They can tell you the citations that need to be fixed for it to be considered habitable.

California has a "Claw Back" law in place that could very likely make a 1031 exchange harmful in the long run. 

Like I said if you so not stand to lose or suffer what's the harm in giving them an additional month?

If we don't use it no harm done. 

Off-the-rack advice might work, but it does more harm than good often enough that I no longer engage in it.Absent any other information I would be planning for you to need money for another 30+ years.

I think you'll find that most serious investors who have been doing this for a long-time don't make a habit of screwing people out of deals.  

If your insurance covers loss of rental income that may be another source for capital during that time and may offset the cost of the hotel.If its going to take longer than a few weeks, you may offer to have them stay in another rental property if you have one available until the repairs are made.If none of the above options are available, then you may have to look at evicting because the house is not habitable and is too much of a liability.I would definitely exhaust all options to keep the tenants if they have been good tenants. 

Also, be mindful that with new law change of allowing the 1031 exchange only for the real properties, the cost seg might be harmful depending on if you want to ever do 1031 exchange.
