I am new to real estate investing and currently own 2 condos and a three family home.

Check local regulations.First, verify that your local zoning laws, HOA rules, or condo bylaws permit renting your property.2.

My expertise is in the fix and flip space and now, I'm heavy into ground-up, new construction of DUPLEXES and Build 2 Rent (B2R).

And, you cannot change the property characteristics later.For example, suppose you bought a one-bedroom condo in Las Vegas because it was inexpensive.

I am only interested in duplexes in a defined area.

While I’m based in California, I’m looking to begin house hacking a duplex, triplex, or quadplex in Houston, Texas, and build from there.I’m looking forward to continuing to learn, becoming a property owner, and taking full control of my time and life to eventually quit my 9-to-5.

You could even househack a duplex or multifamily property. 

Question regarding Internet services for a Duplex.  

@Shannon Brill I think you might be overthinking this for a duplex.

DSCR Loans can finance property types that conventional loans cannot (non-warrantable condos, condotels, unique properties or mixed use properties...)Jay was going to say those things as other Ifs i am pretty sure!
