That said, a lot of that credit has to go to myself (at risk of sounding conceded) as I personally had to show and deliver the drive and determination it takes to come this far.

That is if they decide to contest the charge, you don't concede and they take you to court.  

I also have fought several other appraisals and won them by proving to the appraiser that there were better comps in the area - sometimes they will concede, sometimes they won't. 

No, you do not have to concede to the tenants request to go into month to month. 

They usually come in about half that as long as they don't need all the windows and exterior doors replaced, but they can cost that much, so use that in your negotiations, that way even if the seller concedes to cover half, you might still get it all paid for. 

@Tegan Lehman  While I concede my suggestion sounds a bit snarky, that wasn't my intent. 

Then you conceded having a partnership.But what if you keep it more casual and less committed?

The seller also conceded almost $5000 in repairs after the inspections due to some undisclosed safety issues with the electrical and plumbing.

Once again, I’m not a lawyer and if this went to court the magistrates could go either way...But it sounds like they conceded that money to you by their own choice.

They conceded and I don't pay for that crap anymore.
