Sounds too good to be true. Maybe you should share this information with everyone, cause if its $0 down for $450 a month you just sold out your lot!
What I think this requires is TTL, 1st Month Payment, Doc fees etc. Probably equates to $2k-$3k down. With a selling price of invoice you might be able to get $450 a month. But with no money down you can't be at $450 a month for 36 months. Maybe my math is wrong, you can correct me. Just doesn't sound right.
