I believe on the Meet up app theres a group of Realestate for El Paso.

Most tenants do not have an issue supplying them.If you are developing a tenant screening app you would need to remember who your customer is, the landlord, not the tenant.

Does the app allow you to view webinars?

Adams county site gives a fair amount of information, do you have access to myfirstam app?

Could it be because I'm using the app and not on a desktop?

I just use an app called Magic Plan.
