Subleasing involves renting part of or an entire space to another renter, but through the original renter.A sublet allows direct landlord communication with the subtenant, unlike a sublease, where the legal relationship is between the primary and subtenant. We talk about a sublease when the original tenant (sublessor) rents out all or some of the space to a third party (sublessee). Another thing to note is while subletting sooner will net you some emotional security, the later you sublet, the better deals you can get. This article covers the differences between subletting and subleasing, helping you understand the distinctions and make the right choice for your situation. Subleasing is when the person whose name is on the lease finds another person to pay the monthly rent. That person is the subtenant. It depends on how the lease is drafted, but generally the tenant can sublet the whole property if they obtain landlord consent first. Subleasing, or subletting, is when a tenant rents their unit to a new occupant.
