Yeah, I used to use the keyword tool back like 10 years ago when I ran a guitar supply company in college.

Rent rates are high because of other factors impacting supply and demand (the ultimate reason).

The temp split across the return and supply is 20 degrees, but it is not going to drop your house temperature 20 degrees.

Basically the house is finished it just needs the flooring, hvac and power supply and structural final.

this is a supply demand situation.. seems to be an over supply right at the moment.. rents will hit a equilibrium over time .Issue becomes these projects take so long start to finish.. that what you modeled when you went into the deal is not market conditions when your ready for occupancy.. this is happening in A class throughout the US .. in many markets east side of Portland for sure.. 

I'm surprised your agent is not supplying you with referrals.

If you buy for cash in an area like Sandusky you will lose capital since supply outstrips demand meaning you won't get any meaningful apperciation.

Turn off all the supply valves. 2.

If you are providing supplies, how will the inventory be managed?  

They only sell Carrier and Daikin, which are fancier than the currently installed Goodman unit.Is there any real savings to be had by purchasing the unit directly from an HVAC or plumbing supply house?
