I would say that the first step before panicking and talking about sale is to request, if not demand, an explanation of the problem and solutions needed to correct it.That value seems really suspicious, especially when added to the fact of the extremely large assessment last year. 

I have numerous SF rental properties in the Houston area.  

It takes hours just to do the basic vetting of a single investment, so it would save incredible amounts of time to have all of that done in advance, and an accurate rating of the risk placed on the investment (A, B, C, D).On the other side of the coin: numerous platforms claim they are simply awesome at doing pre-vetting, but in my opinion, what I see in practice doesn't match up to the words.

Logan Allec, very nice explanation, well done !

,etc. from there you will either get a door slam(im assuming) or a okay, or a explanation a little.

Tried numerous ways with spaces etc.  

Additionally, if the properties are not owned by a bank free and clear the setbacks and roadblocks can be numerous.

It didn't take that long as have done numerous renovations and have been in and around the trade and have a great group of sub contractors. 

If I were in your shoes I would demand to get a better explanation and see what happens.

To counter several arguments I get from this explanation:"I'm not selling anything on my blog."
