You can run the math and see for yourself, all cash will always mean a lower ROI.

You can go through the math you used to arrive at that number, but you don't have to.

My math might be off, assumptions also.

I did my math and the real number is closer to 8%.  

Of course less any other improvement costs you have put into it since the LLC took ownership.I did the opposite of you, where I sold an LLC asset to myself, and the math worked out for me as mentioned above.  

 For a first time investor, i don't believe i would recommend investing in a lower end rental. if you mean by lower end, a D class property. a lot of times the tenants that can attract can be problematic, and if you are not use to handling that it could bring you down and turn you off from investing further. search out a property in a decent maybe up and coming area, one in an area where it looks like people take care of their homes. do all your math and homework to find out all your expenses and what the average rent is for the area for the same size rental. i would recommend joining your local associations, you could meet some contacts there and learn from them about areas.

You would have to do the math on the rental fee, but a decent high efficiency furnace for the average 1200 sq/ft home should only run about 3000-4000 dollars and they last approx 12-15 years.

In terms of the house hacking route, I really want to emphasize how new I am to this so as I read your response, I could somewhat understand the math and your explanation behind it but I'm still a little lost on your explanation so I hope you don't mind if I pick your brain some more!

(Not disclosing that only a full price offer could close quickly is deceptive - which is unethical)Someone suggested I was potentially angry, I'm not, it's a math problem plain and simple.

My math says you're behind by $90k...not to mention the compounding effect based on how many times you could have reinvested that same $150k in REI.What's the word I'm looking for here,...uhhh....Bammm?!
