It seems OP does not have genuine concern for the wellbeing of the deported. That's alright, we don't have to be close friends of everyone. But let's not try to act like we are close friends just to inherit the furniture, as some answers here suggest. That's underhanded, deceptive and once the target person recognizes this, they will certainly be very disappointed or angry.
I would ask the person directly, something like:
Hey, I hear you are forced to leave the country. I'm sorry this is happening to you. If it helps at all, I've long searched for furniture, and since yours may be left behind, I feel we could both benefit if you decide to sell it to me. I would also like to help you with moving in return.
- Being sorry is a mere display of basic empathy. It is not underhanded.
- The benefit is clear: They do not have to worry about getting rid of the furniture, so that can be helpful.
- Offering some additional help is a guesture that shows you are not preying on defenseless panicking victims, but are willing to do a fair trade.
I've been in more or less similar situations and have experienced both approaches. Tho the reasoning above should provide more plausibility. In my experience, just stating, in a friendly manner, your intention is virtually always better.
I grew up in Germany, but I believe that it is possible to be both polite and direct.
