Before you spend any money, you just need to price everything out (i.e. cost of homes, moving costs, installation, hook ups such as electrical, water, etc). 

If you're running plumbing, electrical, HVAC out there it's different than if you're just putting up drywall.

Taking some of that space for the bedroom would only require framing in a non-load-bearing wall, closet, and bedroom door, plus adding a few electrical outlets/switches, and then finishing with insulation, drywall, paint, and trim. 

Also not to add electric because we have different standards.

What seems to unique to the area (at least on a large scale) is electrical theft.You should also know about "Electrical Theft" in the Big D.Renters get electric shut off and pay someone to make an illegal hookup.Using fish hooks or other unsafe methods, WXYZ Reports: https://www.youtube.com/watch?

If you talk to engineers and AI companies that also build robots they say the very complex tasks are many. many decades away from semi-automation.

But any plumbing or electrical I don’t know what’s code 

You'd have to play with the search engine on zillow to find them.As for the 650k price, that's specifically for my neighborhood.

I am house hacking my 1st SFH rn and none of them have rental insurance but I do manage the utilities because I live with them so I ask them for their part of the bills/utilities...I will probably take my name off the utilities once I move out and make the primary tenant get the water/electric in their name...

i would check with the architect/engineer for the most accurate information
