I have some basic knowledge about the subject.

So, if I withdraw $60K, about 75.24% of that should come from contributions (since that’s how my balance is structured).75.24% of $60K = $45,014 → Comes from contributions (no tax or penalty)22.38% of $60K = $13,428 → Comes from earnings (subject to taxes & penalty)Taxes & Penalty on the Earnings Portion ($13.4K)Federal Income Tax (24%) → $3,219Early Withdrawal Penalty (10%) → $1,342Total Tax & Penalty: $4,562Net Cash After Taxes and Penalty Fee: $55,437The DilemmaIf I leave the money in my Roth 401(k), continue contributing $525/month, and earn 8% annually, my balance could grow to:$229,865 in 10 years$606,905 in 20 yearsBut if I buy the property, it could generate $15.6K/year in pure cash flow, plus appreciation.

@Thelma Bal Best content on Cost Seg, bar none, is @Michael Plaks' posts on the subject.

Just know that if you are moving somewhere to chase the hot market, it will only stay hot for so long.

Research the sponsor's track record, past performance, and the market they’re investing in.Understand UBIT/UDFI – If the syndication uses leverage, your SDIRA might be subject to Unrelated Business Income Tax (UBIT) on the leveraged portion of the income.

There are plenty apartment buildings, the issue is finding them at the right price point - as in any hot market. 

Well, what would be happening is that your buyer would be buying your house subject to the existing note, since you can't legally sell the property without paying off that note or transferring the debt to the new buyer.

I don't care what kind of business it is, STR, Hot Dog stand, any biz I am NOT paying 8X annual gross revenues, no flippin way! 

But if you did the property up right with killer design and great amenities -- I'm picturing cool wallpaper, a game room, boho/modern furniture and a hot tub -- I can see a place here doing well as an affordable Airbnb/STR option just 10 minutes to downtown Denver.

A hybrid deal in this case would just be taking over the house via subject to and then having the seller carry a portion of their equity in a 2nd position lien.
