Is it advisable to do that for protection and tax deductions?

Talk to your insurance company - depending on your deductible and potential increase in future insurance you may or may not want to put in your own claim.I would also probably consider cutting my losses and getting rid of the tenant asap.

You must also materially participate in your RE activities.If you materially participate in each RE activity, losses are fully deductible.

I would contact your bank and make sure they no longer allow for it to be deducted. 

Meeting these requirements could allow you to offset W-2 income with deductions like bonus depreciation and cost segregation.

.- Once it looks like you are going to clear $50k for the year - after everything is deducted!

Any fees collected by the property manager should be a separate charge and not deducted from rent.

Yes, it is your debt to pay, the title co. just didn't catch it, and deduct it from your proceeds.

But, your refinance is not always tax deductible. 

You do not need the property to be in an LLC or business entity to be able to take deductions, write offs, etc.
