So that small of a % is going to be pressed to have that much negative impact on offers.I'd say there are some other equally dynamic factors at work as well.1.

Not so much to "take" his knowledge but to learn from him in that you will still use his services but you want to be able to do some of these things in the future when pressed for time.Most questions can be answered by just asking the person.

They probably know dogs aren't allowed and are pressing the issue.

I'm pressing on though.

He is not staying there or paying utilities so he would be hard pressed to claim it as a second home.Probably nothing will happen if he stops treating the property as a rental by not claiming deductions, but what a can of worms could be opened if it goes back to a rental and he is audited.Remember, no good deed goes unpunished.

Great press!

So subject to does not work for this seller and the second option you propose gets us back to him waiting a long time to get his money.I know he would not sell the property if he didn’t have such pressing need right now.

If you are clearing $662 a month, you are going to be hard pressed to beat that with all the other costs and time it will take to get another property online.
