NWR- How long to wait to hear back on a rental application?

We've been discussing moving for awhile. We've looked at several different places and finally found a place we love. We would be renting a townhome and moving out of our small apartment. The townhome isn't available until Mid-June because the current tenants are in the middle of closing on a new home. The landlord will also will be putting in some new updates to the place. We put in our application last night. How long does it typically take for a rental application to be processed by a private landlord? We have both only lived in big apartment complexes with different managers and we've gotten notice in about 24 hours if we were approved or not. The landlord said his process is just calling and verifying rental history, employment, and checking for a criminal record. I know no one has called to verify my work yet since I answer the phones. Patience is not my strong suit lol
