As parents, we spend years preparing our children for life — helping with homework, teaching them to drive, guiding them through college applications. But one area that often gets skipped in both schools and homes is financial literacy. Specifically, the kind that matters the moment they sign their first lease, apply for their first credit card, or move in with someone they barely know.
At TheMorGroup, we work with tenants and landlords every day. We see firsthand what happens when young adults enter the rental market without the foundational knowledge they need. This guide is for the parents who want to change that.
1. What is credit — and why does it matter?
Credit is simply a record of how reliably you borrow and repay money. That record becomes a score — a number between 300 and 850 — that follows your child for decades and affects nearly every major financial decision they will ever make.
A good credit score means access. Access to apartments, car loans, lower interest rates, and eventually, a mortgage. A poor credit score means closed doors, higher costs, and fewer options — often at the exact moment in life when options matter most.
The earlier your child understands this, the better positioned they will be.
2. What do they actually need credit for?
Most teenagers assume credit is only relevant when buying a car or a house. The reality is much sooner and much closer to home.
Renting an apartment is often the first time a young adult’s credit score is evaluated. Most landlords in Las Vegas require a minimum score between 600 and 650. Without established credit, your child may be denied housing — or forced to rely on a co-signer, which means you.
3. How to help your child build credit early
The good news is that building credit does not require debt. It requires strategy.
Add them as an authorized user on your credit card. Your payment history becomes part of their credit profile. They do not need to use the card — just being on the account builds their history. This is one of the fastest and lowest-risk ways to give them a head start.
Help them open a secured credit card. A secured card requires a cash deposit as collateral and functions like a regular credit card. Used responsibly — small purchases, paid in full every month — it builds a positive payment history within six to twelve months.
Teach them the 30% rule. Keeping balances below 30% of the card limit is one of the most impactful habits they can develop early. Make on-time payment non-negotiable. One missed payment can drop a score by 60 to 110 points. Set up autopay. Make it a rule, not a suggestion.
4. How to choose a roommate — and why it matters more than they think
At some point, your child will consider living with someone to split costs. This is a reasonable and often necessary decision. What most young adults do not understand is that a bad roommate is not just an inconvenience — it can be a financial liability.
Teach them to evaluate a potential roommate the same way a landlord would. Ask these questions before signing anything together:
Do they have stable, verifiable income? A roommate who cannot consistently cover their share of rent puts your child at risk of eviction — regardless of who paid and who did not.
What is their rental history? Have they left previous landlords on good terms? A pattern of broken leases or disputes is a warning sign.
Can you have an honest conversation about money? Compatibility is not just about personality. It is about financial habits, expectations around shared expenses, and the ability to communicate when something is not working.
4.1 How a roommate can affect your child’s credit score
This is the part most parents do not know.
If your child and a roommate are both on the lease and the roommate stops paying rent, the landlord can pursue both parties for the full amount. If the debt goes to collections, it appears on your child’s credit report — not the roommate’s. Your child pays the price for someone else’s behavior.
Beyond the lease itself, shared utility accounts, joint credit applications, and co-signed agreements all create financial entanglement. What one person does affects the other.
The lesson is simple: who your child lives with is a financial decision, not just a social one.
4.2 What if they are stuck with a bad roommate?
It happens. Here is what they need to know.
Document everything in writing. Any agreement about shared expenses, utilities, or responsibilities should be written down and signed by both parties.
Know what the lease says. Most leases have clauses about subletting, additional occupants, and early termination. Understanding these terms before a conflict arises is far better than discovering them during one.
Communicate directly and early. Most roommate disputes escalate because small issues are ignored until they become large ones. Teach your child to address problems directly and professionally — not through passive aggression or avoidance.
Know when to involve the landlord. If a roommate is consistently not paying their share or violating lease terms, the landlord needs to know.
5. How does all of this connect to buying a home one day
Every good financial habit your child builds today compounds over time. A credit score built carefully through their twenties positions them to qualify for a mortgage in their thirties — with better rates, better terms, and more buying power.
The conversation is worth having now.
