief just seems cruel. Passing down a financial portfolio with specific shares/dollar amounts is much more straightforwards.

Again the difference is though that if you are renting that money is not going into your net worth. The principal from your mortgage is. Concern about difficulty with handling it is resolved by having a good will that makes preferences on how it should be handled clear.
