Use current value to decide whether the next move is worth it
If you are debating a move for more space in Irwindale, CA, I would answer the question by starting with your current value, not your future wish list. The latest typical estimated value was $756,240 last month, and that is the number I would use first.
A larger-home decision has to start with the value of the home you may be leaving. In Irwindale, CA, a typical estimated property value was $756,240 last month, compared with $777,470 one month earlier, and the 12 month change was -3%.
That creates a useful reality check. I would not let the appeal of more room push you into a move that relies on extra equity beyond the current value range, because the comfort you gain in space can be offset by financial strain.
Rebuild the math using today's value. Decide which space problems truly require a move. I would make sure the solution improves both daily life and monthly comfort.
