The home we bought was being renovated for my daughter as her principal residence.

You will need to know the current principal balance, the amount of money needed to bring the loan current, the amount of rehab the property might need, the monthly mortgage payment amount, and the potential ARV of the property.  

Roth IRA principal can be withdrawn tax and penalty free....just not the earnings.  401(k) loans are similarly allowed and not taxed or penalized. 

Here's my thinking:In a higher appreciation area, I still want to see cashflow from day one to limit risk, but the total returns are more influenced by appreciation, associated rent increases and higher property values (which result in larger mortgage principal reduction and higher tax depreciation).  

I have a tenant of about 3 years in my lowest performing property in Maple Valley that has not gone up in value for 3 years and although rents are good/solid cash flow and principal pay down ($500 a month CF, $385 a month PP), the HOA is driving me nuts and I’m looking to sell and take the 200K equity left after transaction costs and re-leverage into other properties, such as two SFR’s.The longer I wait the worse things get for me.

And this is my PRIMARY question, given the abovementioned context.. if we later decide we want to keep the rental but want to get the principal out of RETIREMENT PARTNERS LLC to use on other investment, could we sell the property from the RETIREMENT PARTNERS LLC (which has my IRA as 50% owner) to yet another MMLLC called FINAL DESTINATION, LLC where he and I (and maybe others) would be personal owners (i.e. no IRAs involved)?

So- If I was the principal I would look at a few things.

E&o typically does not cover an agent when they are a principal to a transaction, and I think there is a good possibility liability could be created by the actions of a spouse.
