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.

While my intentions are to do the  aforementioned,  i also hope to accommodate as many longer term renters that are aspiring to to make my house(s) their "home.

And the service dogs are only included in a protected class as a reasonable accommodation for a disabled person - so the protected class is a disabled person.So, I don't see any problem with saying yes to one dog, or no to another dog, based on anything you want.  

The house actually is laid out where it can easily accommodate the 14, the halls are 4' wide, there are two stairways that are pretty open, the house has over 20 windows that open and are at a height so that someone could escape to the roof or onto the covered porch, ladders for throwing out a window, hard wired smoke detectors, etc.

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. 

Should I accommodate her?

I hope you didn't pay for this seminar.Companion animals fall under requests for reasonable accommodations, under the different discrimination laws.  

I've also really tried to be accommodating as she is a young business owner and I was hoping to be supportive.

If you have a lot of demand for properties, then the agent can be a little more selfish with her time, knowing she can show the house during an open house at lunch and get a few applicants.In a slower market, you would have to put in more time to do showings, and you would also have to accommodate the times people are willing to come and see the place.So, if you are in a slower market AND the agent isn't willing to accommodate an evening showing, then you know she isn't great.For what it's worth, when I have a new rental hit the market, I try to hold an open house for the first set of showings on a weekday from 4:30 - 5:30.  

@Rod Joseph same here same here - i think section 8 is a great way to accommodate folks that otherwise couldn't afford the places they rent / helps them / helps the landlord so all good.
