A few observations.

I'm not saying it's a bad move, and this was just my single observation.

(How creative, LOL...ask me how the city of NOVI was got their name).Now, if you looked at this info above, most outside observers could come to a rational conclusion about property values, areas to buy for rentals,...flip, and so on...and, most would be wrong. 

I just want to observe and get experience on the process.

It is my opinion and observation that is the probable reason for this lack of closed volume, as, our months supply is actually not up much at all. 

This will allow you first hand experience observing what other investors are doing that is successful, give you great local market experience, but best yet, give you industry experience, learning laws, codes, leases, tenant relations etc..

Whereas a rental property that is not owner occupied would require a 20% or 25% down payment.Your observation, "-Lower payment means less money locked up in the mortgage, which can in turn can be used for other things (like more investments or renovations)" is correct and is one reason for keeping the down payment as low as possible.

I re-did the numbers considering observations made from various posters above. 

After a decade of keen observation in the real estate market, I've made the strategic decision to transition into the role of an investor-focused real estate agent.Rooted in a background encompassing both business and real estate, I assure clients of a smooth and efficient transactional process.

I'd say you are in a unique spot right now getting to observe a market with outsized demand for spots and higher earning inhabitants than usual.
