Selling a house, need advice

[cookderosa]

After 10 months on the market I finally got an offer on my NJ house. The offer was low and we negotiated up to a semi mid point. Now we are running into all kinds of roadblocks. This is the 1st house we have ever sold, we bought it new 31 years ago. In ~1985 we added a wood stove, in ~1988 we added sky lights and finished the upstairs ( a cape) ~ 2009 we had the roof replaced and in 2004 we had fire damage repaired. We applied for and got permits for all but the roof. Now our buyer wants copies of those permits, we do not have them, we told him he could request them from the town but his lawyer only requested the town look back 10 years so of course there weren't any permits. We do still have some of the interim approval stickers hanging on the studs in the attic upstairs and the electric approval sticker is on the fuse box. Are we being difficult by saying if you want more proof you pay to ask the town if they even have records back over 25 years.

Also the NJ recommended Radon level is 4 we tested at 5.1 so he wants radon remediation. As scientist we feel the margin of error covers this. The test was done in a closed off house in the back corner of an unfinished basement. We did get 2 quotes and they are around $1700 we offered $700 toward him getting it done later. We lived there and raised 3 children there my radon remediation was leave a basement window open a little, it is a lot cheaper than paying for remediation and then the electric cost of running that system plus maintenance on the system. If we/he ever finishes the basement it will probably be easier to install remediation then.

We did also have a list of several items they wanted done after their inspection. We agreed to most and some we didn't really have to do. The closing is not for a couple of weeks and we have not finished everything yet but he was planning on going to see the house tomorrow to check if things were done yet.

I respect the opinions of the people here and hope you can tell me if this is just normal closing stuff, are we being unreasonable or is the guy being difficult.
