I almost feel like its more unusual when people DO change their car registration to the new state, lol. 

How far do i bend before I'm doing myself a disservice? 

@Cheryl C.Not as unusual a story as you might expect.1. 

I am trying to stick to “making you numbers work” but starting to think I should bend some.

run a load calculation on the house to determine size of unitbut you also need to look at the air flow going to the 3rd floor and where it's coming from If it's coming from basement 3 floors is a long way to push air going upNot going to do any good to increase size of unit and duct work won't handle itThe more bends in duct the more restrictions If you get enough air to cool it there will be way to much to heat itFlat roof doesn't give you many optionsHate to say it but window unit might be an option

How do you estimate for an unusually hot summer or a colder than normal winter?) 

It isn't that unusual for property managers to do an inspection with new tenants. 

Then, next time, you will not have to have the conversation - simply refer to that provision in the lease and reiterate that is what the policy is.Unless the ceilings are unusually high, they should be able to figure this kind of thing out so you can move on with your life.

One of his best unusual deductions cited.....A girlfriend:The owner of several rental properties hired his live-in girlfriend to manage them.

Also something to keep in mind about google voice; I live in the Los Angeles area and have two vacancies available that were getting unusually high levels of attention online so what does google voice do?
