The process of buying

[toothiron]

My wife and I are trying to buy a place and have a question about the process. I am assuming we need to sub-let the apartment we are in when we find the place we want to buy otherwise we give up our security deposit by breaking the lease? IF we need to sub-let the apartment how do we go about doing that? I know a few people who would be whilling to sub-let the place then take over the lease when it runs out. The management company wouldn't even need to paint the place between tenants. In my mind it seems like a win win situation, but am unsure
Thanks for your time.
