We are considering a couple of approaches:1) Buy a 2- 4 unit and occupy one unit.    

Do these laws only apply to owner occupied pre-foreclosures, or would they also apply to NON owner occupied preforeclosure SFH, Multifamily, commercial, mixed use, vacant land, etc? 

I'm obviously not going to rent the owner occupied unit out, but do I physically have to be there or does it have to be somewhat furnished?

Assuming you occupy one of the units, the costs associated with your unit are not expensed or depreciated at all…they simply raise your cost basis for gain calculations when you sell. 

Usually if you owner occupy you have more leniency than if you’re solely an investor.

@Drew Sygit maybe you misread or I didn’t properly explained.. surely I know Section 8 bares no responsibility while the tenant is gone, I was stating while she was still occupying the home, Section 8 cut off payments.Update: It was a mess but ultimately she was removed within the last month.

@Jeffrey AllenMy answer is it depends on if the note is owner occupied residential, commercial, and the number of notes you own.After experiencing lousy service from a couple of servicers, we decided to service our notes ourselves.

Thank You,Most GSE OO / primary loans have you stipulate you will occupy for 1 year as your primary unless you sell. 

They are occupied with paying tenants and I've owned them for almost 3 years.
