Location, soils, regulation, etc all play a roll in what you have or need.

Have a vision, goals to get you there, be consistent, and stay healthy.

Yes, shenanigans and a healthy dose of tomfoolery thrown in for good measure. 

Keeping them clean and healthy is some work.In Seattle, I didn't have one request for a swimming pool.You don't say where you are or where you want to have rentals so, who knows how to answer our question? 

Of course, we only plan on living in CA for a few more years, so we're basically betting that we won't have significant damage before we sell and move.The type of construction (wood framed/cmu/steel, single story/multi story, etc.) and age of your buildings, the type of soil they are on, and the proximity to a major fault would have a significant impact on how likely they are to be seriously damaged in a quake.

Now, find what you need while you are young and healthy and if it someday allows you to invest with it Great.

The phase number increase as the detail of the site investigation increases usually where Phase II involves soil samples and other physical inspection methods.A leaking storage tank can cause environmental damage, as we all know, depending on what was stored in the tank and the degree of deterioration of the tank.

It's hard to say without having seen the damage and knowing more about the area, soil and normal issues for buildings in the area.

soil type?

@Ben LeybovichIf I was in your deal and there was a 2X on the property value at sale before splits , that would probably give me a healthy multiple (based on the waterfall details) and I could easily re-invest the larger sum into any dozen trusted GPS to regain different losses again that same year.
