The following covers the Roth IRA conversion rules. https://www.irs.gov/retirement-plans/retirement-plans-faqs-regarding-iras-rollovers-and-roth-conversions

If you want to do flipping inside a retirement account, consider using the Rollover as Business Startup (ROBS) as it is not subject to UBIT. 

Businesses sponsor retirement plans as employee benefits.You can rollover existing tax-deferred savings into the Solo 401(k) as well as make new contributions into the plan based on income via your flip/wholesale LLC.The Solo 401(k) can invest passively in real estate, so long as those investments are kept very separate from the other personal investments you are making with non-retirement funds.When it comes to Solo 401(k) providers, there are document mills and true advisors.  

Long story short, you'll basically be setting up a situation where you get some kind of temporary financing to fund the construction to then roll over into the VA loan once complete.

You could still fund a SD IRA and your company's 401K plan at the same time, you just wouldn't have the benefit of the rollover contribution.Another thing to look at when you're doing your research is a solo401K.

Sounds like she's ********-savvy.And you've now set a precedent that anytime a tenant threatens legal action, you'll roll over.

I also think it's crazy when people suggest spending unnecessary money to lower tax rate.I will make sure to do as many repairs and improvements under $500 that can be expensed, (the 2% limit rule on the safe harbor won't allow me to do a whole lot more)I don't file Schedule A, so no on the donations, I am not eligible for an HSA, or any retirement contributions.Don't have any dependents, and you cannot rollover non-spouse inherited annuities.

Does that 90 day notice to vacate roll over to me or would I have to give her a new 90 day notice when I assume ownership?

Does that roll over to me when we close escrow?
