Krystyna, the couple suggestions that I have are:
1. Do you know any commercial brokers? If so, lean on them to find you a few investors that may be willing to do an off-market deal. If you do not have a commercial broker contact, interview a few.
2. For the 1-4 units you may be able to get different information on MLS reports than a 5+, but look for owners that have owned for 10-15 years with high equity and send them a note or give them a call. Tell them you are looking to buy.
Most importantly, your feet have to hit the street. I have not found that many deals will come find me unless I do something to get my phone to ring or build/foster a relationship with a banker, title company, commercial broker, REI meetups, lawyer, CPA, etc. All of these people talk with many more people than you could possibly talk with, you have to get them to think of you when someone says something about an investment property.
