Quote from @Brian Dela Cruz: Data entry clerks - likely to miss deductions, overlook credits, miss carryforwards, make mistakes on tax law limitationsCPA - get it right, reduces errors, and helps you in building your wealth through tax savingsWhat are your thoughts?

If you spend the entire $300k restoring the property, then here is the end result:- deductible casualty loss of $50k- no current tax- the restored property has $0 basis and cannot be depreciated- when it is later sold, the entire sale price is taxableMechanics and reporting are tricky, and I would not recommend to DIY it, especially since my scenario is over-simplified, and your real scenario is likely to involve more gotchas.Thanks so much.
