Feel free to touch base with Ian or myself and happy to assist some of your clients in finding investment properties.

If someone decides to live there, that is their choice.

I rent out the downstairs 3br 1ba unit and currently live in the upstairs 1br 1ba apartment.

I bought it for 600k in 2002, and lived in it as my primary residence.

We want to buy a multi family of 2-3 units and house hack by living in one and renting out the other one or two units. 

@Basit SiddiqiI have a CPA and have used one from 2019 forward because I work overseas as a civilian defense contractor, so I need the assistance of a CPA to handle the FEIE as well as the K-1.

Does anyone have additional information on buying from auction sites and/or living in the Broward/Palm Beach counties and willing to mentor a newer investor on the process?

There is a guy already that removes trash and moves coins around from machines etc, but the seller lives locally when it comes to taking the cash to the bank for deposits. 

The implication from your question screams that you absolutely need assistance and insight from an experienced, knowledgeable REAL ESTATE attorney to help you understand the risks and protections available to you in the type of transaction you describe.

They require the person assuming the loan to live there.
