Modular Duplex - House Hack

[Taylor Fender]

I am just starting out, trying to acquire my first property. I have decided to go with the house hacking strategy. Last weekend while at a 4th of July party, I was bouncing my ideas off a few friends that had made some big money of real estate before the market crash, but no longer participate. He told me that I should look into modular duplexes. I did not even know these were in existence. I started researching them and they do not appear to be a bad idea for my market. I am not in the best market, so I will be relocating to about 25 minutes away to start my investing. I have estimated my annual ROI on this property to be around 7.5% - 8.5%. My thoughts are to accept a slightly lower ROI than desired in return for less headache, because I would own a new property that would not need any upfits for years to come. If this is successful, I would then repeat this process, owning 4 units, 2 of which will be new and 2 that are nearly new. Is this a solid strategy?
