Will your Credit score of 623 hurt you for renting a house?
Yes. Considering the national average is 687, 623 denotes that
you are a high risk candidate. The landlord may do one of 2 things.
Either not rent to you at all, since rental homes are at a premium.
Or ask that you give them a very high security deposit to offset
the higher risk that they are taking on by renting to you. Fix your
credit score, get your score up to at least average, then go rent a
house.
