This guy, Allen Kaul is based in the Miami, FL area. He posts ads on Craigslist and other websites offering short term apartment rentals.  He also calls people who post Apartment/Room wanted ads and offers "his rentals".
Once you send him the deposit by PayPal he acts strange and becomes very difficult to get in touch with.
If you are lucky enough to get a property address from him, he will not show up there.  

*** DO NOT SEND YOU MONEY VIA PAYPAL - as they will not support you once you file a claim for a refund.  Check their policy on their own website - they only arbitrate in cases involving physical merchandise, not services or property rentals.

Again, do not do business with this guy, Allen Kaul.  He also goes by the name Ahn Kaul on his PayPal account.

This gentleman, Allen Kaul, replied to my ad.  He claimed he had a place available for rent.  I decided not to go with him after reading a dozen negative comments posted about him online.

I rented a unit from this [***] a while back. He is a slime. He does not bother cleaning the unit for you and its full of ants. Also be careful about a deposit because at the end, its very difficult to get it back from him or at least all of it. People on the board have issues with him too but he somehow finds a loophole in the system. His mailbride wife is a realtor so they know the little tricks. You also need to ask for a real receipt. He walks around with a blank receipt book that has no meaning behind it and shows no proof that anything was paid. Last I heard, he resides in Winston Towers but I know he owns run down properties at both the Sahara Motel and just off Collins in the 70s area.

I unfortunately ran into this A-HOLE on a hard to pay for trip tio visit my daughter who is attending JWU in N. Miami. I had my 6 y/o and my sister with me. I am a single mom from Mass and thought I found a cheaper unit that would be a place to basically sleep and be out for the day. OH MY GOD!! The PLASTIC windows were actually not even in the metal frames. My little girl was HORRIFIED!!!! We left immediately! Called Allen Kaul and insisted on my $$ back and he said NO!! Called the police and got NO SATIFICATION!! They HAVE NO POWER AT ALL!! This DUMP IS FILTHY AND [***] ROACH INFESTED!! I AM STILL APPAULED!! AND I AM STILL HERE SPENDING $$ I DO NOT HAVE AS THIS F-FACE HAS MY $$!! HIS KOREAN WIFE ANH DOES NOT REFUND $$!! WTF??? I AM NOT DONE WITH THIS PIECE OF S - - T YET!!! I WISH I HAD HIS CORRECT ADDRESS SO I COULD GO FOR A LITTLE VISIT!!IF YOU KNOW WHAT I MEAN?? PLEASE BEWARE!! DO NOT DO BUSINESS WITH THIS A-HOLE!!

I actually a few months ago ran into one of his ads in craiglist, and I called him up, I went to the place where he said he had a room to rent, the room was big, but it was dirty and very messy, it seemed like if the room hasn't been cleaned but months. also the ad wasn't offering the real deal. the ad aid it including everything but when you actually asked him it was only the room and the electricity was split and the rest that in the ad was included you had to get it yourself.

I found this online about him. After reading this, it will make you think twice before even considering this guy.
