Please note, I don't need money at the moment and don't have any other investment vehicles that will generate a guaranteed 8-10% growth to my investment.

This is why I love real estate, no other investment vehicle that I know of that allows you to eliminate unavoidable expenses while still making money. 

Continue to invest in both vehicles. 

After hearing that my 90-year-old grandfather, who now relies on a motor scooter most days to get around, just returned from a trip to obtain continuing education in order to his civil engineering license active, I realized how silly the excuses we create for ourselves truly are...If he still has that kind of fire at 90, how much should I have today in my 20's!

I love being a private lender but the fact that it simply increases my taxable income makes me consider shifting some of my note portfolio to multi-family perhaps...You might find this discussion beneficial where similar question is raised: https://www.biggerpockets.com/forums/51/topics/604...Owning notes in your retirement account (especially self-directed Roth IRA or Roth Solo 401k) is ideal since you can have tax-free income for the rest of your life if you utilize one of these vehicles. 

I currently live in the State of VA and property tax is huge on vehicles.

Make sure the vehicle you choose is able to qualify for lending.

Establishing an investment vehicle can hedge against this and set out an enforceable legal structure to govern the investment and its management.ZachThis post is intended to convey general information only and not to provide legal advice or opinions.

I used part of it to pay off both my vehicles and was thinking of using the rest as a down payment for my next property.

Merely putting a vehicle in the name of an LLC doesn't constitute a business expense.
