I live in Cotacachi and have homeowners insurance from the Bank of Guayaquil. It covers fire, structural damage, loss of contents and theft protection with a $500 deductible. Homes may be better built these days, but the construction is still sloppy. The strength of the reinforcing bars that are used are diminished by up to 50% because of poor placement and embedment in the concrete. The short cuts that are taken compromise structural integrity. If you couple this with a lack of adequate compaction of the ground under the house, you will find cracks developing over time as the building settles. This being said, the mountain areas are fairly stable and I can’t see any catastrophic damage occurring except in a big earthquake.
If you have an account at Bank of Guayaquil, go talk to them.
