I am a real estate "Novice" by all definitions of the term. My wife and I's families are pooling monies to get investment properties in Metro Detroit. We have secured 2 in the City of Detroit. Both have been cash cows. I knew the area REALLY well, as in I walked home through the area from college/work everyday for 3-4 years at 12AM-4AM. I still wasn't sure.
I am NOT a Realtor. I still was on the fence about the purchase because you hear so many horror stories about what happens to properties in the city. So my formula to buy or not? I sat in my car for 8 hours and watched who was walking up and down the street. I parked at about 6PM and stayed until 2AM and watched. What sold me? I saw 7-8 people walking their dogs between 8PM-midnight, by themselves. It told me it was worth a shot. My Wife and I live in the property so that secures it. The other unit is a 4 unit Mulit-family. We have a down-on-his-luck member of our church staying in one unit he pays a couple hundred dollars, but we rent out the other 3 at market rate successfully with no issues.
Most everyone on my street has a rental or two in their home they live in, or nearby. By all reports everyone is doing well...If you are buying in Detroit its zip codes 48201, 48226, 48202, 48208(careful), 48207(careful), 48214( REALLY careful). Here is a recent graph by the the local newspaper. Basically you have a street called Woodward(main street going through Detroit divides east and west). Anything in either directions 1/2 miles east or west from the (south)Detroit River to where Highland Park(north) on Woodward is a Gold Mine. We bought a house for $130K in July 2013, we have put $30K into the home, we live in two floors, and rent out a basement unit for $1000/month and the 3rd floor unit for $1300/month. Every home on our street has "Maid's quarters, Mother-in-Law Suite, etc that is generating the homeowner some nice monthly cash. The key is to be as close to Woodward as possible. I suggest no more than Five Blocks, off Woodward, or call the Wayne State Police ask them do they cover your address. My wife put the phone down to go outside to grab something and was gone for 20 minutes. I called Wayne State Police non-emergency line, and they had a car there in less than 10 Minutes to discover she was outside talking to our neighbor. Also, if you score a property near the Medical Center their Police Force or the VA Police(Veteran's Hospital) will patrol your neighborhood.
The Four Unit home was a little bit more risky but it cost only $60K. So we get $650 a piece for 3 units, and $275 from our guy from church. But we are banking on a major transportation project breaking ground within a year, and that $650/month will jump to $850.

The Model I see everyone doing is take a larger home cut it 2-4 different ways and rent it out. Live in one unit yourself, or have someone you know or trust stay in one of the units for a reduced amount.
