The drawback is that increasing the rent comes with red-tape and the possibility that the rent will actually be LOWERED, if the market dictates it's too high. 

For instance, heat tape for pipes is really cheap. 

I'm planning on filling out a 3 day notice and personally delivering it, and if she is not home, then I will tape it to her door and take a photo. 

I draw the line on the 6th day when I tape a notice to their door about non payment.I don't play games.I'm not so broke that a couple of grand is gonna hurt.And I am no longer interested with working with that tenant.I don't have to worry about whether a lease is renewed or not, the tenant won't be behind or late in the first place.The only time I will give leeway is if a tenant has spoken to me before the rent is due, does not avoid me, answers my texts truthfully and had a track record of paying on time. 

I have seen others take some double sided sticky foam tape or similar and put in as a stabilizing piece.

How much would it cost just to hang drywall and tape the seams?

It's amazing what a note taped to the door stating, "PAY OR QUIT" will do to a lousy tenant. 

Set up no trespassing signs around the property, and ran some caution tape (mainly for effect).

Normal rates are 10% around my area.I personally think you could do this without any red tape for a friend on one house.

The tenant had taped over the unit to prevent mold exposure to herself and baby, and expressed her concern to the handyman to please use extreme caution when removing the unit, she even gave him garbage bags to bag it, because didn't want mold in the air.
