So, nope, you don't have to fix something immediately, even if it's a habitability problem.http://www.floridabar.org/tfb/TFBConsum.nsf/0a92a6...There are no laws that say you have to provide any kind of accommodations for an animal.

Tenants also hate noise, and a new tenant might not be so accommodating with you banging around and using power tools, etc., as your current renter has been.Then, when you move out, you rent that unit at highest market rent you can, and raise your old tenant's rent after her year lease is up, maybe keeping it just a skotch under market, to keep her, if she's still worth keeping.

Your upfront purchase price should accommodate odd factors such as layout so that you can re-sell at an attractive price relative to other homes in the area.  

Apparently, there is a big need for Section 8 in the community and not enough units to accommodate the need.  

What other advice/strategies do you all have that will help us ease the transaction while accommodating all sides?
