I apologize if I wasn't clear on my question, I didn't really go into my plans for how I would invest as I didn't think it really pertained to my question, yes I know I should not purchase a rental using a HELOC and certainly that wasn't the plan.Whether it be a flip or brrrr, I would use some investment vehicle that would allow me to pay back the money.Roll into as when I purchase my next primary home, use the equity towards the house.The premise of my question was just is owning a home expensive enough now to where it'd be worth putting more money towards it when purchasing to lower payment/pay off quicker, or would it still be worth it to use all of that money towards other real estate. 

The buyer pays all closing costs.

I am looking to pay off some of my other loans that are at higher interest rates so that way I can just have one payment instead of multiple.  

Now, you need to figure out how to find deals and pay for them.

I have every empathy for folks who are hurting especially from instances that are from outside of their control, but filing bankruptcy to get out of debt that she chose to sign up for and promise to pay for the sole purpose of getting ahead faster (her story, not mine) seems less than ethical and Bigger Pockets promoting it is questionable.

Do the tenants typically pay on time or are tenant problems common? 

I'm interested to know how much other house flippers are paying their GC and what type of structure plan they have in place. 

The seller has no agreement with the end buyer therefore cannot take any action to make them pay.

Pay attention to DOM as well as ARV.

Pay who you owe!
