Real estate is so complex at times and people get lost instead of applying common sense to work through problems or issues, or just the everyday managing of your investment(s).

It has been a LONG time since I dealt with large apt complexes.

There is a lot of turnover in the management business and I would suggest visiting all the large apartment complexes in your area to apply for a job.

I my self had some pretty rough goes with it in Detroit I walked away from 2 homes that I let go to tax's and lost right at 100k... its a rough rough town and really not sure if its fixable or many of the low life inhabitants are fixable.. there was a pretty compelling pod cast about the whoa's of Detroit a few weeks back.. obviously there are good ares of the city but the bad one's boy are they bad.yes i believe i heard about that in the podcasts, an apartment manager was shot and killed in a complex about a mile away from where most of our units are located. we always take a non aggressive approach to dealing with people  i believe thats why we are still in business today. detroit since i can remember has always been a high risk high reward location. im sorry to hear of your 100k investment being lost, weve had to let go of a few houses in the area as well. homes we buy in Detroit pay monthly 5-7% of purchase price.

There are some complexes in the area that target students but students are generally unhappy with their experiences there, so there is certainly an opportunity/market.

The structure gets much more complex in a commercial transaction.When was the leases originated ??

The good news is I'm getting very close to closing my first multifamily property but the bad news is I woke up this morning thinking about my inexperience regarding the differences between leasing a SFH versus inheriting existing tenants currently in the complex.

Some apartment complexes have a staged unit that they show.

It's about what you can invest in that meets your goals without adversely affecting your quality of life to an extreme degree.I have a friend who owns 3 different complexes of hundreds of units.
