What's the biggest challenge you're facing?

[Account Closed]

I want to find out the biggest problems property owners, agents, managers, companies or others in the industry face and provide a solution using web/software or technology. 

Would love to hear about some day to day challenges you all face that you haven't found a solution for. Is it marketing your properties? Finding leads? Managing tenants/rent? Managing operations? Something else?

Thanks for the insight!
