FAR contracts directly address this situation.

I got my first list of 300 addresses.

However, that's not completely addressing the problem.

If you can find a deal and enough money to purchase before you turn 18, you may be able to get it with a trust then have the trust turned over to you when you are 18.

Even if you have to pay for it, it should be looked at by an official, maybe with the subject city inspector or a referral from someone you trust about the environmental question.  

Trust your gut.

I do have to point out I am weary about buying systems and I typically don't invest with those I do not trust, or ones that at least don't have a money back guarantee.

@Felicia Richardson I basically just found neighborhoods with duplexes that I felt matched my criteria (safe, in reasonable shape, strong rents in areas that were either growing or would remain stable), used Zillow/Google Maps to help get the addresses for all duplexes those neighborhoods, and then typed the addresses into the county assessors website (not sure if your county will have a site that allows you to search properties by address, but ours does).

Don't trust them no matter how long they have been with you.2.

You can google their web address.
