Well draining soil, flat topography, only 10 minutes from home.

@Skye Parker The water flowing under the house will erode the soil and especially around the piers where there will be more turbulence in the flow.The two main things I've learned from my experience here are:1.

Last Spring we purchased a single family home in Sandy, Oregon that said "Cash or rehab loan only" in the private remarks of the RMLS.

I don’t know much about that area, but living in NJ after Sandy, I can give you some things to look into.

But we have sandy soil , clay starts at about 12 feet .  

The environmental guy said due to its proximity to a large oak tree and the sandy soil he would advise leaving it only doing a clean out and seal so the tree wouldn’t have a chance to fall on the house.

Most people think of 3/4 crushed aggregate as if they don't need to apply some sort of "compaction" (aka density on non-cohesive soils)".  

Make sure you budget for time, consultations, removal, root raking, in-fill, soil testing, compaction testing, and tree replacement costs.

I paid the approximate $3500 for the soil borings and testing, but it paid off with no oil found.
