While Milwaukee does not score a number one place in different rankings, it scores pretty good and in combination with other favorable factors, like lifestyle, cost of living, education, schools, employment etc..I am curious, what was the zoning code change in 2010.

Not a favorable direction in Texas. 

I own a duplex right outside of city limits - LOVE the Brickwall Tavern in town - if you've never been, do yourself a favor...First, let me share my "demands" that have served me well through about 3 years of renting my duplex right there in Burlington:Applicant must have current photo identification and a valid social security number.Applicant's monthly household income must exceed three times the rent.

Sell it and invest in a more favorable market.

So long as the Mortgages get paid, it's usually not an issue.Going forward, I have scheduled salary increases that will shift my DTI significantly into my favor. 

Of course if I can’t find favorable terms then I’ll basically do what you’re saying, but it’s my backup plan

Even if you were in a market for favorable for investing (cash flow investing at least), house-hacking doesn't always pan out to be what people assume it is.

S Corps are no longer a "no brainer" and it's better to make an S election a year or two into the business than set yourself up from the start in an S Corp that is actually not favorable to you in this professional's opinion. 

I deal with contracts - non RE - frequently, and they always favor the person who writes them. 

I used to beg for turntimes of under a week, calling in favors and stuff like that.
