YES! IT IS A SCAM! i was looking for a place in lausanne, and i got this same email from peterrosvelt@yahoo.com:
Hello ,

my name is Peter Rosvelt and I am a retired electrical engineer at 65 years . I inherited the apartment in Rue du Bugnon 7 1005 Lausanne, from my sister Maria Rosvelt in 2007 but I never lived in that apartment because i am staying in Glasgow , Scotland for the past 30 years . I tried to sell the apartment but i couldn't obtain the price I was looking for so I decided together with my wife and daughter to rent it to some agreeable persons.
The apartment is exactly like you are seeing it in the photos , completely furnished, but I have the option to send all my furniture in a storage if you want to bring your own one ( no additional costs).
The rent for 1 month is 600 EURO (for the entire apartment) inclusive all utilities (water, the electricity, the Internet, the cable, parking etc).
The period of minimal rent is 2 months up to 5 years.
You can move in the apartment in the same day when you receive the keys. The only problem is that we cannot leave Scotland because we are too old to come and my daughter cannot leave her job . Maybe you have the possibility to come here to take the keys and in this way we can know each other better.
If you cannot come, you do not need to worry, I have done all arrangements to rent the apartment from here, with a british agency that will take care of the business for me (with no additional cost for you).
If we cannot meet face to face it is very important for me and my wife to see the persons who will rent the apartment at least on an webcam. So please add the Messenger address peterrosvelt@hotmail.com for a video conference . Also you can give me your telephone number so my daughter can call you if you want to discuss by phone.

My best regards ,
Peter Rosvelt

DON'T SEND HIM ANY MONEY!

best,
