I would definitely not proceed with purchase unless you've had a thorough home inspection done by an independent ASHI certified inspector. It may cost you a couple hundred but save thousands.

For some reason I can't add photos. I attach it and it doesn't appear.

If dirt isn't tainted with chemicals or petroleum products, it shouldn't be an issue. Dirt floors do allow significant moisture to be released into the air, even if it seems dry. It's usually a good idea to put down a vapor barrier like 6 mil polyethylene and cover with gravel, pavers or concrete. I've even seen pallets used to keep it down. Walking on polyethylene is slippery and will eventually ruin it.

The floor is concrete! I'm having a hard time explaining where the dirt is without a picture. Houzz won't let me attach pictures right now. As you go down the steps, to the left and right t has no walls on either side, just exposed dirt from when they dug out the basement I guess?

We too had a dirt basement with concrete floor. I’ll attach pics of our solution.

Sorry. Can’t attach!

We had a 5 ft block wall installed which we painted white with masonry paint. Also had vapor guard laid on the dirt with pegs to keep in place. We used small rods to secure the ceiling insulation. Our home was built in 1940 and the basement stays very dry with even temperatures. We have a radon detector w no problems. I just wanted a better look for it. As more info, my grandmother’s home, built in the 1800s and still in use, also had a dirt basement. So I don’t think it’s an immediate sign of trouble!

your pictures may be too large or wrong format. Take a screenshot from your phone. They're usually the right size and file type.

It will be difficult, but I think you can get some poly to cover that. Worry about it after you close on the house. Could that have been an old porch or addition?
