I think any business with strong customer lock-in, infrequent purchase decision, and an immutable monthly cost/revenue evolves into a business where the company tries to minimize support. Think of the level of support you get at a bank, cell phone company, etc. Awful. I'm not sure about the opportunity there. If you spent 2x on support costs, what would you get out of it? Tons of referrals when people are moving out? Probably not-- movers are busy and rarely have friends handy who are in that rare moment of hunting for an apt/condo. Now, SERVICES on the other hand... Certainly there's room for apartment buildings that have great gyms, social events, etc.
