I think this is classified as a hosting issue.

I host Dead and Walking and players can join and everything works fine except houses don't save. It saves the fact that you own the house but any item you place in it disappears after a reboot. I have done everything that portfoward and byond help told me to. I have DMZ mode on. Every folder leading to the games files is turned off "read only" and Everyone has full control in it. Halp me please...
This is a programming issue than a hosting one.

You have to talk to the programmer of the game. While they may be saving the access to the house, the programmer left out a method to account for the products within the house itself as, likely than not, it is not in the mob's content list thus not directly saved when the mob itself is saved.
