Granted section 8 does have more red tape.

I suggest you get with the SA Housing Authority, it's one of the best in the country (next to ours, hehe), ask them what areas are in demand, not what area to "red line".I love the area, not real familiar overall, it's a big city, but I might suggest you look around FT.

I recently got multiple red tags on a property for unpermitted work that was completed by previous ownership. 

I believe they have streamlined FHA 203K loans when the rehab is less than $35K which has less red tape associated with it.

All of them have red arrows with prices coming down, I think one out of 3 pages of listings is pending.  

It's always a bit of a red flag to me when there's no mention of the people behind the company on the website.If you're looking to invest in Detroit I'm happy to help.

That's a giant red flag for that grocer potentially declining to renew their lease, vegan gluten free customers don't want to walk through a cloud of cigarette smoke to get to their ethically sourced non-GMO organic avocado, and obviously the "no smoking within 50 feet" sign is going to be ignored by the customers of that neighboring business, who are all a bunch of smokers.

There is a lot of red tape involved with NACA.

The involvement of onsite management, often seen as a potential red flag, can lead to the property failing crucial qualification tests.

So, if you buy a house for 50k and turn around and want to borrow 100k the next day that is a red flag.
