I was going to have the Electric, Plumbing and Drains, Heating System, and Roof all inspected by independent contractors in their fields. 

Unless you've got an issue with the heating, plumbing or electrical systems no further discussion is needed. 

One dilemma we are pondering is whether we want to build the building using gas for heating or do we want to go all electric.

(That's what it was really designed for and I'll likely take some heat for even mention it. 

That's not a timeline, it's a sweet nothing of a promise to keep the heat off for another week. 3.

Urgent maintenance is: no heat in the winter.

Plus, by having ONLY the individuals that will be residing there sign the lease, if they invite any more people to move in to "help with rent" you could put in your lease that "x" amount per week per extra person staying longer than 2 weeks, that'll keep them from trying to hide more than your water supply can handle or your heat bill if you have heat included (I didn't pay attention to where you were located but I live in NH where heat is a big deal).Again, just my own personal opinion based off of my own renting experience.

When I went over to make sure the heat was on before the chill came through, I realized they had locked the glass storm door in the front of the house so my key wouldn't work there and I went to the side door and realized I had a Hillman/Kwikset key on my ring but that the deadbolt lock was a Schlage. 

Often these properties are unlivable without working heat or water.

Anyone find one of these ? 
Trulia USED TO have a great one but took it down for some reason (I got confirmation from their support team).  Neighborhood Scout is another one but not very detailed if you zoom in / out...
