Any other ideas to stop this other then adding to the house rules/ sticking a label with instructions not to turnoff any equipment?

Make sure you call the title company to get wire transfer instructions (NEVER GO OFF OF AN EMAIL).

But have also been researching the possibility of purchasing a manufactured home and then selling.  

Plumber installing and, so far, 4 meters are leaking through the epoxy between the connections.Hoping it is just these valves and not the manufacturing all together.

I would only spend money paying them down if instructed to do so.3.

Give her 5 days (or whatever your state allows) to CURE this manufactured chaos by having the non-lease holder vacate.

It will have to be the same manufacturer as the “furnace” that is inside the house unless you plan to replace the whole thing.

I have not done one yet, but I have talked to a manufacturer. 

But they should be able to explain all these things to you, in a "neutral" manner, giving you the good and bad things of each type or each brand.There are 7 manufactures of shingles, mostly here in the US, and one (Iko) in Canada. 

The concrete manufacture has said it will price its precasts weekly.
