Tenants are typically responsible for all utilities (water/sewer/garbage/power/gas) for single family homes. 

Did you design and pick out all fixtures/finishes/cabinets/tile work?

I would pick up some cash and use the proceeds to buy another property.  

Similar apartments nearby are around $2000 a month, but they aren't like ours- ours is a top floor corner unit, hardwood floors, new appliances, overall it's much nicer than other ones, plus utilities are included, unlike other places.

Also if you are coliving with your tenant, make sure you clearly write out what the responsibility of the tenants are (who takes care of the yard, common areas, utilities, etc.)

My suggestion - pick up Garret Sutton's book: How to use LLC's and LP's - here's a link: https://www.amazon.com/How-Limited-Liability-Compa...

I have a question in regards to HML and utilizing it to get a triplex under contract using a "cash offer" as the owner is looking for a strong cash offer. 

And since we are learning about construction, being able to go after work and measure cabinets for the 4th time, or compare the tile to the grout, or pick up supplies so your expensive contractor doesn't have to waste his time picking out paint colors, flooring, appliance etc... are all things that are easier to do in person.If you have a lot of experience flipping houses, or working construction,  then yes go for it, you can be successful as a long distance landlord. 

See https://www.biggerpockets.com/forums/432/topics/21...I also see no utilities, unless they are lumped into garbage.

Think about things like utilities, insurance, interest, taxes, typical consessions (seller paid closing costs for retail buyers), commissions, etc. - those things add up.
