House Hack in Denver

[J.R. Gutierrez]

I'll preface this by saying this is mostly hypothetical. Unless I found a lender or someone willing to partner with me on this, it's more of a study than anything. So here it is:

I found a listing for a Fourplex in Denver. The property consists of three 1 bedroom/1 bath apartments in a building upfront and a 2 bedroom/1 bath single family home on the back of the property. There is also a 1 car garage in the back. From the photos and a Google Maps search, the property and area seem to be in relatively good shape. The property is listed for $700K. I did a Zillow search to check what similar units rent for in the area and actually found one of the 1bd units listed for $1,200/mo. So 3 x $1,200 = $3,600/mo for the three apartments and an additional $1,500/mo(?) for the house in the back. Plus something for the garage?

Hypothetically: I would live in the less desireable of the units (probably the basement apartment) and rent out the rest, including the garage to whichever unit wanted to rent it.

So here are my questions based on the simple information I gave:

1. Is there value to this property in regards to house hacking?

2. Are my rent figures off or in the ballpark?

3. How much would one expect to spend a month on mortgage, taxes, etc?

I've only been on BiggerPockets for less than two weeks and I'm pretty much new to REI. I've been learning a lot and I think simple exercises like these will help me understanding the business better. I'm sure some of you will point out information I've missed that would affect this as an investment.

Thank you in advance for the help!
