Essentially there is a property management company that finds investors to pay for the build of duplexes that are then sold for 30%-40% more than the cost to build.

Additionally, the management of a bigger property does not linearly grow -- what I mean is that a 12-unit building doesn't require four times the management of a 4-unit building. 

You could learn the necessary skills to furnish, market, & manage the other unit.

Even if you manage to be the first person in history to maintain the corporate veil of a tiny corporation.

Furnished and Managed What was the outcome?

Make money, save money, buy a house in a neighborhood they believed in, manage it well, and hold it forever.

If you have the time and experience, hiring your own subs (like plumbers, electricians, painters) can save you some money, but you'll need to manage the project yourself.

I have a team of professionals working alongside me including a real estate broker, contractor, project manager and hard money lender. 

These often generate higher income compared to long-term rentals, though they do come with increased management responsibilities.- Improve Property Management Efficiency: Since you handle management yourself, consider investing in property management software or hiring a part-time assistant, even a VA.

So my equity loan should be easily manageable.
