@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.

Also, for those whose BUSINESS (as opposed to just investment) is STR, they can scale successfully while their experience and knowledge of the industry may allow them the opportunity to uncover and recognize those few opportunities that will provide a much higher than market risk adjusted ROI.

Of these professional wholesalers, nearly all of them will be well capitalized professional real estate investors or large businesses doing hundreds of deals annually with many years in and around every part of the real estate investment journey.

We're probably not going to take the risk if we're busy agents to play that game. 

Is the mid term rental business that you have a 'rental arbitrage' business?

You can check with the Better Business Bureau (BBB), your state’s department of business oversight, or your local real estate community.5.

A strong business foundation ensures long-term success.
