EIN needed not just if you hire employees but to open checking account as well.

Some don't want anyone there, some don't care, most won't want to spend time listening to your justifications of comps or values.

However, I'm not sure what your justification for eviction would be if you do file for this since your lease does not specifically prohibit window units. 

Volcker made clear his disagreement with this 2% target, writing of it in 2018, “I know of no theoretical justification. … The real danger comes from encouraging or inadvertently tolerating rising inflation.”The classic monetary theorist Irving Fisher had warned, “Irredeemable paper money has almost invariably proved a curse to the country employing it.”

Again, acknowledge their normal human reaction, and explain your justification for the increase: likely comparable market rates, and a discount off that for their positive performance to date.

I am just if you are open minded to a traditional rental or just student rentals.  

I'm getting the impression that making a lower offer is not necessarily standard practice for Turnkeys, but that I could make a lower offer if I had good justification for why I thought the sticker price is too high.  

@Amy Engelhard, never get sucked into the "that'd be a steal where I live"-type justification.

And, on a side note, some of these items like electrical and repairing the aluminum siding aren't going to really be justifications for a rent increase.  

Can't speak for others, but that's a perfectly reasonable justification to me.
