I have a duplex with 3 beds 1 bath per side. 4 adults, 4 youth and a infant and water runs over $100 per month. more when they don't hear the toilet running and forget to call me to fix it.

Quieter neighborhood, closer to work, many other legit reasons of why I am moving - besides the fact of saying "I want to move because I am an adult and house hacking / building a multi fam portfolio while doing so is awesome!"

An adult son and father will be living in the unit.

An overlay zoning resolution was passed some years ago around several of the universities in Philadelphia regarding the number of unrelated adults who can occupy a house.  

Thieves look for the red tag on the meter and then they go in and strip the home.Our average tenant timeframe in those areas were about 8-9 months and double the staff time to deal with all their issues of month to month life, so from my experience unless you want another job of adult daycare those are the things you are going get coming down your funnel of fun.We ended up selling all of ours in that area and we do not even manage them because it was just too time intensive and problematic.I have done many speech's and had many conversations with investors about when I did "My Time" in the South-East.

I don't know electricity rates in your area, but I think for 8 adults with their own electronics plugged in, $200 would be more realistic.Sounds like a good deal though!

My focus is on Luxury Properties, Golf Course Subdivisions, 55+ Active Adult Communities and of course investing with both rehab and flip, as well as rehab and hold strategies.

I'm no attourney, but I don't let anyone live in one of my units unless I have them on the lease; adults or children.

@Eamon SullivanFirst issue you will run into will be a local by-law or ordinance limiting the number of unrelated adults permitted to live in a single dwelling unit - very common in university towns.    

I've flown professionally most of my adult life and had a lot of fun and a lot of "interesting" moments, ingredients which make me much more tempered these days.
