Does each unit have separate meters for utilities?

The typical calculators don't account for the fact that I need to live somewhere, would be paying holding costs such as utilities anyways, or that I won't be paying taxes on the gain (Yay owner occupant!). 

I'm 20 years old, work full time for a utility company in New York, and am very interested in starting to invest now, while time is on my side.

It's been a few days since we close and so far, I haven't moved utilities like gas, electric,w ater over to my name and it's still in the seller's name.

Or you think they own them but when it breaks they say you have to fix it because it came with the place) and stuff like who pays what utilities, is their parking and if so is it assigned and all that kind of stuff.  

I have done all this with No money down because I used some of my VA loan and I had 2 roommates the entire time I lived in this 1,900 square foot house and that covered the mortgage and the utilities.

All other expenses pale in comparison when you have no tenant and the unit is costing you money every month (even if it's free and clear because you still need to pay taxes, insurance and some utilities specially in the winter).

I am looking into wholesaling in the Dallas, TX area and wanted to introduce myself to all buyers that are either just starting out and looking for deals and also existing investors that are willing to partner up with me in my venture to becoming a top performer in wholesale industry.I have been utilizing BP for a year or so now, gaining knowledge from past forums, but it's time too put what I've learned to use and get too work!

Question: How can I control the property & keep the exiting HELOC in place but prevent the seller from utilizing additional credit from the HELOC?

Because my parents and I lived in the same building I left approximately 1,100 sq ft open that both families could utilize.
