How could this deal turn out to be a scam?

[Marian Smith]

Unsolicited phone call offering to buy a condo I own 500 miles away in Texas panhandle. Price is probably above market, 17k down finance 75k @ 3.8% 35 yr amortization. 3 year balloon. Also offered cash at 30k less. Tenant occupied through Nov. 2023. Buyer is a newly formed LLC out of Houston, so even farther away. Is this just someone betting big on inflation? I know cold calling is how a lot of investors buy but how could this go bad? using a TREC 1-4 contract so hard to scam there. I am leery because it is such a small deal…just 1 small 1 bedroom unit…and not a great a deal unless maybe you are local and have a use for it…walk to community college. Condo bylaws prevent airbnb usage, so not that. Thanks for any insight…just feels too good to be true.
