Security deposit up front only option?

[Ryan Billingsley]

We have a potential renter who is offering to pay 100 dollars more per month for the 1st six months until the security deposit is paid.  She is currently staying in a extended stay for $250 per week.  She said she found another property to move into but it was rented out from under her.  Our property is a 1/1 but has a extra room that could be used as a bedroom.  She has a 17 year old daughter that will be living with her.  Also she has a couple kids in college.  Is this a normal offer to let a renter pay the security deposit over the first 6 months instead of all up front?  We were thinking about making it nonrefundable to allow her to do that.  The property is in a C class neighborhood so it is not the best quality tenants interested in renting.
