The administrator has all the power, except that reserved by the court in your example, as they are appointed without what is called in my state "non-intervention powers".Typically in either case baring some other kind of limitation not referenced, the admin should have full authority to accept an offer before the auction, he would then just have to settle whatever contract he made with the auctioneer.I dealt with auctioneers that were both real estate agents and not, so the agreement we usually had was if we sell the property before the auction we had to use him as our sellers agent and he would take his REA commission, rather than the auctioneer commission. 

The property tax is administered by your local taxing authority, not the bank. 

I'm just not a fan of tenants putting them in without me authorizing it!

If passed, do you think this could potentially encourage San Diego authorities to impose rent control regulations?

Or should my husband list himself as the registered agent with myself being the authorized manager or is there a better/safer way around that?

If nobody is paying the taxes eventually it will get foreclosed on by the taxing authorities and you can buy it at the tax sale. 

.- If someone in your life that trusts/loves you adds you as an "authorized user" to one of their cards, often you will inherit the full credit history of that card - for better or worse (so pick a 10 year old credit card that they've never had a late on).

Check your taxing authority website.

I keep an excel log of pages and dates started and completed with author and publication.CCIM can be good info.

I've seen landlords get stuck with a chargeback on CC deposits and rents for various reasons.Some have suggested a landlord send an authorization form to the prospective tenant for their signature to avoid any shenanigans later.
