So how do you score and weight the categories to ultimately reach the score?

In self employed situations we more heavily weight credit and when in doubt we just ask for more security. 

@Martin Thomas if their income is right on the borderline of what you normally accept, then I would more heavily weight their credit.

And add the 3rd room can be used as bedroom or den, but is big enough for a queen sized bed.And I'd add to the dog weight 50 lbs "adult" weight - just to cover the sneaky ones lying about the age of their dog.Maybe you can put in your search terms the name of the university, so when they do searches for rentals by such and such university, it will show up.  

The sheer magnitude of information stored there actually added half a gram of weight to my PC.Would much prefer the interaction available here on a more recent post.

(Before you've dug and poured your sixth hole the first poured hole is nearly ready to accept weight) *Build your new girders with glue/screws/ 1/2" plywood sandwiched 2x10's (will NEVER sag, plywood mandatory, emphasis on the word "mandatory").

The space feels much larger with the white cabinets and lighter colored floors.  

Great tenants are worth their weight in gold!

It takes a lot of force to do this with some weight behind it - unless it was already loose or bolts were not properly securing the toilet base to  the floor. 

My last unit was a lighter tone.Brown, tan, rented!!
