It depends on a few factors:
First, the fires. They are really changing the shape of the city and it may become incredibly expensive to buy out there soon due to lack of housing. Which may also be a reason to hold on to your current place (appreciation).
Second, have you been in your primary at least two years. You would have had to be there for at least that to save on the capital gains taxes (up to 250k).
Third, do you have a lot of equity? If not I wouldn't bother selling as there is an incredible amount of money lost in buying and selling properties, so you have to make sure you have a plan to maximize the equity and actually have enough.
Forth, what is your interest rate? If you have a great rate, I would not be looking to refi, maybe a HELOC instead.
You may just want to put 3% down on your next place and rent out this one. The numbers may not be that favorable in LA for this, I don't have enough information.
I hope you are staying safe in this difficult time.
