(Especially a 2-4 unit.)Do they have friends/relatives/co-workers that would rent rooms from them if they bought a property to show more income?

And, past performance is no guarantee of future results. 

Could you go reinvest it in another property to build even more income?

Income: Verified monthly income must be at least three times the rent (minimum $4,200 combined).

Verifying last 2 years of rental history and income extremely important to find the “best of the worst”.Make sure you understand the Class of properties you are looking at and the corresponding results to expect.

I’d dig into this a bit more.Another assumption that stood out to me as potentially problematic is the 6% income growth and only 3% expense growth.

In Italy your second house or even a duplex section the income is taxed higher.  

I would slow down and think about your BUDGET, what you can get for $30k, and how you can increase your income.

Could you put it on a CC and pay it off within the billing cycle with either your income or selling some stock if absolutely necessary?

@Alec Barnes we use Debt-To-Income Ratio (DTI) instead of income = 3x rent.Reason?
