Properties are visibly kept up but no real maintenance is done. Have put in maintenance requests multiple times and am told "Sorry it's on back order" or some other excuse. Excuses frequently changed. Complained to corporate they were friendly but redirected me back to the local office which was then offended I complained to corporate because they wouldn't correct issues. Now maintenance enters the property regularly without notice (have dogs). Today they entered for a service complaint that neither I nor my girlfriend filed. Don't rent from Nolan it's a slum lord company.
