Answer
(Fatwa: 1217/1157=B/1430)
Whatever your neighbour has entrusted you is amanah (trust). He allowed you to use the bed and washing machine, so you can take them in your personal use; it is unlawful to give someone else for use. If you want to return to your country, give the things to any reliable friend of you who can return them to their owner. If it is not possible, lock them in your house safely and return to your country. If it is also not possible, sell them and preserve the money:
وإذا دفع المودع عند موتہ الودیعۃ إلی جار لہ ولیس بحضرتہ عند الوفاۃ أحد من في عیالہ فلا ضمان علیہ (4:375)
In future, you should avoid receiving trust in this way. Or take permission to sell in case of delayed return, or adopt any lawful way possible:
فإن طلب الغاصب من القاضي الأمر بالنفقۃ أو البیع لایجیبہ لأنہ مضمون علیہ ولکن إن خاف القاضي علی العبد الضیاع باعہ القاضي لا الغاصب وأمسک القاضي ثمنہ لمالکہ، کذا في الدر المختار 5:376
