I don't like the island sideways, and where you can only get to 3 sides.I'd make these changes:1. bigger doorway - remove the cabinet to the left of the range.2. face the fridge toward the range, rather than 'away from the living area'3. rotate the island and plonk it in the middle of the room, if possible, make it mobile and just have non-specific lighting - 4 recessed lights or something.Rotating the island makes it a work surface for the sink/range area.Have seating 'over hang' on the non-work side, and both ends.

You may just need to do some editing or even invest in some better photos... for instance a slight rotation of that photo might help- right now it looks like the roofline is slanting downward to the right just a bit.

A dirty filter restricts airflow and strains the equipment.If you want your tenants to change the filters, you're going to have to supply them.  

This is a really interesting question.Here is something I read on yahoo finance the other day....1/3 of someones income going to rent is considered a financial strain and a large amount of Americans are in this "financially strained" position1/2 of income going to rent is considered very financially strained and that there are also a large number of people in this situation.I would say 2x income is too low. 2.5 is the lowest I think I would consider on a high end rental.

Remember if your tenants are paying very high utility bills due to inefficient furnaces, it will put a strain on their ability to pay rent.

And sadly, too many Americans have now been indoctrinated into believing that that compromise can't happen any longer, as if some fundamental shift in the rotation of the Earth has made it so that working together for the good of the people is no longer an option.When Americans stop demanding compromise (because they are tricked into believing the other side is so misguided that no compromise is possible), that's when this country is doomed.I like to think we're not there yet, but reading some of these posts makes me wonder...

Probably not- so, it's likely that this will or could lead to, at the very least, a strained relationship with your tenant, which should be fine.

Don't wait for the feces to strike the rotating oscillator again before figuring out what to do.

I have found that buying these items in multiple and rotating them to a laundry service that charges by the pound has been the best solution.  

I have talked to several doctors who have traveled to this hospital from nearby cities for rotations and complain about having to travel back-and-forth every day.
