But they said they still have fleas.At this point, I feel like it is fairly safe to say that they brought the fleas in with them or at least their cleaning habits (or lack thereof) have contributed to the problem.Anyway, my question is who is ultimately responsible in this case? 

I am building capitol to flip myself and think it makes more sense to make sure you can have as clean an inspection as possible.

They are now clean, according to their Instagram, or Twitter, or whatever.What goes through your mind, and how does it play into your overall evaluation?

You can attempt to verify all of this by contacting the providers (water/gas/electric, insurance company, HOA representatives, etc.).Also, make sure you have a couple of potential buyers lined up. 

***DISCLAIMER*** I Own & operate a cleaning business.

Laundry leased assets in closet nets 220/yr.Individually metered electric (heaters), no HVAC (standard for that area and age unit), but building utilities run 5k/yr - probably business utilities not being paid - unsure.

It sounds low, especially if you need to do major plumbing and electrical for the work you are describing. 

IF POS is unconstitutional, then you could also say that any inspection is also unconstitutional; electrical, plumbing, etc.

We did one..we bought the home next door & initially we got $820/mo in a 70's era SFH in very very tired shape.When they moved after 5 years we rehabbed it for $18k & got $1400/mo & that was 6 years ago.We did bump the rents over 2 more tenants (now $1650/mo) but the current tenants do all the maintenance.When the 20 yr old HW tank burst at the seams they shut everything of, cleaned up the mess.
