Cost of repair materials lower.Then there are disadvantages: possibly lower quality tenants, lower quality homes.I'm about to take the plunge into renting them.

My first thought would be that whatever area near Turner that would suggest positive cash flow would be a low quality area/property and much riskier, potentially negating the cash flow.

We never buy a property unless it has sufficient positive cash-flow to meet our CoC criteria (opportunity cost + 3-5% min depending on the quality of the cash-flow).Coming from an experience where mortgage amortizations are <=25 years (residential) and no more than 30 on commercial and terms are typically 3-5 years {5-years being the most common} and no longer than 10yrs {which you would be foolish to take given the rate premium}, cash-flow is something you actively manage over the life of your holding.  

For an issue like indoor air quality, though, tenants could make the same claim and send their landlords down a similar rabbit hole.

I would certainly talk to a GOOD mortgage broker and see exactly what he needs to do to get him into a quality loan product sooner rather than later.there might be a few key steps he can take to speed up the process.

If anyone in Dallas, Texas is looking for a top quality and really honest repairman, PM me and I will get you his contact info.

We offer high-quality properties and are extremely responsive to all requests.

Buy a quality duplex that has curb appeal so you don't have to deal with the turnover issues.

I like Holly Spring because it is less pricey than Cary and Apex while the tenant quality is good.

IMO, paper returns will not be as good in better areas, but you typically get better appreciation, higher quality tenants, less turnover, less hassle.
