Can I ask how many properties you have and how long it’s taking you?

Working to systemize this business to run efficiently with future limited supervision to then take the cashflow/profits to continue investing in building our long term rental portfolio as well as invest in other business endeavors.

Take that money (it's all tax free) and use some to buy a small multi-family using conventional or FHA financing. 

Through a hard money lender, but I will take out a DSCR loan in March to refinance.

For example using and LLC to take revenues from properties Etc.

If you do it all above board, you would pay taxes on the rental income received and your daughter would be using post-tax dollars to pay rent which isn't the most efficient.

Or should I create a combination of all three?

If not, all I see is risk with no reward.

You are about to take over someone else's problems.
