Shell condominiums with no interior finishing are being sold (and flipped I suppose) for almost a million dollars.

That plus the low growth rate in household income and the bad schools. 

Just off the top of my head, things I would consider to be relevant in assessing the "health" of a community are demographics like the average age of people living there, percentage of the population who are home owners (as opposed to renters), average household income, recent economic growth of the region, the kind of jobs coming in to the region. 

My goals are to build a second income for my family that will replace the lack of a dual income in my household. 

As condominium associations struggle with financial burdens and defaults increase, the lifestyle and environment they were built for facing increased strains.

If the wife is not on title, not on the loan, and not living in the same household as the husband, she is irrelevant to the bank, as far as income. 

We will say 736$ Total renting and household cost to you then is -400$ Now if you live in one side, Making big assumptions here total income:1000$ total rent but you apply the 50% rule to the total possible income2000 possible income *50% -1000(your side) - mortgage 654$Total renting and household cost to you then is -654$I am not saying to go one way or the other!

We always prefer if it's 4-6x+ higher, and also prefer dual income households for that reason, although it always boils down to best candidates.    

So, about me: grew up in an immigrant household, first generation American, lived in Chicago my entire life.

The per capita income is ~24k and median household income is ~50k.
