.- you can't roll over Roth IRA money.Speak with @Dmitriy Fomichenko for more details on how to get one going.

Please let me know if there is any prep work to be done on my part as we rollover into next month.

You can fund it with a rollover from any other qualified retirement plan except Roth IRA (IRS doesn't allow that).

I have done a 401K rollover to IRA and use Vanguard.

You should not have purchased a condo where the outside is in bad condition and expect your neighbors to bark and roll over for you.This is a classic example of why I stay away from condos and there is another 20 or 30 more reasons.

What you could do is set up self-directed IRA, perform a direct rollover from your 401k, then you can buy an investment property inside of an IRA.

You could setup your own 401k plan with a company you setup and rollover the funds into that 401k, provided you both are employees of that company, but the funds would still be separate accounts within the 401k. 

Any advice about whether I should take the money out of the rollover IRA from my ex husband's 401k or just borrow from it would be great.

Refinancing or Tax-Free borrowing - When you refinance, you are able to borrow against the appreciation and increased equity of a property tax-free3. 1031 Exchange - A 1031 states that a taxpayer may defer recognition of capital gains and related Federal income tax liability on the exchange of certain types of property, including real estate.This deduction is valuable to investors because you can roll over capital gains from one investment property to the next and avoid being taxed until you sell your property4.
