I don't know where the source of the data would come from though?

I recently became a father, own a mortgage, and am currently the sole provider for my family.

My view is that one should hold their seller financed notes as a source of income.  

Buyer has examined the Premises and is relying solely upon such examination with respect to the condition, character and size of the land, improvements and fixtures, if any, constituting the Premises.At Buyer's own cost and expense, Buyer shall obtain and maintain in full force and effect at all times during the continuance of this Contract: (a) comprehensive liability insurance for bodily injury or death to any person or persons, and property damage insurance, in such amounts as Seller reasonably deems necessary; and (b) fire and extended coverage insurance in an amount sufficient to prevent Seller from being a co-insured under said policy of insurance, but in no event less than the unpaid balance due under this Contract.Seller and Buyer shall both be named as insured parties in the insurance policies required above, as their interests appear, Buyer shall furnish Seller with memorandum copies of such insurance policies upon Seller's execution of this Contract.

I want to purchase my first property this year and hopefully purchase one every year to also create a passive income source for my family and me.

In addition, I’m interested in learning from investors how to decisively evaluate cash-flow and appreciation deals, sources of financing and creative financing or sweat equity relationships so that I can start investing in the future.

Obviously the very source you quote does not agree with you.
