I had one of those back pressure sewer valves put in $500 installed.It made a BIG difference as the insurance co didn't want to include coverage as the home had a claim in the past (b4 I owned it, & the city sewer backup was not the fault of the home owner).In my area if it happens you're responsible for the temp accommodation of the tenant(s) until it's cleaned up.Since then the only blockage we had was viewed via camera & found to be a city clay sewer pipe collapse.

If the tenant requests a larger font, we will accommodate.

I have followed every landlord rule known to man, have bent over backwards to accommodate them and have simply given them too long of a leash.

These do not include any additional revenue from the sale of car condos on-site or overnight accommodations nor the two major event organizers (Formula E & Formula Drift) who have welcomed discussions on having an event at the facility should I manage to wrap things up.My plan and the area I need help: I believe the facility could be purchased for $2.75M (which is roughly 13x the 2014 EBITDA).

I'll accommodate them but I'm not going to do it for them. 

Typically a disabled tenant is able to make modifications to the property to accommodate their disability.

Sounds like you are trying to accommodate his needs by bending your rules.  

According to a Nevada attorney 'The federal Fair Housing Act also prohibits discrimination in housing accommodations against those who use service animals. 

Anyone who wants you to invest with them but can't accommodate a visit isn't worth your time – MAKE SURE you're getting what you pay for.

Have reserves and get yourself a great property management team that has more than enough hired staff to accommodate for the addition of your properties into their management portfolio.
