I'm looking to refinance the property but got denied for a conventional loan due to my credit score not being up to par.

The good thing about Owner Financing is much more negotiable than a conventional loan and is typically approved by the project and not your personal credit. 

Specifically, criminal background checks, credit scores, rental history, etc.

If I were to take this deal since it will barley cash flow if anything is get credit insurance to guarantee me income and use the property for equity growth and a tax write off

The house is in NJ.I  would need to do the background/ criminal and credit check for the new tenant.

Shop around to your local credit unions and small banks.

Great credit, zero non-mortgage debt, only 2 mortgages. 

If you want an FHA or conventional owner-occupier loan, you'll need more than $10k to cover the minimal 3.5-5% deposit for your next $350k primary.While in theory, 2x Equity Lines Of Credit could be approved, remember that Lenders only give out a percentage of the homes' values, so, you may not have $74k of borrowable equity!

However having 100% of the funds in my account 60 days before travel allows me to collect the interest, have access to the funds early thereby allowing me to use it if needed, prevents fraudulent credit card uses since people have 60 days to notice fraudulent activity, and prevents reasonable chargebacks. 

I am currently in college and building credit as well as saving money for a down payment.
