This is no different than a baker using $1 of ingredients to make and sell a $4 chocolate chip cookie.You can only flip so many houses, so the ability to scale is based on your time and energy.

I want to at least get the electric done but hoping to get water and gas too.

Additionally, study and learn as much as you can about everything related to construction/building and the ins and outs of RE....As a 16 yr old, you have the time and energy to get a lot of knowledge under your belt, which will be a huge advantage for you over your competition....

Water bills are insane here ($220+ for 2 people with minimal outdoor watering), so all in with internet, gas, trash and electricity that's roughly $500 month.

Each state is different, and many brokerages also have their own guide lines, so consult with your broker before you spend a dime and before you spend any more mental energy brainstorming the perfect name.

Take the same lesson and apply it to the Hvac, roof, foundation, electrical, etc.  

Re-insulated all the walls, new drywall, all new electrical, new 200A panel, all new plumbing, new water heater.

I think what's more important than anything else, is that you go into this meeting very self-aware of the fact that you're 15 years old, you have no life experience, and you have basically nothing to offer this man.There is no amount of time, energy, or effort that will add value to his business at this point.

Added central AC, fencing, updated electrical, better drainage, landscaping and flooring.

Basically everything is new; roof, siding, windows, electric, plumbing, HVAC, kitchens, bath, flooring etc.
