Do not allow contractors to manipulate you or tell you how to do your business.

@Mitul Patel ,The market here was hot for buying and selling in 2012-2013 as interest rates were a bit lower and as prices were getting higher.It has now sort of flattened out and become somewhat stable although foreclosures and shortsales are down substantially you can still find some.Other than Phoenix, Tempe is a good choice to invest.

I was thinking of instituting a similar range but my house is well insulated so would maybe keep it from 70-80 Im far from a lawyer but I do not think there is a law governing the temp ranges for STR/MTR. 

Double check that they simply didn't turn the temp up too.How did they find out you were reusing a fridge from the dead guy's apartment?

I would suggest that you either create one yourself or if you buy one, that you manipulate it to make it your own.

A mobile has virtually no wall bay thickness, no attic (slows transfer of ambient temp) and under a mobile is very poorly insulated.

The tenant is simply trying to manipulate the situation to their advantage.This way when you go to court you can show the judge you did not accept the partial payment for rent or as a credit against repairs.

Rumor amongst the gold bugs is that this move will stop price suppression/manipulation.

They have been somewhat manipulative w/me, being a widow, but they have plenty of family around (they took over the daycare from one of their own relatives) who should be able to help them. 

It's a way for people to try to manipulate the system, but let me tell you when you can go online for 30bucks and get some bogus certification it tends to not stand up in court.True services training is normally paid for by non profit for persons with disabilities and can run in the thousands if not more.
