There are many reasons for someone to need a temporary place to stay, but most traditional rentals require long leases. Having access to a rental that offers temporary stays is ideal for people who are moving to a new area, staying somewhere temporarily for a work assignment, etc. Rather than committing to renting a place for much longer than you need it, you can stay somewhere temporarily and move out when you're ready without penalty.
Here are some of the benefits of temporary housing rentals:
It can be very hard to find an apartment rental with flexible lease terms, even though there are many situations that make them necessary. Your landlord usually wants you to stay as long as possible, so they have a guaranteed paycheck coming in each month. Temporary housing rentals are specifically made for people that don't want to sign a long-term lease and you can rent one with lease terms that are based on your needs.
Many people who need to rent a temporary housing unit need to get in there as soon as possible. You could be going through a divorce, your home could have been destroyed in a fire, etc. If you need a temporary housing rental, you can usually get into one within a day or two, which is much faster than standard apartments.
One of the best things about temporary housing rentals is you can usually find furnished ones. Since you only plan on staying there temporarily, it might not make sense to move in all your belongings, only to have to move everything out again in a short time. Some people don't even have furniture to use anyway, so having access to a furnished temporary housing unit is their only choice.
Cheaper than a Hotel
In many cases, when someone doesn't want to stay somewhere long-term, they'll choose to stay in a hotel room. The problem with staying longer than a few nights in a hotel is the price adds up very quickly. If you stayed in a temporary housing rental instead, you'd save a lot of money.
More Space than a Hotel
Another benefit temporary housing rentals have over hotels is the size of the units. Hotel rooms are usually pretty small and it's hard to feel at home staying in one. Temporary housing rentals are around the same size as regular apartments, so you'll have more living space and it will feel more like home while you're there.
