I will "house hack" a duplex at my next assignment location. 

You can also use the search feature to locate ones advertised in the past to give you an idea of schedule.

Location is prime but it is overall a very industrial area and not a desirable one in terms of current housing.

@Michael Ablan Sounds like you may be buying in the "rust belt"  Is that where the properties are located? 

Also do you have any recommendations for locations to focus on or avoid? 

@Mark Christensen, Where is your 7-plex located?

Located in phoenix.Thank you in advance for some clarification,Michael Vallee

You have the right idea how far in michigan are you looking to invest(location wise)? 

im in a hot location that is pretty much zero vacancy. 

Or, you could just buy a SFR and live in it for a year, or however long and once you get new orders or whatever you can purchase a new one upon arriving at your new location, while keeping your old one so long as they don't exceed 450k.
