Hello @Brian Mathews
It depends on what you expect from a property manager. Before I continue, know that I am a Realtor in Las Vegas, and my business is almost exclusively with remote investors.
Most people think of property managers as someone who collects the rent after they buy a property. This is absolutely not the case. Property managers are a gold mine of information. Property managers know what rents and what doesn't because they deal with rental properties every day. If you talked to only one person about investment properties, talk to a good property manager.
Having owned over 20 properties and working almost full time with remote investors, one of the surest ways to fail is to manage the property yourself. I occasionally hear statements like, "I will manage the property myself to save the management fee." Don't do it, you will fail. For example, unless you have access to the right databases (you need several and they are not cheap) you can't even properly qualify a potential tenant (credit history is not the important factor). If the property manager does not save you far more than their fee, you are working with the wrong property manager.
When I first bought properties I managed them myself. I quickly learned some hard lessons:
* Tenants are extremely creative when it comes to why they are late this month with the rent. Also, you needed to be both firm and fair at the same time. Not a skill you learn in a few months.
* Cost management is critical if you want to maximize profitability. This includes preventive maintenance and remedial maintenance. Here again, tenants are very creative. One of my tenants called that there was a broken window at the property and wanted me to fix it. By this time I had enough experience to know what to do. I asked how the window was broken. He stated that there was a break-in. I expressed my sorry and asked about what items were taken. He stated that nothing was taken. I told him not to worry, that the window would be repaired as soon as I received the police report. A long silence followed my statement. I proceeded with, unless I have a police report, you have to pay for the broken window. But not to worry, I would call the police now and they would be out to make a report, gather finger prints and such. I explained that it was amazing what the police could do now. That even if the burglar scrubbed the window and all the broken pieces, it did not matter. The finger prints would still be there. About this time he decided to pay to have the window repaired.
* Evictions - No investor wants to believe that any tenant will even have to be evicted. Believe me, they do. I ended up having to take time from work to go to court on two evictions. I lost an entire day waiting for my case to be called.
There are several more reasons I could list but I believe that hiring a (good) property manager is the best way to save time, money, and effort. You can not afford to manage your own properties.
I hope this helps.
