Build multiple income streams that are resistant to pandemics. 

Personally, if you told them about the inspections prior to move in, they already know what to expect and if they are now trying to resist....that would be a problem for me.

Get something with a 12 mil wearlayer WITH A SCRATCH RESISTANT FINISH like Aluminum Oxide.

Ozone (O3, made from O2) smells like a copy machine in a closet and will corrode (oxidate) any organic molecule by attaching the spare oxigen to it.

But if the tenant is resistant, tell them they have to permit the inspection as long as you have provided proper notice.

He's apparently been using the same test for lead based paint for years.Sorry, couldn't resist...

  $50.00 less per month over 12 months works out to $600.00.Also, hind sight being 20 - 20, you might have met less resistance if you tried to bump them 8% each year. 

@Joshua Norwood have you brought this up and faced resistance? 

There is a good chance this tenant will resist moving - and may use every trick in the book to delay that at your expense - because they are getting such a screaming deal at your property.You are wise to systemetize your rent collection.
