Pretty solid appreciation in that area with an average of 5-7% per year, and it's also close to a lot of industries like the Chrysler plant.

Any new commercial, industrial projects nearby? 

Looking at this mathematically, if you assume a 50% non-renewal rate (industry standard) and use the low end of the range of $5,000 per non-renewal, there is a loss of $50,000 per year on a 20 unit property.

While less than 10% of the mortgage industry offers 40-year mortgages, here's something to factor in: they often come in with a rate increase of 20-35 bps.Assume 35 bps.$300k mortgage at 7.25% (30-year): $2,046$300k mortgage at 7.6% (40-year): $1,996Technically, it lowers the monthly, but not by much once factoring in the rate adjustment.

We in private industry would expect heads to roll, massive layoffs and perhaps bankruptcy filings.  

For practitioners in the real estate industry, the biggest challenge is not just the difficult work, high risks, or immense pressure, but the necessity to learn to let go of complete control over outcomes.

@Julie Doke: Industry specific software speaks to you and you can easily relate it to your day to day process.

For example, I started investing in Buffalo (NY) a few years ago because I liked the stable population statistic along with the fact that a big chunk of the population is in the healthcare industry... along with major car manufacturers having plants or some sort of manufacturing factory there (Tesla, GM, etc.) 

There are Class A industrial projects underway and the development of a large retailer.

@Kyle Cross you claim to know a lot about the industry, but your questions are vague and so is the info you've provided.Not sure how managing 8 units doesn't, "require much management"?
