Credit hacks dissected: Do these {actually work}?

My buddy Alan sent me {a contact} with some interesting {charge card} hacks:

“1) {In case you have|For those who have|When you have|Should you have} {a brief} {credit score} (like me), get your parents/grandparents {to include} you as a authorized user {on the} oldest {charge card} (you inherit their {credit score} length)
2) {In case you have|For those who have|When you have|Should you have} any blemishes {previously|during the past} ({just like a|such as a} single missed payment {when you initially} got your {charge card} in {senior high school}) dispute it {before} {creating a} car/house transaction because while that blemish is investigated, {it isn’t} counted against you for {1 month} (while they investigate it); if the investigation {will not} {make contact with} you within {1 month}, the blemish {is fully gone} permanently”

I {wished to} {look for} sure, {therefore i} asked another friend, Andy Jolls, {who’s} a former MyFico exec. His reply:

“{They are} things we called score gaming at myFICO.

FICO ’08 closed the loophole around authorized users to an extent. {Individuals were} using his method {number 1} {to include} users to {a person with} a strong {credit score} {to obtain the|to find the|to have the} score boost. FICO ’08 now checks {the chance} it’s {a genuine} auth. user [parent/grand parent, etc. ] {and can} {allow} scores intertwine. Yes, {it could} happen pretty quickly.

Number 2 {isn’t} true, company {must} {take it off} in {1 month} if it can’t verify it, {nonetheless it} does count against you while they investigate. Said another way, you {submit} your dispute on August 1, {the business} doesn’t {have to} update your score immediately {if they} {obtain the} dispute. {They will have} 30 days {to research} and respond.

Also, it’s not gone permanently. {this is exactly what} credit repair shops tout but that’s not right. Scenario: Aug 1, you mail the dispute, Sept 1, they {take away the} item {since they} haven’t heard back. Sept 16th, they get verification of the account, {so that they} add it {back}. {Seem sensible}? Sometimes, {it really is} removed permanently {since they} never hear back.”
