Based on layout, this house seems like it would work better as an adult family home or possibly rent by the room. 

Put pad locks on crawl space access doors or else copper pipe and wiring can get away.Also the locks on attic doors and crawl spaces will keep curious children from playing in those off limit areas, as well as adults who don't have a need to be in there.

Ok, so I'm not really breaking even.I got into this rental situation because we had an opportunity to purchase an immaculate foreclosure, and needed to cover the mortgage on our previous home.I am hoping to start purchasing some buy and hold properties, that I can rent to start building some cash flow, to invest back into real estate and grow my portfolio, to ensure a comfortable retirement, and to teach my 3 daughter's how to create cash extra cash flow, for their adult lives.I am currently a full time Cybersecurity engineer, and would really like to figure out how to make some of this happen by converting my employer held 401k into a Sole 401k, that I can invest in rental properties with.Other than this rental (and a very similar situation 10 years ago), I am new to real estate investing.

As an adult, I’ve also lived in Seattle, Washington where the summer months are awesome.I wish I could remember how the real estate ‘fire’ started within me, but I can’t remember.

@Peter Chesterand @Shane Pearlman,Like @Minh Le and @Jeff Greenberg, all my partnerships have been 50/50 equity ownership with a single other partner (Technically, my partner and their spouse - both male and female.)

Tell her to move out.. or be adult about it and live in house / divided until this get's figured out.MESSY. 

Most adults lack the ability to pay attention or take heed to financial advice, much less a group of children, a majority of which think they know it all already.  

No adults in the home that aren't on the lease, turns into an out of luck family member needing a place to stay short term, turns into 17 people in a 3 bedroom home)

Jose Duque Devil's Advocate: Have you account for the increased wear and tear of having 6 full-sized adults in a house?

I am a pet owner and animal lover myself, and I would hate to have to give up one of my pets as they are like family, but sometimes adults have to make adult decisions
