Selling the property within your Solo 401(k) and returning the proceeds to the account simplifies compliance and ensures tax-deferred growth (or tax-free in a Roth Solo 401(k.)).

i feel like RE is one of the best examples of the exponential growth or delayed gratification. the small things we do and the connections we make during our real estate journey seem so insignificant at the time. but it only takes 1 opportunity or one phone call to launch us to the next opportunity and then everything starts to build on itself.
