@Darrell Overly  there are certainly enough mobile homes in the area around phoenix (East Mesa/Apache juction) but your issue may be the age of the homes and any limitations the park has on renting.   

Start with a contractor that has a lot of 5 star reviews.You can join some facebook groups and network with investors in your area.

In my area (DFW), we're seeing that smaller, one-story office is doing well. 

Paid a top local esigner to come have a look and all she did was insult our cute little place that was doing just fine.....But I think where a designer could add value is by suggesting unique areas, like game rooms, coffee bars, outdoor BBQ/play areas, and stuff like that. 

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.

Go to BUILD YOUR TEAM at the top of the screen and look for local investors or meetups in your area.

Both properties are in A areas with great tenants. 

question depends entirely on the area you are investing in.

I think this discussion becomes a lot more nuanced on single family homes because they typically are situationlly turned into rentals like yours in nicer areas.

(this has happened to me before here in Florida) Once you get more info from the agents you can hone in on which area you need to focus on.
