Why VFIAX over VOO? does buying a foreclosure mean buying a house for cheap after the owners were unable to pay for it?

[blaser-waffle]

VFIAX is "Admiral Shares" and has a lower expense ratio compared to VOO. But it also requires a higher minimum investment -- $80k is over that limit.

Even if OP splits it into smaller, dollar-cost-averaging purchases they'll still be able to get VFIAX without a problem.
