But there are plenty of rental markets where you can be forced to rent without seeing that exact unit first. Common in big complexes, where you might get shown a "similar unit" or in markets where rental vacancy is so low that if you don't apply & sign within hours, you aren't getting that apartment because there's 20+ potential tenants for every rare vacancy. The current renal home I live in I rented without seeing it in person first because it was the only vacancy at the time, and in that market you must be first to sign the lease or you lose.
