It looks like they only take paypal and Venmo. If its online only and they don't take credit cards it is a scam. You can always charge back a credit card.
I know of several examples of people selling rentals (homes they bought 30+ yrs ago in CA and Seattle area) for $1.5M+ and then buying 2-3 rentals/airbnbs in Coeur d Alene area thru 1031 exchanges (tax free). The gov't has had their grubby hands in it for decades already.
