What do I need to know before retiring in San Francisco?

"San Francisco is an expensive city to live in, so expats should plan their budget accordingly. It is important to research the different neighborhoods and find one that fits their lifestyle and budget. Expats should also be aware of the high cost of living in the city, including housing, transportation, and food. Additionally, San Francisco has a diverse population, so expats should be prepared to interact with people from different backgrounds. Lastly, expats should be aware of the city's climate, which can be unpredictable and change quickly," remarked another expat in San Francisco, the United States.
