You have 24 hours to accept a pre-approval before it expires. If more than 24 hours have passed, you can still accept the pre-approval, but your host will need to approve your request before your booking is confirmed.
Most of the time when an Airbnb host receives a booking request, it is coming from a guest who is genuinely interested in staying at the property. Unfortunately, there are incidences where hosts receive booking requests that are meant to scam the host.
Yes, you can rent out a house you have a mortgage on, but you'll need to inform your lender to ensure you meet the necessary requirements. There is nothing against the law about renting your home while you still have a mortgage. However, different lenders have different rules when it comes to occupancy.
How much can I make on Airbnb? A simple way to calculate your Airbnb revenue is by multiplying the year-round occupancy rate and your average daily rate. If you charge $150/night and achieve a 70% occupancy rate, you will make around $150*0.70*365, which is $38,325 before expenses and taxes.
