It’s not uncommon to see a lot of grand claims in listings. Usually, they’re not demonstrably false. However, you do need to be careful if you want them to be true. If the seller has said that the property was completely gutted, then you might want to get a warranty in the agreement that they confirm that. If they seller says that the pool is beautiful and everything works great, then get them to warrant it. If something in the listing matters to you, get it in writing.
