Study all strategies, markets, etc, and find what fits your strategies.

When you have a duplex and tenants on both sides stay for ten years, it almost guarantees that something isn't right.I would study your market and determine the value of your rental, because I bet you are losing money every month.

It reminds me of the Charles Schwab study - their best performing retail investment accounts were from dead people that never closed out the account.

Therefore, I have been trying to study up on techniques used to make good offers and over come objections. 

I will start work with EY as an auditor in the fall and have recently begun studying for the CPA exam.  

Do not know much about them, but the Fund of Funds model will be an interesting case study during the next 3-5 years especially as deals go bad and investors look to these sponsors and the level of due diligence they did will be very interesting to see how they handle the lawsuits, as its not an if but a when, regarding a lawsuit.

Now I'm not gonna be Mr Tour-guide for any/all who want to stop out and just look around but if you go through the steps and are serious, we have built out acquisition strategy HECK-YEAH I'm gonna say come-on-out and we'd carve out some time to do market tours together AND I'd equip you to do some self study/exploration. 

But, I don’t think that should be a very high bar for you especially if you are already studying and researching this at 18 years old and you don’t plan to buy anything until 2-3 years from now at the earliest.

Use this time to study at the university and continue to study real estate.

Study the market.
