Wait until you are sure it won't close by the deadline then extend...you aren't being unreasonable and they aren't going to want to go back on the market around new years.

That being said, if it is going to take longer, I find it really unreasonable to expect a tenant to deal with unfinished floors in their bedroom for more than a day or two and even then I would probably put them in a hotel or at least prorate their rent. 

Is this an unreasonable approach? 

Don't be selfish and unreasonable.

It's actually $150, which is more than 10%, which is probably more on the unreasonable side. 

You can find list of Fulton county ordinances here https://library.municode.com/g... under section 14 Once you are able to find the ordinance then read through the same thing cuz it may clear some doubt or cause additional ambiguity I would then contact an attorney to draft an email to the city if you feel that you are being charged unreasonably.

I understand that the property is only worth what the market is willing to pay and that if I price it unreasonably, then it will sit forever.

That's very unreasonable, IMHO, to just get a document signed and notarized, and get it and the original deed of trust back to me.

So, financially it would be unreasonable.

  $2.2 million rent is on the higher side, but not unreasonable.
