Can 401k inheritance be rolled into self-directed IRA for RE

[Susan Marr]

The deceased parent was under 70 but of retirement age. Two children siblings are the beneficiaries. There is a property both siblings would like to purchase 50/50 ownership in full cash in its entirety using about 75% of the amount in the account. They both plan to open up self-directed IRAs to defer tax and purchase this property. If taxes were paid upfront, barely enough money would be there to buy this investment property. Should they set up separate self-directed IRA accounts or just one? Also, the new SECURE act makes it so all money must be withdrawn in 10 years. Is there a way to pay taxes on the property each year so that at the end of the 10 years it is owned? It may not be sold. Is it only possible to wait until the end of the 10 years to pay the taxes on the money used to purchase the property? What are the tax implications? What would you do in this scenario? Bigger picture, there is also a house that needs to be sold (but may go to some sort of probate or something...unsure)so there will be some cash inherited from that. But who knows how long that might take, there isn't a lot of time to get the cash together for this opportunity.
