Hey everyone,I have a duplex in Killeen right now.

So I bought a duplex about a year ago using the VA home loan and doing the whole house hack thing and its going well.

I sold the first house I bought and moved to a duplex where I am currently living and I close on a 2bed 1bath house on Friday that I will rehab this month. this is the beginning of my Realestate journey and now I can honestly say that I am a Realestate investor!

I have a SFR that I want to convert to 3 or four rental units, I am confused by the IRC, definitions on duplex and townhomes, has anybody converted a big house into more than two units before, two stories, what is the big deal.mainly because of the commercial rezoning requirements and fire coder requirements (sprinkler systems) on new construction

Here is a little bonus story about a restraining order that I think you'll all find interesting.We had a tenant in one unit of a duplex assault a tenant in the other unit.

I put all of their names on 1 lease, though give them the option to pay their portion separately, always take 1.5 months security because college students love banging counter tops, throwing beer bottles, and tossing each other into walls after 2 shots of gin.Students typically get their refund check end Sept-ish, I give them an option to pay Fall semester Sept-Dec (4 months) and spring semester Jan- May (5 Months)  up front, with no discount. 

I apologize up front if this post is disorganized, but I'm sure there are other people who are or have been in my shoes and can offer guidance.About me: mid-30s, high-paying day job, telecommute and somewhat flexible hours, married with kids, own a duplex in Los Angeles county. 

We effectively turned our single family home into a duplex.

As such, in an effort to satisfy my own curiosity, is it ridiculous for me to consider cross-collateralizing two vehicles to secure a loan and get started with a house-hackable duplex or other small investment property?

When comparing (CMA) multifamilies, for example a duplex, do you compare them to other duplexes?
