I am a property manager and I can not think of anything I can not already do in GHL for property management. Sites, Forms. Calendars, Communication with email or text, tracking move in / out dates with tasks and daily workflow. Using DocuSign or DotLoop I can integrate all documents that need signature. Using upload I can store all documents on a tenant record. What I have found useful is to modify the contact type field to hold the values that make sense like "Tenant, Vendor, Realtor, etc.." Be sure to keep the Lead value as it is the default. I also added custom filed Lead Type that holds the same value as Contact Type because in some workflow situations Contact Type is not available but a custom field is. Ads flow to a funnel, prospective tenant fills out an application (form) and pays fee with credit card, Previews inventory, requests a showing, fills out a contract to lease that is followed up when accepted by landlord with a lease. Makes escrow deposit, schedules move in walk through and sings on phone the property condition sheet that is used at move out to determine any charges against the deposit. Payments, 5 day notices, evictions, all already able to be done in GHL
