It gave the wife and I a reason to be there and had a great evening.

It could just a joist issue which isn't an expensive fix or something to worry about.Check the ceiling for brown spots as sign of a current or prior leaking room.Window units in house means there is an HVAC issue no matter the reason given by the owner. 

there is nothing wrong with it, most microwaves have that option and do not have to be vented out, even though as a contractor i prefer them to vent out. if the existing pipe already vents out, which it probably does if there is a pipe in the cabinet already. what you would have to do is unscrew the 2 or 3 screws in the top cabinet that screw down into the microwave ( if not there then there may be 2 bolts in the front of the unit behind the cover that have to be loosened) that will loosen the microwave, then its a matter of taking the screws out that hold the fan at the top back, pull the blower fan out and change the direction so that it faces up, screw the fan back to the unit and put the microwave back up and bolting it. check to make sure the fan connects to the duct work, if not, add a piece of sheet metal to connect and seal that joint. btw you may want to unplug the microwave before doing so, just for safety reasons.

Tenant A was stubborn and did not want to take the time to share actual calculations of the actual utility bills.To solve this issue of Tenant B not knowing how much to pay for utilities every month, I asked Tenant A and Tenant B for verbal agreement for an estimation of the utilities that Tenant B can pay per month, we all agreed on a monthly estimate that seemed reasonable. $60/per month for Tenant B.Tenant B agreed verbally on this, but ever since that agreement he still neglected to include the $60 as an estimate for utilities in addition to his rent.I can’t make him pay it, since I do not have the actual utility bills.

One of the main reasons being is that I'm planning on financing through FHA / 3.5% down.

Before the end of the month seems reasonable to me.Working with a tenant, especially if it is not a habitual offender to get their rent in instead of just immediately moving onto eviction just makes good business sense. 

Bend is a good place to purchase for many reasons, including restrictions on growth of the housing stock in the area. 

This is one reason I do not rent to applicants living away looking to move to my area.

The main reason being, they prefer to be where the action is, in urban areas close to the hottest juice bar or aqua-yoga studio.

I tend to analyze deals with a value add mentality (within reason of course), if the latter happens it's a bonus.
