More Storage = Lower Turnover?

[John G.]

My business partner has a hypothesis that spending extra money to build an abundance of storage space into a rental unit will keep tenants "sticky". The idea is tenants will get more stuff and the stress/expense of moving will make them less likely to leave resulting in lower turnover and higher occupancy rates.

However I have seen many investors appearing to spend minimally on storage space and cabinetry to save money.

Opinions?
