Is this something I should hire a lawyer/other professional for or can I just do it myself? 

@JerryllYes I completely understand have been a professional data scientist since 2018 before i swapped it out for real estate development 2 years ago.

It’s worth a look see, just do your homework up front before hiring the other professionals to make this happen.Good luck

Your profile mentions that you are an agent with rentals.You would want to see if you are able to claim real estate professional status.If you are able to claim real estate professional status, you can potentially offset the rental losses with your real estate agent income.Furthermore, TN does not have a state income tax allowing you to be more open with your options.Best of luck

This second property is in a MUCH improved neighborhood, which draws in a better class of tenant, it's professionally managed by a trusted company, and it's structurally sound with recent major improvements.WHAT'S NEXT??

Work Quality:I hired professionals to inspect the work, and they found multiple issues and evidence of negligence in the construction.

Thank you for your professional guidance.Sincerely, 

You should look into whether you can hire an officer to walk through your problem unit and have his professional opinion on whether they are smoking in the unit or if it is a residual smell.

And if they are a hobbyist/part-time builder, then they should engage the proper professionals, i.e. a title officer, civil engineer, architect, contractor et al to assist in reviewing the project's feasibility.

New to real estate but possess a deep understanding of the responsibilities to continue to gain knowledge and remain loyal with my clients and professionally with my colleagues.
