I don't think this sounds likely. In Rudy Guede's other encounters he tried to LEAVE. He only pulled out the knife on Christian Tramantano when he found the door locked - when he was trapped. I think it's more likely that Rudy heard Meredith come home and go to her bedroom while on the toilet. He got up and tried to leave but found the door locked. Meredith heard the noise and poked her head around the corner and then he came after her because she recognized him or yelled at him.
Or maybe he came to her bedroom to demand the keys and the confrontation began.
If he tried the door first she would have heard him. Otherwise he could have just tried to sneak back out the window unnoticed.

So many LONEWOLF/ INTERRUPTED BURGLARY scenarios assume that Rudy was trapped in the cottage with no key to unlock the front door. Three considerations suggest otherwise...
1. Why is there no mention in the Massei Report---or any other Court Document I'm familiar with---of this predicament in exiting the locked front door, unless, of course, one were one of the girls residing at the cottage, and so in possession of a key?
2. Wouldn't common sense suggest that the girls would have left an extra key---a
convenience key--- in the interior door lock, or hanging from a key rack next to the front door, as a matter of convenience? Otherwise, to open the front door from the interior, one would have to find one's purse to grab the key every time a visitor came calling, every time one took out the trash, etc.
3. In Amanda's famous email she seems to suggest that there was such an extra key...
"so i arrived home and the first abnormal thing i noticed was the door
was wide open. here's the thingabout the door to our house: its
broken, in such a way that you have to use the keys to keep it closed.
if we dont have the door locked, it is really easy for the wond to
blow the door open, and so,
my roommates and i always have the door
locked unless we are running really quickley to bring the garbage out
or to get something from the neighbors who live below us.... anyway, so
the door was wide open. strange, yes, but not so strange that i really
thought anything about it. i assumed someone in the house was doing
exactly what i just said, taking out the trash or talking really
uickley to the neighbors downstairs.
so i closed the door behind me
but i didnt lock it, assuming that the person who left the door open
would like to come back in."
Notice that Amanda here implies that the person had used some key to unlock the door and that person didn't take that key with her. Therefore, that key must have been left in the interior lock or hung on the key rack, when the person exited the front door. And yet if this had been a personal key owned by one of the girls---and so would have been on a distinctive key ring---wouldn't Amanda have been able to say which girl had just left the cottage? Or, at least, know that it was one of the girls that had just left? But Amanda doesn't know which girl had left, and she can't be certain that it was one of those girls. In closing the front door, the interior lock and the key rack would have been clearly visible to Amanda, so it seems that what she saw left behind was a single extra key---an anonymous key--- kept there by the girls for convenience.
