Am I being scammed by this potential tenant?

[Hanan K.]

I have a 4 bdr apartment for rent, (lower westchester county ny)  not in a very desirable school district so finding the right tenant can be tough. We do accept section 8 but are very picky when it comes to choosing a tenant.

Yesterday I met up with a Woman and her two children and grandchild- a 22 year old man and a 14 year old girl, and a little boy--her son's child who was about 4 years old. She says they are all on her Section 8 voucher as dependents and that's why she is allowed a 4 bdr aprt. 

I just have a funny vibe from the whole family:

--the Mom didn't want me to run a credit/background check. she had one printed that she said a realtor had given her and she didn't want to spend the money again. I explained that we always run our own. 

-- first off the mother looks nothing like her drivers license pic

-- her license says she was born in 1967 and there is absolutely no way she is 48 or 49......she's closer to 60 if not older.

--also license says 5'7"---also not the case as I'm 5'7 and she had heels on yet I was still taller than her in flats.

-- the mother looks Irish/German and the two children look African American Mix. I myself am north African so the topic came up on what my background was..... and she started mentioning that her children were part spanish and then she said "I don't know what else but they're a big mix" I think it's strange that you don't know what you children's father's background is.

--they were just way toooo polite. As in -- as soon as I walked over both the 4 year old and the 14 year old came to be with their hand out to shake mine and introduce themselves. Somewhat unnatural as if planned or trained---I just don't know.

--the 22 year old son has submitted the credit check request (credit not bad but his income alone is too low to support the cost of the apartment). 

--The mother says she replied to the request for credit/background check--but my service says she has not submitted her request.

Any ideas...feedback?

I'm almost but not 100% sure she is not who she says she is.

Thanks so much in advance
