First I assume when you say apartment you mean an attached single family home (i.e. condominium or townhome).

Condominium or condo is a form of tenure and other property, which indicated a piece of property (usually in apartment house) in an individual possession and use of and access to public facilities in the works, such as halls, heating systems, elevators, exterior areas is carried out in accordance with the rights associated with individual ownership and control of the owners association, which together constitute the ownership of the entire piece.

Any investor with one home has a major leg up on the average American household.

Two adults means more household income which I find is safer if one loses their job.

In my opinion, higher interest rates are suppressing housing prices, which are keeping demand on the sidelines, especially for the newest, largest generation who are now looking to form a household and move out of mom and dads (or their 8 dude group frat house, said my 26 year old self).

I agree with many of the other members of BP in this post, Detroit is not an easy market, still many pockets in the city, poverty zones, local Detroiters codes that must be attended, but at the end of the day is a powerful and big American city that is coming back (see GPD/Capita increase, unemployment rate decrease -still high for U.S. 9% in comparison with a national average of 3.9%-, an improvement in the family household income) that can make SOME investment thesis work properly. 

Her and her husband took some cash after consolidating households and bought an out of state property. 

If you can find an electrician, a plumber, an HVAC outfit, and a roofing crew that's willing to work with you in your target area, bless your luck and treat them like the vital business associates that they are.I would tell any head of household that's already making upwards of $100K a year to stay out of this niche.

So work on your household finance first.

With that kinda money you are near luxury living monthly out of pocket pmt.One more thing, even if roof is good (besides other necessary household utilities) 5k down pmt is a significant number for anyone ok living in 10k house neighborhoods.
