Any numbers used in such analysis needs some major sensitivity analysis around it. Probability analysis as well.

If the assumption is that inflation is 2.5% then consider what if it were 10% suddenly?

If assumption is that you won’t need to move for a career opportunity for 5 years, what if it were suddenly 2 years?

If assumption is mortgage rates will stay this cheap, what if they double instead.

Bracket the possibilities and consider the consequences of each. It isn’t as simple as a straight up calculation. And the numbers, probabilities, and consequences are different for everyone
