. :-) I found the realtor from BiggerPockets, and he seems to have a solid reputation.

Many OOS investors set themselves up for failure because they don't invest the time to ACTUALLY understand:1) The Class of the NEIGHBORHOOD they are buying in - which is relative to the overall area.2) The Class of the PROPERTY they are buying - which is relative to the overall area.3) The Class of the TENANT POOL the Neighborhood & Property will attract - which is relative to the overall area.4) The Class of the CONTRACTORS that will work on their Property, given the Neighborhood location - which is relative to the overall area.5) The Class of the PROPERTY MANAGEMENT COMPANIES (PMC) that will manage their Property, given the Neighborhood location and the Tenants it will attract - which is relative to the overall area.6) That a Class X NEIGHBORHOOD will have mostly Class X PROPERTIES, which will only attract Class X TENANTS, CONTRACTORS AND PMCs and deliver Class X RESULTS.7) That OOS property Class rankings are often different than the Class ranking of the local market they live.Class A is relatively easy to manage, can even be DIY remote managed from another state.

I learned this by subbing to remediation companies.

@Manuel De La Cruz Are you using the C-Corp as your property management company, only, or did you also purchase or transfer the property into the C-Corp. 

Title companies and attorneys are very wary of powers of attorney, or even notarized statements.  

Insurance coverage is another separate paragraph - typically the Lessee (laundry company) will spell out how much PL & PD insurance coverage if offered.

To answer your question, I would say you need +100 keys to achieve the economies of scale and feasibility to hire a property management company.  

Curious to see the positives/negatives of some of these other mentioned companies.

As a reminder, Madoff "had annual audits".Part of my DD, while I do ask if a company has audits and shares them with LPs, I also ask for FULL financials: Income Statement, Balance Sheet and Statement of Cash Flows for properties through partnership level items.
