How is the roof, the mechanicals, water issues?

I'd also look to see if water is getting in or if it was just a problem with humidity.

Our waste water goes to Mexico, maybe that’s what they meant?

We needed an upgraded 200amp electrical panel ($5-8k), extended water and sewer for the garage ($5k), built out interior ($7k?)

And if their house is vacant, you can probably get the city/water company to turn off the water to the property.

What are the best coverages and limits to have in insurance policies to cover edge case scenarios like these Insurance Policy with water, mold, vandalism, pest etc. 

So here is the first thing that doesn't make sense:How can anyone try to convince you that the foreclosure list, absentee owners list, job loss list, water shut-off list, tax lien list, and probate list are "good lists" when 999 people out of 1000 on your list are not motivated to sell?

. - 5% of agents "walk-on-water".

Check with town permitting or GC if need additional parking, landscaping and rain drainage.

No question RE is a long game and those who try BRRRRR (I add the last R because there should be one called "Reserves") with $200 cash flow in low cost areas are generally going to be blown out of the water in short order.
