if the attic gets hot you do not want to store beans up there.
if you keep the beans dry and out of direct sun and stored in moderate temperatures they will last longer.
i don't have freezer space either, i try to renew my beans every three to five years. most seem ok with that. i do notice that some varieties do not store as well as others so they will self-select themselves out as some beans i can't regrow that often.
if you keep organised and can store samples in smaller containers or those plastic envelopes i think you can keep those pretty long times and if you don't open them they may store longer, but i really am not sure as i've only kept most of my samples in small 2oz plastic sample cups and those probably leak a bit of air. i also sometimes do open them up again to get samples out or for planting.
what really helps is making sure to write the date the seeds were grown. i write the date on a bit of paper and put it right in the container since i don't like writing on the containers. i also write down the name since some of the beans i have may look like other varieties.
