Can I just terminate their lease with proper warning?

Moisture problems can often be solved by drainage improvement, proper foundation sealing, and ventilation.

If you don't have any credit yet (car loan, credit card, etc) a good place to start is getting a secured credit card with your bank, which should help you start building a credit report and score.

Thanks Tyler, at this point I have more time then money, the company that wants to school us, wants us to use credit cards to pay them and buy a property. 

So a lot of duplex’s and even some apartments are really run down, giving the investor more opportunity to raise rents if it’s rehab’d properly.

They also keep saying how they dont want me buying a property out of state because i don't have a network of contractors they trust, and will constantly have to check in to make sure the job has been done properly. 

However you can reduce the risk to almost nothing with proper knowledge. 

Just make sure you're properly insured and leave it at that.  

I'm not sure how to properly valuate this... even though the comps show that the price is correct-ishHow can you help?

For qualification they include usually minimum payments on credit cards etc not the principal.If you're really low income, maybe it's better to find a lender who does "stated income" but there need to be proof: bank statement etc.I'd try another loan officer, maybe mortgage broker who would search for different options.Take a look at the topics here: there were explanations how Rental income would count and @Chris Mason even referred the source where to get the info first hand
