@Troy Ramey made some excellent points, I would also add that you should look into the 3% down payment conventional loan options, as they are typically much better loans for people with decent credit than FHA loans are.

From reading books like Rich Dad Poor Dad, and other RE investing books, taking online classes and courses, going to meet-up groups.

I am aware of credit cards but hard money and gap money lenders both require the same thing.

Allegedly she is "loaded", has great credit, and owns a number of properties out of state.

My concerns are I am currently working on my credit (low 600 Fico), I have limited savings and the house is in need of renovations to bring it up to date.

Zelle is easy and is credited to your account immediately  

Also if selling the note wouldn't the note buyer want to know the credit information of the seller since they are repurchasing the property back after 3 years? 

I do not look at credit score, because many of my best tenants have poor credit ratings, due to poor money management but they understand they will be on the street if they do not pay their rent.  

@Adam H.Mortgage is off as this is a line of credit not a mortgage.

While in the process of finding contractors and meeting people, I learned about historic renovation tax credits.
