Loan Estimates and rent vs buy, explained like you're 5
The parts of a Loan Estimate in plain words, how to compare two lenders' offers step by step, and the costs of owning that a monthly payment leaves out. It never picks a lender, a loan, or renting or buying.
Explain it like I'm 5
A Loan Estimate is the standard form each lender gives a person who applies for a mortgage. It puts the important loan details in the same places, like two grocery lists made in the same format. That lets you compare offers from different lenders side by side. Ask each lender's loan officer or a HUD-approved housing counselor about differences that fit your situation.
This explains. It does not advise.
Where all four AIs agree is the solid ground. Where they disagree is exactly what to ask each lender's loan officer or a HUD-approved housing counselor. This guide never names or recommends a lender or a loan, or says whether to rent or buy.

What to compare, part by part
Five parts of a Loan Estimate, in the order you meet them on the form, then renting against owning.
Loan terms
This part shows the loan amount, interest rate, and monthly principal and interest payment. Principal is the amount borrowed, and interest is the cost of borrowing. It also shows whether any of these can go up, and whether there is a prepayment penalty, a charge for paying early, or a balloon payment, one large final payment.
What to compare
- Compare the loan amount, interest rate, and monthly principal and interest payment.
- Check whether the rate, amount, or payment can change after closing.
- Compare any prepayment penalty, balloon payment, and rate lock, which holds the rate for an agreed period.
What can mislead
- A lower starting payment may rise later if the rate or loan features can change.
- An unlocked rate can change before closing, so ask each lender's loan officer about the rate lock.
- Different loan types or terms can make a side by side comparison misleading.
Projected payments
This part estimates the total monthly payment over the life of the loan, including principal, interest, mortgage insurance, and estimated property taxes and homeowners insurance. An escrow account is an account used to collect money for some bills and pay them when due. The form shows whether taxes and insurance are paid through escrow.
What to compare
- Compare the total payment during every period shown, not only principal and interest.
- Compare mortgage insurance and the estimated taxes and homeowners insurance.
- Check which bills are paid through escrow and which you pay separately.
What can mislead
- Taxes and insurance can change, even when the loan payment itself does not.
- Bills outside escrow are still owed and can arrive separately.
- Association dues may not be included in the projected loan payment.
Closing costs
This part divides upfront costs into loan costs and other costs. Loan costs include origination charges, services you cannot shop for, and services you can shop for. Other costs include taxes and government fees, prepaids, such as bills paid ahead, and the initial escrow payment. Points are upfront charges that can lower the interest rate.
What to compare
- Compare origination charges for matching loan offers.
- Compare services you cannot shop for with services you can shop for.
- Compare taxes and government fees, prepaids, initial escrow, points, and total closing costs.
What can mislead
- Estimates for taxes, insurance, and some services can differ without showing a lender advantage.
- Points require more money upfront and can affect the rate and later payments.
- A lower closing cost can be connected with a higher rate or other loan cost.
Cash to close
Cash to close is the estimated money brought to closing. It is worked out from closing costs and the down payment, with any deposit already paid and lender credits subtracted. Lender credits are money from the lender that lowers closing costs and may be connected with a higher interest rate.
What to compare
- Compare how each estimate calculates cash to close from the same assumptions.
- Check that the down payment and deposit already paid are shown correctly.
- Compare lender credits with the related rate, payment, and total loan costs.
What can mislead
- Cash to close is not the same as closing costs because it also reflects the down payment and credits.
- A missing deposit can make the amount look too high.
- Lower cash to close can come with higher later borrowing costs, so ask each lender's loan officer.
The comparisons section
The last page gives figures for lining up two offers. It shows what the loan costs over the first years, the annual percentage rate, or APR, and the total interest percentage. APR combines the interest rate with some loan costs as a yearly measure, while total interest percentage compares scheduled interest with the loan amount.
What to compare
- Compare the early-years cost and the amount of principal paid down.
- Compare APR for loan offers with the same type and term.
- Compare total interest percentage when the loan amounts, types, and terms match.
What can mislead
- APR is not the same as the interest rate and includes some fees.
- The early-years comparison may not fit if you move or refinance sooner or later.
- A changing rate can make future costs differ from the figures shown.
Renting or buying
Renting and owning involve different costs and responsibilities. A monthly loan payment leaves out upkeep and repairs, homeowners association dues, utilities a landlord may now pay, and the costs of selling later. How long a person expects to stay matters, and the reader's own documents, finances, and situation determine the comparison.
What to compare
- Compare rent with the full monthly cost of owning, not only the loan payment.
- Include upkeep, repairs, homeowners association dues, utilities, and later selling costs.
- Weigh the cash needed upfront and how long you expect to stay.
What can mislead
- A mortgage payment alone understates the cost of owning.
- Rent may include repairs or utilities that a homeowner must pay separately.
- Selling later can involve costs and may not fit a short stay.
Rules to know
- When you get a Loan Estimate
- The lender must give you a Loan Estimate within three business days of receiving your mortgage application. Every lender uses the same standard three-page form, and getting one does not mean the loan is approved. Reverse mortgages and home equity lines of credit come with other disclosures instead.

- What a lender can charge before you decide
- Before you get a Loan Estimate, the only fee a lender can ask you to pay is a fee for your credit report. It can charge other fees, such as an application or appraisal fee, only after you get the Loan Estimate and tell it you want to proceed.

- How long a Loan Estimate holds
- The lender only has to honor the terms of a Loan Estimate for 10 business days. Tell it within that time if you want to proceed; after that it can revise the terms and costs. Saying nothing never counts as going ahead.

- When you get the Closing Disclosure
- The lender must give you the Closing Disclosure, a five-page form with the final loan terms and costs, at least three business days before you close, so you can compare it with your Loan Estimate and ask questions.

How to compare two Loan Estimates, step by step
- Make sure both estimates are for the same loan amount, loan type, and loan term.
- Compare loan terms, including the rate, payment changes, prepayment penalty, balloon payment, and rate lock.
- Compare projected payments, mortgage insurance, taxes, homeowners insurance, and escrow treatment.
- Compare loan costs, other closing costs, lender credits, and estimated cash to close.
- Compare the last-page figures for early-years cost, APR, and total interest percentage.
- Ask each lender's loan officer to explain differences, then ask a HUD-approved housing counselor about renting and owning costs.
Common mistakes
- Comparing different loan amounts, types, or terms can hide the real reasons payments and costs differ.
- Looking only at the monthly payment can miss mortgage insurance, taxes, insurance, closing costs, and association dues.
- Treating estimated taxes or insurance as fixed can leave you unprepared when those bills change.
- Assuming a rate is guaranteed when it is not locked can change the later cost of the loan.
- Forgetting upkeep, repairs, utilities, association dues, and selling costs can understate the cost of owning.
- Ignoring how long you expect to stay can distort the effect of upfront and selling costs.
Questions to ask each lender
Ask each lender's loan officer or a HUD-approved housing counselor.
- Are both estimates based on the same loan amount, type, and term?
- Is this rate locked, and which rate, amount, or payment features can change?
- Does this loan have a prepayment penalty or balloon payment?
- How did you calculate the taxes, homeowners insurance, and escrow amounts?
- How do the lender credits, deposit, down payment, and closing costs produce this cash to close?
- Can you explain the differences between these offers, and can a HUD-approved housing counselor review my rent and ownership costs?
