Not sure of the advantages of buying under the LLC will be when you can most likely get a more favorable loan product and lower interest rate with a personal mortgage rather than what will be a commercial loan under the LLC.I'd suggest picking up a househack 2-4 unit property; you all can live in 1 unit and rent out the remaining.

*The condos are seller financed 1 of them is a two year balloon period with about a year remaining and the second is a 5 year balloon with 4 remaining.  2) Did you buy the properties under market value?

You can do this without a time restriction but you will leave equity tied up in property.I personally would wait for the 6 months unless you needed the cash right away.

I’ve considered the possibility of purchasing the house for cash and doing seller financing to my brother, but that ties of a bunch of money for a long time. 

If you invest in a syndication as an individual that is organized as an LLC, and you are a limited partner (LP) the stake you are taking in the LLC is already its' own measure of asset protection since you are limited from most forms of liability tied to the LLC.

Maybe the son has a record or they can tie this to some other known event.

Our goals are to move the remaining POH we have to TOH.  

Property is located in Boulder County, Colorado.Current value: $545,000Current remaining mortgage balance: $335,000 (Myself and my partner and both on the title and mortgage in our personal names)Bank: Local credit union (the same bank that holds the first mortgage on this property)Background: My partner still lives in the duplex as his primary residence.

I would use the remaining $30k to add to other funds saved up and invest in another property. 

You become responsible for mortgage payments on the remaining balance).
