Should I sell my California house and move somewhere cheaper?

There is no single right answer; the better choice depends on your finances, timing, and what you want from the home. Moving to a lower-cost area can change housing expenses, taxes, insurance, healthcare access and proximity to family. Compare the full lifestyle and financial impact before selling solely because another market looks cheaper.
Use the future housing budget—not the old working budget
Calculate the full monthly housing cost after retirement, including the mortgage, property taxes, insurance, HOA dues, utilities, maintenance, and expected repairs. Compare that amount with reliable retirement income and the cash reserves that should remain available. A decision that releases equity or lowers maintenance can still create a higher payment if the replacement home, financing, taxes, or HOA costs are greater.
Stress-test the monthly cost
Compare the payment with retirement income under several conditions, including higher insurance, property taxes, HOA dues, repairs, and healthcare costs. Keeping a mortgage is not automatically good or bad; the important questions are whether the payment is sustainable, what cash would be used to pay it off, and how much flexibility remains afterward.
