Good for you for creating a win-win situation! 

I think if you set up a brokerage account with the same bank that your business checking account for the LLC is at, you can simply move the money from the checking account into the brokerage account and then purchase something. like USFR, which pays 5.4% in T bills with zero risk of loss or BKN which pays 5.7% in tax free Municipal bonds if able to tolerate some risk (this gives me a >9% tax effective rate on my cash).

Win - win all around.

Simply let them know of the error and that you'll be returning the "extra" portion now or when they leave (should they need an extra day or so). 

For SB1079, a prospective owner-occupant can bid on the property post-sale and win the auction within a 45-day period.

Watch local home prices and how they go up to win big over time.Good luck!

I could've lent the money out or invested in notes, but I'm more interested right now in asset accumulation.I ended up simply rolling my SDIRA into my current 401k and taking a loan against that, thereby being able to utilize almost 100% of those funds (not quite at $100k in the 401k, but close) and purchase a duplex with a conventional 30 year loan.If I had $150k or more in my SDIRA I would have looked at other options, but with only $50k I found the path I chose to make the most sense.

If you're okay with less returns but lower risk/work, you can simply cash out refinance now without doing any work since it's rentable.

All of that's great, but at your age, the biggest benefit more than any specific strategy is simply ... time.

To make a lot of money as a PM, I think you've got to make compromises that I'm simply not willing to make.
