However, if we are to access that HELOC, the lenders have told us that is using financed money for the down payment.

Im currently looking to purchase a property to buy n hold but I am not sure which is the best way to acquire a rental property in my case.

Your agent will have access to an escalation addendum form assuming they are a member of a local realtor board. 

Currently owner financed and possibly looking to flip that as well.Ps:Was thinking if I should I get my license to have access to the MLS listings or should I just find a good agent to work with?

What's included in this package is connections to lenders and investors, mentors, some sort of boots on the ground in 4 weeks, a expo in Las Vegas and access to tools on their website.

Definitely get title insurance on a property you're acquiring. 

They also require an appraisal(that gets paid to a third party).Other closing costs such as title search fees, recording fees, real estate taxes are costs that you would pay regardless if you acquired the home through a mortgage or HELOC.What consists of the $3500 fee?

Will you acquire the property, fix it up and then decide to rent/flip it?

I see being an agent as a way of accessing the MLS as well as leaning the ins and out of what it takes to purchase and sell homes.

I would look at house hacking by means of acquiring your first property.
