Where to put inheritance to be able to use for Flipping business

[Doug Rich]

We are about to inherit our seed money for our flipping business, it is coming from a 403b account, misc IRAs (which are becoming inheritance IRAs), and sale of a single family property.  As we understand it, the distributions for the 403b and the profit from the house will be taxed as income only, still we would rather stretch it out over a few years if possible to pay the minimum taxes possible, but still be able to access in a way to start leveraging for flip properties.  Any and all suggestions apperciated.      Thanks   DnD
