I plan to use a HELOC but would be interested in the thoughts of others in BPs on this approach or recommendations if there are other ways to financing that I should consider.

@Jacob HavlovickBigger Pockets is a great place to find a real estate tax accountant.A good real estate accountant can save you thousands of dollars by leveraging entity selection and formation, tax deductions, cost segregations, bonus depreciation and tax planning.I recommend finding an accountant who specializes in real estate taxation, business taxation, financial planning and tax planning.You may want to consider working with your accountant remotely to expand your options.I would also recommend looking for a accountant willing to work with you throughout the year.

You have a solid plan and it's working great!
