> if person A and person B both pay on time and don’t trash the place then they are quite fungible.
Based on those two sole criteria, no, they aren't. Person A might call weekly about trivial matters that they should be taking care of themselves (lightbulb burned out, oven needs cleaning, refrigerator water filter needs replacement, etc.), while person B just takes care of things and doesn't bother the landlord.
Yeah but you can’t eat your cake and have it too. Part of renting is responding to complaints. If you don’t want to do that then you shouldn’t be renting.
I had a landlord ask me “you’re not going to call me for basic things right?”. I’m paying you money, I’ll call you whenever I want. Didn’t rent from him. You can tell me do it yourself but why would I put money into someone else’s property?
