G'Day Alejandro,As a few have already mentioned, take a peak at Toledo also.In my opinion lower potential for long term appreciation but solid/"boring" cashflow.I prefer my portfolio to be "boring" but cashflowing lolLow entry points (Sub $100,000), high rents (Above the 1% rule).Blue collar working class decent folks that will stay and pay.Depending on the area but no derelict homes, yards well kept, cars with wheels and all tenants are employed.Plus, all are sophisticated enough to pay rent online so property management doesn't have to collect rents with bullet proof vests and shot guns lolI'm bias toward Toledo but it's worth considering.Wishing you much success
