However, if we look at living in California these days.

I gave the house a harmonious name, & so far it has cash flowed from day 1. 

Stop hanging out with your deadbeat buddies who spend all day drinking, talking sports, and otherwise wasting away.

Once the construction of the business building was far enough along (but no more than 180 days) that the price of the land and the amount of improvements you make on it are equal to the sale of your old investment property you take title to it and that would complete your 1031 exchange. 

Many CA investors like to invest in NV and AZ because they are close by making it easier to travel to and from in 1 day.

For example, most anywhere will get $700 room, $75 fixed rate utilities, $700 deposit, and then offer a 36 months, 12 month, or month to month lease ($350 fee if ending lease <90 days). 

Yes, you can deduct the 8 days rent from the security deposit.

Here is some info: SF STR FAQAssuming the info is up-to-date, it must be your permanent residence (you must live at the property for a minimum 275 days a year), you can rent unhosted a max of 90 nights a year, you need a business license, and you need to pay the city $925 for a STR certificate.

Thank you for taking the time to read this post, have a wonderful rest of your day😊.

@Tom OchiengI would reach out to a real estate attorney for specific advice on this situation since you already have one tenant who is being difficult.On a side note, when I have inherited tenants, I have been most successful when I have provided longer non-renewal notices, like 60-90 days, and offered to assist with moving costs.
