That really depends on what you wish to use LandlordStation for. If you are simply running a tenant screening on your applicant and handling the rest of your property management outside of LandlordStation, there's really no need. If you plan to take advantage of the tools LandlordStation has to offer, you may wish to make sure they've set up their Tenant Portal.
If you, as the landlord, have a Free Membership you have access to document sharing as well as the ability to accept work orders through the Tenant Portal.
If you have a Starter or higher membership level you will have access to Online Rent Payments, E-signatures, and a number of other tools at your disposal, many of which will require your tenant to have access to their Tenant Portal.
