Hello, been a couple days with no responses so I'll bite.
Since you are FIRE, then this should really be more about what you want to do as long as it doesn't come at a financial detriment. FIRE should mean the freedom to do the things you want to do. Seems like you want to sell it so I think you already have your answer especially since you think you'll make money on it. Are you relying on it for cash flow? If so, then that changes things.
To do an actual calculation, I think we'll need some more info, here are some questions which could help?
-What is your annual total rent that you generate?
-What is the total square footage?
-You mentioned multiple rooms, how many total units are there?
-What is your loan payment?
-Any other expenses not listed below?
Last, how did you meeting go with the renter?
