In Illinois, where I practice, since the porch swing is "hanging" (not screwed into the ceiling)... it would likely not convey, unless the seller agreed to leave it behind.
Not sure how "close" of a friend this is - but it seems a little ridiculous to let a $100-200 (if that) porch swing sour a real estate deal, and create a rift in a friendship...
The key to avoiding problems with this type of activity is knowing what does and doesn't convey and clearly articulating that to the buyer. It's when these things come up after the fact that people become enbattled.
Listing agreements normally outline what does and doesn't convey with the property. In my opinion, most would feel that a porch swing would be considered part of the furnishings and therefore would not convey.
A friendly meeting with your favorite beverage may help you get through this with your friendship still in place.
I agree with Alan May. Most likely it is a chain that is holding up the swing. The swing is personal property and can be taken with if it is hanging on a hook of some sort. If you have to unscrew the swing to remove it then it is a permanent attachment and should stay. Think in terms of drapes and blinds.
It's not worth losing a home you love over a porch swing. Good luck with your sale. Hopefully you'll be in by Christmas!
I would not assume a porch swing is included, unless specifically listed as such
Hope you clarified whether the light fixtures and window treatments are included........... or not!
Here in CO, anything that is permanently attached would convey with the property. In this case, I say it's not attached. If you wanted it, you should have specifically included it. Are you and the seller in disagreement over this? If so, and if there are other more costly items in question, then it might be worth hiring an attorney to mediate. But if it's just a swing, then I wouldn't let this ruin the deal.
