Flat areas east of Denver might have less ground work, but out west, site costs for grading and foundations (those darn clay soils!)

The plumber noticed 3 pans of dry grease near the sink while cleaning grease from lines last week.

Larry...most of the soil here has a very heavy clay base.  

Even if there are noticeable, persistent water problems, the grading around the house can be adjusted, and once it stays dry, I would just go in and refinish it - I just need to know if I need to account for that in any offer I may make or not.Thanks!

Luckily mold is rarely an issue in the dry areas I am.

A dry match. 

The combination of the soil and drought is not a good for the foundations in the area.

We don't want to use up all of our dry powder chasing a 14% cash on cash return when similar opportunities may yield much higher returns.

There are also good suggestions in this thread but more of your needs or desires would be necessary before someone could give you a cut and dried answer as to which method is better for you.

Just mix small batches so it doesn't get too dry.
