Redfin shows that properties in this area are at risk of at least Heat and Wind advisories, some also seem to be highly susceptible to flooding.

This is one of the things that sound a lot easier than they are actually done.The crazy thing I learned about these CA fires is that the heat radiation is hot enough (1500-2000F) that it will ignite your furniture through the windows.

It is naturally insulated and it captures passive heat with strategically placed windows.

Also control the thermostats so the tenants don't jack up the heat in the winter giving you a massive bill.

There are two large community pools, which are heated during the cooler months, tennis and pickle ball courts.The minimum STR period has been reduced from a year to six months.

Windows would be my next check-point (less than R1) and then wall insulation: I would not be surprised if they have no insulation inside, but you can do blow-in, which only requires a small hole.A home looses heat in two ways: heat conduction (which you can slow down with insulation) and drafts, which in old houses is usually the biggest culprit.

This is the simplest method, but it also means your tenants are more likely to abuse the utilities by leaving windows open with the heat or A/C running, leaving lights on, ignoring the toilet that constantly flushes on its own, etc.3.

We heat and keep the doors closed and don't have issues normally.

Estimated cost for remaining changes (all new electric, drywall, tile, fixtures, cabinets, roof, doors, windows, heat pump, some siding, and fencing.

@Alecia Loveless is correct--tenants need access 24/7 to their electric service panel, water and heat, assuming those are individual utilities for each unit.
