@Yael DoronHi - I don't invest in Phoenix but was just curious if you already own real estate and are looking to expand into Phoenix, or are brand new.

@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.

A home equity loan seems like a possible way to expand my portfolio, would consider buying a multifamily and renting out our current home to live in one of the units and purchase it as a primary home (assuming its 4 units or less), but being in the Santa Cruz CA area, I am afraid I'll need to look outside of CA for any deal that makes sense, and can't afford to lose my great job (can't work remotely).

It helps me build connections with other investors, and it helps me expand my network of capital partners.
