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 specializing in real estate taxation, business taxation, financial planning and tax planning.Consider working with your accountant remotely to expand your options.I would also recommend looking for an accountant willing to work with you throughout the year.

If the tenant complains there is no heat, you should respond.

The rehab took 5 months and I did 90% of the work myself, saving $30k but losing a lot of time.

Glad I'm working the New Hampshire market!
