Long Term Rental.Please feel free to reach out in my dms - I'll need property address along with your debt / equity/ monthly payment information!

Used your HELOC to fund the down payment on a second property if the right opportunity presents, otherwise those returns wouldn’t be juicy enough for me to take on more debt for the sake of scaling if you’re buying at retail.
