@Forrest Brown,  I'm never a fan of telling anyone that writing a check for taxes is the best idea, but it does depend on your goals and your potential tax liability upon sale. 

Without that you can be sued personally for any issue within it on your str.Its much harder for people to pierce the corporate vail and sue you personally if your property is owned and managed in a LLC .Financing is one of the only drawbacks as it is a commercial process and banks usually like to see 3 years of a decent tax return.We have 19 properties and all are in an LLC and in fact we only hold 2-4 properties in each LLC (all are owned by one parent company and done in one flow through parent company)to even further shield the liability that may/can occur on a property.There is no doubt you are exposed to higher risk on many fronts if an investment property is held personally.

They are violating the lease agreement by having others live there who aren't on the lease, this is a real liability concern with your insurance so that should be addressed. 

This was common in FL back in the day but no longer as most title companies won’t do these transactions anymore due to the liability and in many states (if not all) due to the fact it is no longer legal.

However, I am wary of the maintenance cost and added liability that comes with these amenities. 

Do you carry liability insurance?

Then my tax liability goes way up and capital gains tax on the Bay Area SFH will be huge if I got out of RE. 

Once again these products aren’t cheap, but they perform well and will save costs associated with having to repair a failing waterproof system down the road...like many developers, though, who don’t give a **** about their buildings lasting longer than the time they can sell and any liability lasts, this type of system may not be wanted

I strongly suspect your best move is to roll the TSP to a Traditional IRA and convert the IRA to a Roth, using non-retirement dollars to pay the income tax, even if you have to borrow the tax liability.

However, it's essential to maintain proper accounting records and ensure that personal and business finances remain separate to protect the limited liability status of your LLC.Value-add properties often require initial investments for improvements, and it's common for investors to face similar situations.
