At the moment, it seems that they are smoking weed consistently at night (either that or a very consistent smokey skunk is roaming the premises *insert eye roll) My question is: can I do anything to stop this obnoxious smell?

. :) I'm not sure what market you're in, but I would recommend that you search "REI Investor (insert your city name here)" in FB under the groups section.

Tenant:Reference is made to _____ [Insert matter referenced, e.g., your telephone call of January 1, 2019,} wherein you notified Landlord that you intend to unilaterally terminate the Lease covering 123 Main Street, Omaha, NB 34664 before its expiration date.

No contractor is going to insert that type of verbage into the contract they have you sign .

Only by inserting a fantasy data at some area, but that's "cooking the books", and obvious fallacy like saying landlords can "absorb" the added costs, absorb where?

If there are none, please insert If you'd be interested in going to one that we sponsor.

Right now they either have tile that easily gets moldy or outdated inserts from the 90's.

IN most states plumbing fixtures etc are stamped state approved from shower inserts to all other things.. 

Instead of a tub insert, do a tile surround (the price difference is a couple hundred bucks.) 

Once you move back, which is what @Justin Summers unfortunately did, you cannot use the exception and must prorate.Here is why the proration was inserted in the law.
