We have been in the acquisition mode.

I feel that the house hack model is the best way to get into real estate investing.

One topic in the back of my mind is the landlord responsibility around issues of safety and negligence on the property.

Once you are through residence you'll be in a mode of earning way more money doing the doctor thang, so you could decide to go full-on in Medicine and leverage your higher earning potential there and buy "easy rentals", big apartment complexes, or partner with other people and get totally passive returns on your investment. 

In contrast, my LPs will likely get 6-8% IRR while getting their capital back (because even when market cap rates increase by 100 basis points, I can still sell my deal profitably).Investors love safety and being able to get their money back first, before they look at IRR.I have not lost money for my investors even during the Great Recession of 2008-2009 and investors love a good track record.Lastly, when I refinance and I return my investors their capital, I don't buy their equity out.

I always build in a significant profit margin which doubles as a safety net.

Is it because there is a safety issue with the property making it a hazard to enter?

BTW, if you don't want your doors broken down, and if local law allows, give keys to the police and post a notice that the police and fire department have been given keys to the outer door, for safety's sake - and if law allows in your area, to the inner doors, too. 

I wanted to see how good of a model I can make that prices mortgage notes.
