I am selling my primary residence, and have come into what I feel is a somewhat odd situation.  My wife and I listed last week, the home is over-improved for the area, so we knew we may get a lot of activity.  We actually received our first (and so far only) offer of $14,000 over asking, the very next day!  We are trying to decide if this is a sketchy tactic on the buyers end, because we don't think it will appraise at that price, or we would have listed it at that.  They also wanted us to pay their closing costs and cover a 1yr home warranty, which was supposed to tally at $4500.

They were also very aggressive on wanting us to accept literally within an hour or two, as my agent didn't call us until later that evening, or the deal would be off.  Plus, only the husband had seen it in person, the wife "saw" it only through Facetime.   We thought that was odd as well, to make that kind of offer without both seeing it.

Are we right to find this suspicious?  We feel that they are trying to woo us by throwing this high offer at us (even knowing they were the only offer), and then planning on playing us when the appraisal came back probably a bit lower then our asking, their bank not lending them what they "want", and then expecting us to accept a lower number (essentially our asking price) from them because we will have been weeks into the process at that point and not want to go back on the market?

Are we right to see the appraisal and lending process go like that?

I am speaking in the past tense because we didn't think this felt right without the wife not seeing the house as well, they supposedly got offended we weren't jumping at the high offer, and pulled it.  A day or two later, they let our agent know that they wanted to see it again with the wife, which was today.  We have not yet heard if there will be a new offer.  To be honest, we aren't sure if we even want to deal with these people even if they come back with something closer to asking.  Or are we overthinking this?  Thanks for the help!
