This is an emergency situation.Regarding further protection, it gets messy and confusing.

My current W2 is an Emergency Room Nurse in San Francisco.

Had to cancel my trip in the last minute as my wife is in a medical emergency.

Suggest saving the money though, for possible emergencies, and then paying down the loan at the refinance closing.This may take 12-24 months, so how badly do you want to invest to build wealth?

I keep 100k in real estate reserves and have another 200k in lines of credit should I need to tap for emergencies.

Having your handyman do showings could be a solution, but keep in mind that if he’s not experienced in tenant screening, it could expose you to more risk, especially with squatters or less reliable tenants.You mentioned using something like Showmojo for smart access, which is great for efficiency, but I’d suggest ensuring you have solid procedures for background checks and tenant screening if you go that route.As someone who’s owned a property management company for 5+ years and manages over 300 units, I’ve seen the impact of not properly screening tenants.

I suppose that requires a second (or third or fourth) opinion, but if he's right, where can I pull cash from to both complete our primary home, and refill the RE emergency fund I'm currently depleting?

If you don't have any liquid reserves, you should build up 6 months of expenses as an emergency fund (in case you get laid off, disabled etc).

He wasn't giving into the state and local governments mandate for employees to be forced to wear masks, get vaccines, etc and he started getting "threats" saying that he could be taken to court and have assets seized if he continues "breaking the emergency laws" during covid time.That could be viewed as an extreme example, but things like this worry me as I have my own company and employees.

Adhering to the procedures laid out in the operating agreement is what you rely on to be viewed and treated as a business rather than as an individual.
