@Ty Miller and @Aaron Brown -- I'm a fellow Missourian and in fact, my daughter is a 5th grade teacher in Independence School District.

Nobody knows what the reinforcement inside the gradebeam consists of, so nobody can do anything other than guess, based on their experience with similar stuctures in the area, what the maximum span between the piers can be before the grade beam collapses.

If the ad mentions "basement", it's not slab on grade!

How old is the house if this has gradually happened over 100 years it may not be an issue, if something changed and it's sunk 1.5" in the last 3 months say due to the massive amount of rain we've had you may have a grading issue.  

Slab on grade vs pier and beam is pretty different IMO

We then added drainage and graded the yard so that water could not get under the foundation anymore.I would say that depending on what team you put together its not 30k.

I've also found single story homes with a slab on grade reported as requiring a pier every 8', not the 6' I was quoted on another repair company's site (so still an interested party's opinion, but still more reasonable by 25% given spacing). 

Macroecomics is way above my pay grade!!

I think more speculative commercial will get harder to finance with loans.NNN investment grade credit tenants will still get awesome loan rates as the banks have less inherent risk in those types of deals with long term leases.
