1031 Exchange and Solo 401 (k) questions

[Michael Gust]

Hello Bigger Pockets Friends!  Looking for guidance on two questions related to single family detached rentals. 1.) If I sell a rental that I acquired using 100% qualified retirement money from a Solo 401(k) and immediately deposit the proceeds back into the Solo 401(k) would I have to do a 1031 exchange purchase or purchases to avoid capital gains or is this treated differently within a Solo 401(k) retirement fund/plan?  2.) Can the rental incomes from Solo 401(k) funded properties that flow directly back into the Solo 401(k) every month be treated as qualified contributions for tax purposes each year?

Thank you!
