After that, I had one of the no-shows ask for another appointment.  

When this happens I make $75.00 for a few hours of walkthroughs with the turnover crew (before/during/after) and can expect another $400 for leasing the property after 5 round trips and 17 showings which total 10+ hours after driving time (don't forget to add another 10+ hours for putting together the listing, scheduling appointments, calls, emails, application screening, more emails, phone calls to previous landlords, the Lease-signing appointment, etc).

The conservators can be court appointed and handle the finances for multiple disabled people including receiving and dispersing social security or VA income.

For the rest, I'd make an appointment for them to see the unit, letting them know that the first approved tenant who actually signed a contract and paid the security deposit got the apartment  & that I kept showing the unit until that is what I had.And if they were late (without a call with a dang good reason like they're stuck in bumper to bumper traffic, which I could verify on Google maps) or didn't show, they were denied.  

(a) If the owner's interest in the premises is terminated by sale, assignment, death, appointment of a receiver, bankruptcy, or otherwise, the new owner is liable for the return of security deposits according to this subchapter from the date title to the premises is acquired.

They've only been in the house for 6 months and have consistently tried to pay late every month (I have insisted on on-time rental payments, and they have complied, but grudgingly), brought a dog in despite a "no pets" policy, and are generally stand-offish (the first thing they did when they moved in was install a security system, and when I come by the house even with an appointment, they call me while I'm on the front steps and say that they're not in the house). 

For example, I set 7 appointments last night to show an apartment that I have coming available next month. 3 of them never showed up & one called to say that he wasn't able to make it. 

Once I have a date set I call people and make "appointments" for half hour time slots. 

Other than for appointments I never tell tenants when I'll be there (could be 6 am or 11pm). 

Took about 6 showing appointments before I got one.
