I've always found inventory rates (and how they've moved over time ie previous 1-2 years) to be the starting point for where a market's health is at.

You can get solid cash-flowing single families in the 90-120k price range and duplexes in the 130-180k price range.

Here's the latest market report (based on single family homes):🏡 Mortgage Rates:30-year conventional rate today is 6.72%30-year VA rate today is 6.15%——————————————————————————————————💰 Median Sales Price:Sept: $490,000Oct: $485,000Nov: $484,995——————————————————————————————————📈 New Listings:Sept: 1,910Oct: 1,959Nov: 1,481——————————————————————————————————📅 Median Days on Market Until Sale:Sept: 20Oct: 22Nov: 24——————————————————————————————————📦 Months Supply of Inventory:Sept: 3.3Oct: 3.3Nov: 3.0🤔 What does "Months Supply of Inventory" mean?

Do you want a company that will keep the long-range investment objectives in mind or one that focuses on today and today's profit alone?     

There are approximately 28 Multi-family duplexes active on the MLS ranging in prices as low as $50,000-$219,000 with a median rent of about $929.

However, you will get a range of perspectives because several here don't mind and even brag about losing monthly.

I am hoping to view all cases among ranges of dates (i.e 2 week increments). 

You typically need to be in the $400-450k range to see those rents.

Typically this takes 6–9 months, including 2–3 months for permitting and 4–6 months for construction.You can browse their current plans online, with design costs ranging from a few hundred to close to $2,000: ADU Fast Track Plans2.

With interest rates on your current properties in the range a stock market portfolio might return paying off the mortgages could be a good option so you maximize cash flow.
