Everyones experience and risk tolerance is different, as well as different state, county and city law concerns variations. 

If the pressure drops due to temperature variation, then the pressure should rise again when the temperature rises.

@Jimmy Dudley you make a good point about the variation in markets surrounding bases.

Again, general rule, some variations.

Other variations include borrowing the down from my 401k, closing on a deal with a commercial loan, and then executing a seller financed 2nd mortgage that essentially reimburses me to pay back the 401k loan. 

Another variation is to have if XX sales are achieved for the next 3 years out of the 10 year lease then the personal guarantee goes away.If a landlord is really not smart the only guarantee you give is a remote single entity LLC that can be bankrupted and you walk away with no personal assets on the line.

Temperature variation across the length of the planks is probably contributing, an inadequate moisture barrier underneath, the contractor didn't seal the ends of planks near the door, or maybe there's not enough of an expansion gap between the walls and the floating floor in that area. 

I just get the vibe that other companies I've explored seem like a variation on the theme and the result would just be a different version of the same.

Similar variations exist in all other asset classes.
