.- I live in Raleigh, 10-50 unit complexes will be hard to come by unless you're okay paying a premium.

Over the past decade I have invested as an LP in about 50 apartment complexes. 

Does the condo complex have rent to own percentage restrictions (they all do, you want to know what percentage is allowed and what percentage it is at now)?

One complex I own in replaces up to the studs.

These systems are becoming more sophisticated and (my favorite) capable, leading to improved user experiences and potentially freeing up human employees to handle more complex tasks and interactions.

They are 100% correct.The downside sometimes to forums is people have a superman complex and get the impression real estate is easy as they think everyone is doing it and just jump in without the knowledge or expertise.

Here’s MY general feeling; if a MHP isn’t TOH, or I can’t easily switch from POH to TOH, then I might as well purchase an apartment complex and have less problems.

It just adds complexities and costs without any benefits. 

From my research, I'm seeing $100-$150/sqft depending on complexity and material.

A good friend of mine, managed a similar transaction last year: he merged several single-family homes around Florida and exchanged them for a mid-size apartment complex in Chicago.
