It's not just leaky toilets, but stuff like giving relationship therapy to tenants who are boyfriend and girlfriend so that they don't break up, causing one of them to break their lease, etc. 

I've been managing a strip mall for almost 2 years and the tenants keep asking me to fix or replace their lights, heaters, toilets, ceiling tiles, etc. 

That said I do have an older wagon-style compact vehicle with an already-tired interior which can carry 5 toilets at once (ask me how I know) or a few doors or a few full 8' sticks of lumber at a time.   

I don't know anywhere where they won't care about an unpermitted bathroom...toilet, shower, sink...the plumbing, the electrical circuits?

I recently completed finishing work, lighting installation, toilet replacement, final cleaning for listing pics, and sub'd out a water heater replacement with a professional plumbing contractor friend of mine.

Most long-term tenants don't require assistance more than a few times a year, say for a running toilet or help to reset the thermostat.

This is the simplest method, but it also means your tenants are more likely to abuse the utilities by leaving windows open with the heat or A/C running, leaving lights on, ignoring the toilet that constantly flushes on its own, etc.3.

Put another way, I don't like to purchase a property with terms and conditions that may not pan out such as purchasing with cash, or purchase with seller financing and then have to worry about whether or not something won't happen where I cannot get the financing down the road that I hoped to get, or can't make a balloon payment because some unpredicted factor stopped me from getting an expected loan, or I had to used the money I needed for an emergency.

This is the simplest method, but it also means your tenants are more likely to abuse the utilities by leaving windows open with the heat or A/C running, leaving lights on, ignoring the toilet that constantly flushes on its own, etc.3.

It's basically the same thing, but in the second scenario, you arent sharing a toilet.
