It was on market for over 150+ days since Nov 2019 so the price was reduced from its original $115k.

As real estate is a business would this reduce my tax liability on the regular job?

NOL can be used at the end of that time frame to reduce tax liability.  

Sometimes I don’t have the energy to do not even one hour of projects.

You reduced rents substantially, did you not?

Keep a cash cushion because you never know when you might need it for something bad or an amazing deal comes along you want to jump on. find your WHY and use that energy to push you EVERYDAY.

Now those tenants will be hard pressed to make it with reduced sales.

But unless you're actually interested in the work a Realtor does and are willing to dedicate a lot of time and energy into creating a sustainable business, I would not bother to get licensed.

However, I personally don't expect it to be any time soon given that they have recently announced they have STOPPED charging in some of the states they were previously charging in, and REDUCED their fees by 50% in other states due to COVID-19. 

What is a good approach and strategy to ask my landlord to reduce rent?
