Later if you plan to scale your portfolio you may decide you want PM services.  

When things scale systems become required to effectively manage property, and if it's not a focus of the company the investor will eventually be the one hurt in the process.Obviously I have no clue who you used to purchase the home and/or manage the property... just my 2 cents on the topic.   

I look at my monthly statements from my property manager and realize how truly little they make per month off an individual property I wouldn't even drive by for that amount hence the scale needed.

Background: 5) a large vacancy (reportedly 2200 sq ft.) last year, (which is now filled) prompted seller to list property for sale but with no takers. 6) since then seller has filled the space. 7) seller has owned it for 10 yrs possibly buying at the height of the market. 8) seller has made some exterior cosmetic and mechanical improvements in that time. 

My renters work short term jobs on large metal erections at a petrochemical refinery and nitrogen fertilizer plant.

@Samantha Alexander I've been on Zillow, Realtor.com, Homes.com, etc and paid a large amount of money per month on leads.

If a tenant's belongings are damaged because of a large leak in the roof top AC unit which is obviously the landlord's responsibility...

If the latter is the answer then that is your number one hold back for scaling.

We will continue to scale up into larger commercial opportunities.
