This influx of workers will naturally drive demand for housing, retail, and other services in the surrounding areas, especially in smaller towns and cities that haven't seen major growth in decades.

Yes, the bi-yearly nit picky inspections can drive me crazy, (torn screen , etc) but in the long run it’s worth it.

Detroit is appreciating rapidly, due to many factors, and it still cash flows or at least allows you to operate near break even.

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).

Last night, I heard an inspiring story about a mom who brought her young kids along for a 45-minute drive to tour an investment property.

. :)Anyway, I like your strategy of driving and looking for houses in need of repair and sending handwritten letters and contacting rentals for the reasons you gave.

You did not mention how far they are from you which is also a factor.

@David SamIt depends on a number of factors. 

Factor in accurate, but worst case scenario numbers.

Your NOI, revenue, location, risk for the business, assets (land and infrastructure mainly), equipment (yurts would be considered business equipment), and more all play a factor.
