I own rental in Temecula and it was somehow difficult experience to find quality tenants there.
I know one guy who owns 7 homes in Temecula and he went through 2 evictions over last 2 years. One eviction was particularly tough and cost him $20K in lost rent, legal fee and clean-up cost to the property. A few months ago he had another tenant could perform 2 months into lease term and he felt fortunate that the tenant agreed to leave by themselves when they couldn’t pay rent. This owner is a professional real estate developer/investor. He also has a realtor to list and screen tenants.
In Temecula my definition of good quality tenants:
>700 credit score and >$80K annual income.
In San Diego the definition is > 700 credit score and > $100K in annual income or even higher depending on the rental neighborhood. Generally the tenant pool can easily satisfy the requirement in San Diego.
