Apparently a few years ago Provence did a condo conversion and kicked out all the tenants.
This is my best recommendation at the edge of Foothill Ranch. It is very quiet along Paloma at the end of Portola. Some units have a fantastic view of the Irvine flatland. The 3 BRs is a fairly good bargain.

On the downhill side of Portola there are 3 private home communities. They are starter homes but over the last 2 decades owners moved up to a larger homes but kept them as rental investments. The smallest is called Vineyard. There are 14 townhome and flat attached units around a motorcourt.
The next one up is Brittany 5 detached homes around each motorcourt. It has fantastic view but avoid the units next to the toll road. These are single family homes and rent should be very reasonable since the owners bought them for $140k back then and don't need to meet rental parity.
The larger private rental detached home is KB's California Coventry at the corner of Alton and Portola. It is across the street from In and Out. There you will find a single family detached home rental with a driveway. Again these were once starter homes where owners likely decided to hold on to them as Irvine fringes are excellent rental market.
Good Luck with your search.
