Earlier quoted context omitted.
Renting anything really isn't a bad move. There's not much upside to owning something that depreciates in value. Instead of buying a sofa for 2000$ renting one for 50 and putting the rest of your money into some productive financial asset is actually perfectly reasonable.
After 4 years you paid for the sofa 2400$, "rest of your money" is -400$, sofa doesn't belong to you, and in case of scummy renter you own money for damage repairs and cleaning. Ready for legal litigation?
$2000 is a lot for a sofa, and if I understand correctly is what people spend if they want a sofa for a long time and not just a cheap IKEA sofa to throw out after the dog / kids ruin it in 2 years. If someone’s spending this much on a sofa, I hope they expect to keep it 10 years and should be buying not making payments!
