I proved to them lending me their money was an easy way for them to profit themselves.

It’s about proving you can return their investment.

Unless someone can prove otherwise, I’m fairly certain I was just scammed out of $3,400 by a supposed “Lead Provider.”

I've heard that some people have used a trust account or something similar as a method of income, if you can prove history of payments and continuation of these payments.

You have to prove you did everything right and then because of “empathy” for the poor snook who “fell into you schemes” you may lose anyway.This is a legally binding transaction that will be treated that way by the law.

Can they prove how long it takes to rent a vacant property?

Study the market.

I've been self-employed for only 6 months, and loans are proving difficult to come by despite my great credit (not to brag, I'm moreso frustrated and seeking help).

I would stay away from this, unless you have an empire and can substantially prove it.

I have been studying for my real estate exam, and am excited to pass it in February.
