I can envision that the numbers on these luxury homes would lead to to a long lag time...but hopefully I'm wrong.

We don’t know any PMCs to recommend in the area mentioned, but since selecting the wrong PMC is usually more harmful than selecting a bad tenant, you might want to read our series about “How to Screen a PMC Better than a Tenant”:https://www.biggerpockets.com/member-blogs/3094/91877-how-to-screen-a-pmc-better-than-a-tenant-part-1-services-and-processesWe recommend you get management contracts from several PMCs and compare the services they cover and, more importantly, what they each DO NOT cover.

@Kyle Cross, correct me if I'm wrong, but I think maybe what you're getting at is potentially pitching to your parents that you would like to take a shot at personally managing the units to gain experience and some form of compensation.

Take all your analysis that you did for the deal to court so you can explain why they got the value wrong. 

I've seen banks be very competitive with blanket loans that cover multiple properties and/or multi-family properties, e.g. 5+ units.Mortgage Brokers (obviously I'm biased) - Brokers have the ability to work with all of the above and can get you to the best lender for your scenario right away instead of having you waste your time with the wrong type of lender.

Wrong!
