I am quite a hothead myself and this tenant was a wimpy 4-/1/2 foot 85 pound Asian, but I actually smiled and asked the tenant when he was going to move.

I go through about two pounds of raw sausage a day and almost as much cappy (just on the weekends, however).

Pound in some tall stakes, and run several lengths of stringline at 1', 2' and 3' off the ground and you've got an instant fence. 

U.S. building codes specify a uniform live load of 40 pounds per square foot (psf) for most residential floor designs.

And when it comes to HVAC , they will deny and still charge you $80+ per pound of Freon .

Such as no dog over 20 pounds adult weight.

Now there are features and benefits that need to be accounted for when placing a value on the property, and also the price per pound discount for buying larger units, but at the end of the day you can use the small "units" to get an idea of economic value (average price per unit based on CAP) for the larger building you are looking at rehabbing.

Before rent control I got rid of undesired tenants by raising rent above market and tenant would give notice.  

Do I now allow her to stay without a lease for an extra 1.5 months or do I tell her to pound sand, rerent it for more, and move on? 

Admittedly, I stopped reading this thread several posts back .... but personally, I would tell the tenant " to go pound sand!
