You can legally deny someone for something like not filling out an application completely, especially after specifically requesting them to completely fill it out.The same can be said for requiring people to read an ad completely and not contact you unless they believed they met all of your requirements, etc. 

LOL.The locks - maybe a compromise is in order, where you can put in a good latch for the inside - like one of those hotel type metal hooks that are more solid than a chain, so she can crack open the door to talk to someone and still be safe? 

shop around for cheaper ironworks guys and get a quote. i would image they quote around $800 - $1000 for gating the 1 area between the walls. that should be in your budget and is better than framing in a cheapo lattice DIY gate.if i really wanted to splurge, i'd go with aluminum gate; around here socal many folks including me of amerasian diaspora seem to love the rich modern light silvery look and it imparts heaps of feng shui apparently; doesnt have the black metal bars jail look at all!

During rehab we hire a company which installs Steel Ventilated metal screens on door / windows.

Older models have a small metal plate mounted on the siding,In the State of Illinois, mobile homes are registered with the Department of Motor Vehicles (DMV) which is run by the Secretary of State's Office.

Maybe even try one with a gold (shiny or worn) frame (don't be afraid to mix metals!).

I love the idea of heated floors and I think you can put the heating coils under almost any type of flooring, even concrete.The overhead blower wouldn't be very efficient, as heat rises.  

Although the filter really hasn't helped as the thing is beating itself to death.What you can do if you know a friendly AC man is get a 'new' inside unit (if it's the inside coils).What AC guys will not tell you is that you can easily match inside units to outside units as long as they are same tonnage, same type, and same gas.

Slightly off topic but if you replace the supply lines of your toilets do not forget to use the braided metal lines on the Clothes Washers.
