All you would need to do is talk to a loan officer and take a look at some. If there are already renters in the units, you may be able to count the rent as income since there are rental histories and leases.
This is an example of one available: http://www.trulia.com/property/3044390869-63-N-Prospect-Ave-â€¦
Just move into the bottom unit and change it to your taste as you live there. Getting a deal like that would be a great way to start your investment portfolio. Nice to start with a home that has an instant $900 in rent and has been reduced over $50,000.
