You need to go back and retrace your steps: they didn't send you requested paperwork "in time".

I've actually noticed we've had tenants that had given notice to move or their lease was coming up and they have actually decided to either stay or request an extension with everything going on in this area.

What property managers do can be a lengthy list, but from a 30,000 foot view they oversee the properties and the tenants and handle the day-to-day maintenance requests, resolve tenant issues/disputes, collect rent, enforce late fees, help you through eviction process, market the property, etc. 

I have written to all of my Senators and Congressional Representatives requesting that they require all commercial lenders with government-backed commercial loans (Fannie Mae, Freddie Mac and HUD) to defer commercial mortgage payments for the same duration as tenant evictions are stayed, with all deferred mortgage payments to be automatically added to the loan term - no modification. extension or balloon payment needed.

As an experienced investor, do you still request for a home warranty or would you say this is more for beginners and those just getting started out in real estate?

It's not about the cheapest but what you get for what you pay and all insurers and policies are not created equal.If insurance won't work many landlords are responding to letters from tenants requesting rent abatement to first apply for the PPP and other SBA loans as they might cover some of the rents.

You can really only go to a local bank or credit union if your income and DTI supports the loan requests as they calculate global borrower financials (I know this because this is what I do for a living).

You can also contact your lender and request another appraiser.  

I even requested if I could increase the interest rate, I just simply did not want to lose this deal.
