A lis pendens indicates that a foreclosure lawsuit has been filed, marking the property as legally contested and likely in preforeclosure.

I have gotten taxes reduced by contesting the value of the B-C properties. 

The person has threatened to contest the quit claim if I try to sell, a credible threat given their history.

True, as Borja and Erwin suggested, banks are much more flexible in the US than in Spain but what matters way more in wealth building is the level of interest rates and there is no contest there.Normally, banks worldwide only lend to their own citizens, there are citizens and there are Spanish and American banks that will lend to non-residents.A Spanish resident could get an interest rate as low as 2.5% and a non-resident would pay 2.9%.

You have to do security doors and windows due to theft.Visited the neighbors across the road, who were having a roping contest. 

Have you contested this with the HOA at a formal meeting?

I know someone whose will was contested and they lost and were told that if the decedent had made a video explaining their choices, it would have made all the difference. 

Any help, advice would be greatly appreciated.Probably too late this time, but always contest your assessed values.

That's totally on you and you don't appear to be contesting that.If I were Tenant, I would think you are punishing me for suing when you end my lease, so I'm going to sue you and the insurance company for 10x my original plan.

Contested evictions can be significantly longer.Even in states often cited as very landlord-friendly, like Texas, there are trade-offs.
