best rent collection/management software for 1-5 units

[Tyler Neison]

What is the best software service out there that is under $20 a month to use for the tenant to pay rent and submit any maintenance issues? The only one I've heard of so far is RentRedi. I only have 1 sfh property right now that I would use this on but plan to get into some commercial/industrial properties in the future and would like to use the same service...

Thanks

RentRedi is not the best. Their payment processor is terrible and tenants will complain monthly about "error codes on payments" 

Also they never get my notifications about updates at the property.
