Most homelessness is also temporary, with around the same range of 80% moving on within a year.
That being the case, the value-added of free housing appears marginal compared to the cost. It would best target those who are a) chronically homeless, but b) neither addicted or mentally unfit to be employed, which sounds like a vanishingly small demographic. Mind you I take "effective" and desired outcome here to mean that they won't continue to roam out in the streets, either to be close to dealers or from being mentally unwell.
