Sold 90k OVER LISTING PRICE. (This market is literally insane.)

[Klint Ruud]

A client of mine recently listed a property in Nashville. She listed it high because we knew the market was insane and there were maybe 2-3 other comps to use to justify the listing price. Truthfully, there was fear of whether or not it would appraise. Within 18 hours she received multiple offers all over asking, one of which being 90k over the listing price and waived contingencies. I am completely dumbfounded. 

We've been saying it for months now but what do y'all think.... is this bubble about to burst?
