.- I have some properties under my name as sole proprietorship, one under a single member LLC (disregarded entities in Pa) and I am separately an independent contractor (real estate agent since I retired last year).

Is a single member llc reporting on schedule E (disregarded entity) eligible?  

If you’ve received notices for increases, please disregard and pay your previous months rental rate. 2) RENT DISCOUNTS: In the hopes of helping tenants during these trying times, any tenant(s) who pay their total rent balance in full by April 7th will receive a 10% discount on total rent amount as well as discounts on payments on any outstanding balances.

We have had a fully booked month in March and April until airbnb emailed our guests to let them know they could disregard our refund policy and cancel without penalty.

I would disregard age of the property, and focus on location, deal, structural problems if any, and whether wiring, plumbing etc are up to code or insurable.Houses built before 1978 have to be rented with a disclosure (and brochure) about lead based paint and the terrifying ramifications of licking the walls.

And I assume it would be a disregarded LLC?

No good deed goes unpunished as they say, hopefully you won't have to learn the lessons I've learned, but continuing to disregard advice is a great way to accomplish that.

Disregarding state and local gov't actions, it looks like the federal 'stimulus' bill that just passed only applies to federal backed loans.

for example let’s say you owned a rental property in an LLC taxed as a disregarded entity and your profit after all expenses such as maintenance, debt and taxes was $100k and your personal tax rate was 30% 1) Would You pay 30% on that $100k as taxes so $30k and the remaining $70k is yours to keep with no further taxes? 

This will provide a tax benefit even to those who do not itemize.For the 2020 tax year, a taxpayer can elect to disregard the 50% AGI limitation on deductible contributions.
