What key aspect is NOT typically included in rental history investigations?

In rental history investigations, the focus is primarily on aspects that directly relate to a tenant's reliability and their past behaviors as a renter. Payment history is crucial as it indicates whether the tenant consistently paid their rent on time. Previous landlord references provide insight into how the tenant interacted with prior landlords and whether they adhered to lease terms. The duration of previous leases can show stability and responsibility in maintaining tenancy.

Personal character references, while potentially useful in some contexts, are not a standard component of rental history investigations. They tend to focus on subjective perceptions of an individual’s character rather than their direct rental behaviors or history. Thus, character references do not provide concrete information about a tenant's past renting experiences or reliability, making them less relevant for assessing a tenant’s suitability for a new rental arrangement.
