@Timothy Ray Lots of great advice here. As a property manager myself, I’d add just a couple things that I haven’t seen anyone else mention:
1) Ask if they can take rent payments by automatic bank draft or credit cards. And if they pay you your profits electronically as well. Obviously better companies are better set up with technology.
2) Ask if they screen applicants by pulling and reviewing their actual credit reports. There are some PMs that just use a service to get a credit “score” report and that’s all they use. Better PMs are set up to review the actual credit report.
Finally, whoever you choose for a PM, I recommend also letting them find your tenant. Sometimes realtors will help an investor buy a property and then lease it out too. Then the property is turned over to a PM. More often than not, the tenant the realtor finds may have red flags that the PM would have seen but now it’s too late. Help yourself out by having the PM find the tenant. Best of luck!
