I'm new to real estate not sure what to do

[Brian Gallagher]

Bought my first rental (5plex) in June. Last week had a tenant (that came with the building) decided he wants to move to Florida with 7 months left in his lease. Asked if someone could take over his lease or be added and sent me a guys application. ( very bad app, just got evicted and left the past rental in bad shape) so I told him guy couldn't move in. Said if he wanted to leave I needed 1 full months rent and he would forfeit his security deposit also said if I was able to rent before the month ended I would return that part of the rent. ( he also owes me some $ for not switching his electric bill right away)

He freaked out and thinks that is very unfair he should loose his security deposit and is trying to find another person to take over his lease now. Not sure what to do.
