It’s just not worth it in Detroit especially with the low price points. 

And like many other cities, vacancy rates are still low, lots of demand for housing of all types.  

That's a very low amount given it's a commercial property.

@Stephen FlemingFrom my experience working with over 400 investors, your strategy of leveraging a low mortgage rate, tapping into home equity, and diversifying with a short-term rental (STR) in Northern Michigan is well thought out.

However you should consider if your loan has a Pre Payment Penalty.

By targeting better locations, leveraging Section 8 for consistent cash flow, and balancing low acquisition costs with high guaranteed rents, you've achieved impressive results like $1,100 in net cash flow on a single property.

Look for a location with low crime, then look for the neighborhoods with the best schools.

So making it my primary is a low bar.   

@Cory Prior There are ways of doing low-money down strategies.  

You’ve developed a moderately fast wealth accumulation strategy that’s relatively low risk, enabling you to ride out down cycles, negative cash flows, unexpected necessary expenditures, etc.
