Possible Rental Scam, but Unsure: Requesting Help

So, I am looking to rent an apartment and I think this is a scam, but I’m unsure so I want a second pair of eyes, if possible.

I found this apartment in Washington, DC on apartments(dot)com and zillow. I submitted the interest form and heard back from the owner of the property, who lives in Spain. He stated he will utilize Keller Williams as a third party company to show me the property and facilitate the rental documents, key transfer, etc.

This all sounds normal, but here’s where it gets weird: I received an email from KW today– at least I think. The email is not a US email, but a Spain one. In the email is a document laying out the owner’s details, property details, etc– but no tentative lease agreement or fee schedule. KW is also stating that I must provide a deposit (first month’s rent and a holding deposit) before I can inspect the property with them. If I inspect and decide not to lease, they will allegedly provide a « full refund.

This sounds like a scam, but I just want to make sure I’m not crazy.
