Your sibling can use a 1031 exchange to defer capital gains taxes on the sale of the rental properties by reinvesting the proceeds into like-kind investment properties.

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.)).

My business still needs to sustain itself.  

I know I would get bored with not having a job or business to do lol

And, again, eventually a strong business model/niche will show its numbers and then everyone will be doing it.

My wife and I are a team in our business too.

My husband and I plan to use the proceeds from our sale to purchase a larger business in a few years using an SBA loan.For those interested in exploring entrepreneurship through acquisition, I think laundromats are a great place to start.

If you're going to reinvest the proceeds you might want to consider a 1031 exchange or a cash out refi to generate the investment funds you desire for your next project.

Excited, and honestly a really nervous, to be diving into the flipping business!
