We use Paylease with Rent Manager, but only the Cash Pay part. You will need to think about your tenant base and what would work, not work. Since 80% of our residents pay by MO, we decided Cash Pay was best.
Yes, people will pay the $4 for the convenience of paying at a Walmart when they are shopping and get the assurance it is being deposited directly into their account with us - no chance of MO getting lost, stolen, etc. The $4 cost is not much as there are some places that only have a $500 MO limit. Many of our residents given us 2 MOs to cover their mostly rents which ends up costing them $5-7 total.
PS: one odd fact with threw us off. Our mostly Hispanic park has very low Cashpay adoption while our mostly caucasian park has over 50% adoption. I am theorizing he hispanics are very weary of trying new things they are unfamiliar with.
