Thats dope. You can still do some good things with 75k in the HELOC. Just remember when you are looking for the rental and crunching numbers that you will need to factor in a monthly payment back on that HELOC. Even with that, you should still be able to find a rental home that you can make money on without having a penny come out of your pocket. Just added monthly income, or use that extra to pay off that HELOC faster so you can purchase another property soon.
Either way, now you have options. Good luck
