Make sure there is enough space for all your belongings in the warehouse you will rent, since there are several options in the market that sell measures and cost per square meter, but they never make sure that there is enough room in a single warehouse, thus making you rent an additional one. Make sure this does not make you have a hard time.
Pack everything safely, since the storage is usually for a long period of time.
Simply code all the packed boxes alphanumerically, making inventory tasks easier.
You should always know the working hours of the warehouse.
See if the warehouse administration provides packing supplies.
Ask about the shortest time that you can rent the warehouse for.
See if there is a human team, as well as carrying tools.
Ask if they offer transportation service.
