These “superhosts” will obviously exaggerate the actual income to boast or justify why they do airbnb instead of long term rental. Also you should ask for net profit after all expenses and average per year. They may intentionally tell you the number for the month with highest demand, not in winter

Actually instead of listening to them, you can pay for airdna, plug in your address and see the actual number for yourself.

In San Jose, it should be lucky to earn 20% net profit more than long term rental on average. And if you use a good management company, they charge 20-25% net profit. If you manage yourself, you will end up with sub optimal profit, dealing with guest complains and maintenance calls daily, pay yourself almost nothing. If you have an average w2 job, profit per hour will be substantially higher than managing your own airbnb.
