Tax question for a loss on a rental property

[Andrea Coulter]

Hi BP community, I am a small investor from upstate NY. I have 5 rental units, 1 a single family home and 2 two family homes that I rent.

I am Wondering how the math works when calculating a loss on one rental property against a profit on another rental property, Here is my scenario:

Single family home has not paid rent due to COVID and I cannot evict them. It has been a full 12 months I have not received rent. (eviction process was started before COVID happened and then the courts shut down) Tenant now owes me $14,400. Can I claim the full $14,400 as a loss on my taxes? or can I only claim my mortgage interest, taxes, insurance etc. for those 12 months as my loss? 

Additionally, if I show a profit of $5,000 of my other two properties which I would assume to pay about $1,000 in taxes on. is that $1,000 deducted from the $14,400 loss,  meaning I would really not pay any taxes on the $5,000 and would be left with $13,400 in a loss that I could deduct on future years on profit?

Any insight would be helpful!

I am very curious why I am not hearing many people talking about the ban on evictions and the loss of rent?! Is it because it's not really a loss if you have other properties and can get the tax deduction for future years? I have no hope in ever getting any money from the tenant, they are completely taking advantage of me and the COVID situation. hoping there is some other way to get that money back from the government.
