- you should remove tenant’s name from comms here as you are potentially breaching privacy, data protection etc
-people can stop responding to whatsapp messages for all sorts of reasons (illness, phone died etc). It’s only been 4 days
-you are a LL not a social worker tho your concern for tenant is commendable
-unless you have a reason to be concerned for tenant safety, I would suggest leaving well alone. If you do have reason for concern you need to document it and it’s then an emergency situation
-try calling. And then contact via other means (can you ask a family member/emergency contact to check tenant ok? ) Non response to some whatsapp does not justify going round.
-unless the furniture was agreed in the tenancy agreement and optional, and you have agreement in writing it is likely to be illegal under Tenancy Fees Act - think possibly it either has to be part of higher rent for a furnished property or it’s not allowed but get legal advice rather than relying on fora like this
Guidance here on what is allowed Tenant Fees Act 2019: guidance - GOV.UK
Also this prev thread Furniture rental agreement - one off cost
-if you don’t get any response after a couple of weeks ask your legal advice or LA or landlord association for advice on next steps. If non payment is the issue rather than safety it’s like any other arrears - document and try to establish contact via other means (phone email letter etc). Constant whatsapp messages could be harassment tho so be careful
-you could reasonably schedule an inspection visit to check how tenant settling in etc (needs at least 24h notice) and unless tenant refuses because it’s an unreasonable time you can visit, as per Shelter advice to tenants. Then speak face to face and take a note of the conversation and send after for the record. But I wouldn’t do it straight away or just because of non payment for the furniture
-doubt non comm after 4 days would be a breach of tenancy terms but check your tenancy agreement. May be a clause about telling you promptly about issues needing repairs but unlikely anything says they have to respond to whatsapp messages about non payment within 4 days
Good luck
