This being your first deal makes it a gamble but if you're really able to get the building at that price you can borrow hard money for the purchase and renovation.

Lastly, if you are still worried, moving forward write your rental criteria on paper, make sure it follows fair housing laws; go get it notarized and stick to it, the next time this happens and you deny someone for the reasons on your criteria you can clearly point out in court that your criteria was well established before they even ever came in the picture.
