Morally speaking I don't think it matters in and of itself. There's a power imbalance that needs to be critically engaged with so it doesn't become a problem, and there's a small to medium influence on your material interests that may color your perspective on things if you aren't ideologically disciplined.

Treating people well and being nice and trying not to exploit people is basic, individual morality, trying to be good.

Leftism however is about trying to understand and change society. It isn't about lifestylism or poverty or personal purity.

Categorically speaking I wouldn't consider you a landlord. Your material interests likely don't align with the landlord class, assuming you still have to sell your labor to survive. Of course you (or others in your material position) might adopt an aspirational consciousness that aligns with landlord ideology-- I've even seen that from people with no private property whatsoever, nothing at all with which to rentseek. Temporarily embarrassed millionaire types.
