Do you pay to have them next day aired?

Material depends on brand, seer (efficancy) location of unit. is there already a air conditioner?

The tenants are all lovely people, though they seem to be concerned about 1) the condition of the garage, 2) the fact that the windows all let in cold air (by the look of them, they're probably as old as the building) and 3) the lack of landlord response to their multiple other (small) concerns about the property.

If you do choose the REI route, if a crash happens have your son take a couple roommates for $400/month, Air BNB it for the summers when school is out, put up solar panels, figure something out. 

ive seen a few on air bnd and if done right it seems to be a money maker .

The increased/inflated supply of money leads to larger/higher prices - sort of like how increased air in a balloon leads to a larger balloons - as people can "afford" to borrow and therefore "afford" to pay more.On the other hand, there's not much money at all available to borrow to rent! 

@Naomi Bjerk yes this is an especially good strategy for vacation rentals, turn key rentals, Air BnB and commercial property. 

(*The marketing costs, and the commission splits, don't necessarily have to be split equaly between all team members...the trick is to make it a win-win).These numbers are plucked from thin air, but these are the types of things you'll want to keep track of to see if the ROI is there. 

I am Air Force veteran, separated early this year, live in San Jose.

The inspection has another discrepancy as it says baseboard heating in the house but it's actually a warm air system, so I'm starting to think he didn't look at the HVAC at all.
