If I told someone "yes, I will rent my house to you" via email, but nothing has been signed, am I legally stuck with that person as a tenant? Or can I rent out to someone else? Getting conflicting answers.

Hi guys, new to renting out my property. I have 3 candidates.

Candidate A was the first person to ask about renting. Wants the whole place (2 bed/2ba) at a discount from Jan-May 2026. I wasn't getting a lot of bites at the time, so I said "yes, I can rent to you for x amount for 5 months." Figured something is better than nothing.

Candidate B and C both reached out shortly after and said they need a place ASAP because they are starting their first year of medical school next week. Full rent for a year.

Sent them all applications, candidates B & C completed everything right away and passed background/credit check. It's been 3 days and candidate A has not completed anything.

I would really like to move forward and send lease agreements to B & C and let A know that the house is no longer available. But since I previously did say "yes", could there be any legal repercussions for changing my mind? Help!
