Similar condition, square footage, bed/bath count, etc. 

@Josh Young We're looking at San Tan Valley and the Eastside of Queen Creek.

.: @Marcus AuerbachThe thing I always think about when I look at the homes along the golf courses is how much I really don't want to know what goes on in them. main thing I look at is why the heck would they buy one 180 to 200 yards off the tee box right where golfers are going to slice or hook into their house break windows and then walk through your flower beds to find their lost ball...

Heads in beds is physical.

They are a summer weight comforter and these are a bit thinner that those.Overall they are a larger size than your typical Walmart/Target comforter so they will hang nice on the bed and work great as a summer weight cover.

Eg before the sun comes up (or when she goes to bed), closing all curtains or blinds in the east and south facing windows (and later on the west facing ones) to keep the sun out; opening windows once it has cooled down at night and early in the morning (eg before 8 am)? 

With this option, we're wondering if it's better to offer it as a 3 bed 1.5 bath with 2 bonus rooms (which we live out of), or rework one of the rooms into an actual bedroom to make it a 4 bed.With either option, we're also wondering if it's best to have the cashflow of our current house to offset any unexpected expenses, or if we should pay extra and try to pay off our current house as soon as possible.

Has anyone had any experience with a Murphy Bed?

If you have a pretty place that's furnished nicely, you can rent to students for more than $1100/bed, which can add up for large, older homes with many bedrooms.

Examples where this has been done successfully include bed and breakfasts, self storage properties needing 24 hour management presence  with living quarters.
