Total $20k..The kicker- I just quit my job (yesterday in fact) in remodeling homes, where I was basically a laborer/apprentice.

so you know...basic rule in contracting, take the labor/materials...then double it to the customer.

Now labor costs and materials might increase over time doing in stages.If money is available today then maybe if you can get zero interest same as cash from the contracting company than might can do all at once.Windows for tenants are seen as a MAINTENANCE item and NOT an upgrade.

It is more about negotiation in general, anything from a transaction to labor to treaty.

There was less labor due to not having to tear off and dispose of existing shingles.The few steel roofs I have done in the past have held up very well.  

Joe Richardson, by contractor do you mean the guy actually doing the repairs or the turnkey property management?

My labor cost would be $150 to install plus the cost of the fan.Any other thoughts?

@Joe Crooks Congrats on your plan.  

My wife and I are spending Labor Day weekend in British Columbia and we've booked a small camper trailer through AirBNB that's parked on lakefront property.

If it's a 2 year contract, I would offer to pay for the materials and split the labor tab with them.
