Proving Income on a STR New Property

[Cameron Fowler]

How can I prove to a bank that a property is going to make money based on projected numbers? I think more specifically is it even possible? My thought process is that I do not have the funds to purchase a house but I have a very high credit score and if proving to a bank that a specific property can produce significant cash flow will persuade the bank to loan me the money. I am more than welcome to other suggestions.
