@Michel P. Toledo is a good example of a city that you need to be careful. The population in 1970 was almost 400,000. Today it is about 275,000. The real estate has "surplus" housing as this population left.
And that surplus housing is reflected in the low pricing. The demand isn't strong.
Go to Zillow and type in houses in Toledo under 100K. And then under 50K. Lots of them. Try that in Phoenix, Nashville or other markets that population has grown recently. Places where people want to be. All houses are well over 100K in those markets.
Mr Ratiu's statistics are interesting, but the view on the ground is that the City is not growing. Recent populations statistics suggest this as well. Because the real estate is cheap, landlords can get some high cash flow returns, provided they can rent their units. Appreciation is another aspect for making money. Toledo's appreciation will be muted.
Again, Ohio focus in Columbus is a smarter bet.
