I define a good tenant as someone who:Has stable employment in a market segment that is very likely to be stable or improve over time.Pays all the rent on scheduleTakes care of the propertyDoes not cause problems with neighborsDoes not engage in illegal activities while on the propertyStays for many yearsI next determined the tenant pool with the highest concentration of good tenants.

RE types are always concentrating on IRAs, but the retirement plan can be as simple as a self/private funded annuity from the LLC.

To increase your chances of always having a reliable tenant, purchase a property that attracts a tenant segment with a high concentration of reliable tenants.How do you find a tenant segment with a high concentration of reliable tenants?

It takes time and concentration.

Instead we concentrated on areas of max capital appreciation, but we never imagined prices would go exponential.Now we are seeing a lot of Canadians over here buying just for cash flow.Good luck...

Moving them out of the concentrated poverty and spreading them out does not decrease property values and helps, in the long run, alleviate poverty.

@Daniel Koren - for context I've been investing in Cleveland for the past 3.5 years out of state (concentrated on the west side).
