You already know the lowest rate is not always the cheapest loan. What surprises most buyers is the next step: two lenders can quote you the exact same interest rate and still put thousands of dollars between their two closing tables. The rate is just one line on a three-page government form called the Loan Estimate, and every lender is required to use that form, so comparing lenders really is reading the same lines across three or four documents. Here is what to compare, line by line, with the numbers Peoria buyers are working with this month.
Reviewed October 12, 2026, with current Peoria numbers: the average 30-year fixed mortgage averaged 7.40% in Freddie Mac's survey released October 8, 2026, up from 7.28% the week before, and Peoria County's September 2026 median sale price was $175,000, down 1.4% from a year ago, per the RMLS Alliance Local Market Update. The worked examples below use a $140,000 loan, which is 20% down on a $175,000 home, rounded for illustration.
The same rate, very different loans
Two Loan Estimates, same loan amount, same program, same property, same rate, quoted a few days apart. The interest rates look identical, so it is tempting to think the loans are identical. They usually are not, and the difference hides in the fees, the credits, the APR, and the cash-to-close. Lenders price the same loan differently: one lender's going rate may simply cost more in fees, and another's may quietly include a lower rate, a credit, and a thinner bill at closing. Your job is not to rate-shop, it is to loan-shop, and the Loan Estimate is the tool the government built exactly for it.
Interest rate versus APR: the first screen
The interest rate on page one of the Loan Estimate is what your monthly principal and interest payment is built from. The APR, the number in smaller print next to it, is not the rate plus profit, it is the rate blended with certain loan costs folded in, expressed as an annual percentage, so it is the best first screen for a first pass. Two lenders quoting, say, 7.25% can show two different APRs, 7.38% and 7.51%, when one of them is charging points and the other is not. A lower APR at the same rate usually means lower fees, and a lower rate with a higher APR usually means the fees are being paid up front. The catch is that APR assumes you hold the loan the full 30 years, so it is the best first screen, never the last word, for a borrower who plans to move or refinance within a handful of years.
Page one also carries the payment, the closing costs, and the cash-to-close
Page one of the Loan Estimate shows the projected payments, including principal and interest, then estimated taxes and insurance, so you see the realistic total, not the teaser. It also carries the single most useful line on the whole form: cash to close. That is the total you must bring to the closing table, and it is the sum of the down payment, the closing costs, and any prepaids, minus any deposits, credits, or money you already put down. Two same-rate lenders can be a small fortune apart on this one line, and it is the number to circle first.
Section A on page two: origination and underwriting fees
Page two, Section A, is where loan costs live: origination, underwriting, processing, and application fees, plus any discount points. This is the section that varies most from lender to lender and the one most buyers skip, because the numbers are bland names for real money. The same rate can carry an origination fee of $1,250 at one lender and $2,950 at another, with underwriting layered on top, and that difference is pure cost. Add up the whole of Section A before comparing anything else, because it is the most controllable part of the comparison.
Discount points: paying a little now to pay less every month
A discount point is 1% of the loan amount, paid at closing to buy the rate down. On a $152,000 loan, one point is $1,520, and it typically buys the rate down about a quarter of a point, saving maybe $25 a month on the payment. The math to ask for is the break-even: if the point costs $1,520 and saves $25 a month, the break-even is near five years, meaning you come out ahead only if you still own the house long enough for the savings to catch the cost. Points are not bad, they are a prepayment, and they belong in the comparison only inside your time horizon.
Lender credits: the mirror image of points
A lender credit is the inverse: the lender charges you a higher rate in exchange for a credit toward your closing costs, reducing your cash-to-close. On the same $152,000 loan, a $1,000 lender credit is a real $1,000 off your bill at closing, showing up as a negative number in Section J, and it is worth roughly a quarter point of rate. That is the structure that makes sense when cash is short and the plan is to move or refinance within a few years, because the higher rate never gets a chance to outrun the credit. Always ask what a credit costs in rate, exactly, the way you ask what a point saves in rate.
Closing costs beyond Section A: title, appraisal, recording, and prepaids
Sections B through J cover the rest of the closing bill: title insurance, settlement fees, the appraisal, recording, and the prepaid taxes, interest, and escrow. Illinois closing costs commonly run 2% to 5% of the purchase price on top of the down payment, and the loan-related slice of that total can still vary by hundreds of dollars between lenders quoting identical rates. The title work belongs in the comparison too: even though the lender does not keep that money, lenders pair with different title companies, and the difference lands on your bill at closing.
Think of it as two questions in one: what does this loan cost me every month, and what does this loan cost me at the table? Cash-to-close answers the second one, the monthly payment answers the first, and the APR and the five-year cost on page three try to answer both at once.
The worked example: same rate, very different loans
Say you are buying the median-priced home in Peoria County, $175,000, with 20% down, a $140,000 loan, quoted in a market where the average 30-year fixed sits at 7.28%. Lender A and Lender B both quote you 7.28%, no points. Lender A shows $1,250 in origination and underwriting; Lender B shows $2,950, plus a $750 processing fee and title work quoted about $400 higher. Identical rate, identical monthly payment, and Lender B still costs you roughly $2,850 more at closing. There is no math where B is the cheaper loan. This is exactly why the same rate can quietly be one of the most expensive loans on your table, and why the cash-to-close line, not the rate, is the decision number.
Then the second step: the lowest rate versus the lowest cost. Lender A offers 7.03% with one point, $1,520, and a $1,500 origination fee. Lender B offers 7.28% with a $750 fee and a $1,000 lender credit. Lender B costs about $3,000 less at closing, at roughly $25 more a month, a break-even near twelve years. If you plan to be in the house longer than that, Lender A wins over the life of the loan; if you expect to move or refinance in five to eight years, Lender B very likely costs you less in total. The cheapest loan is the one that costs you the least for the time you will actually hold it, which is why the answer genuinely depends on your plan.
Page three, the Comparisons box: the five-year cost nobody quotes
Page three of the Loan Estimate carries a Comparisons box with the total interest paid over five years, the total of all payments over five years, and the APR. The five-year number is the closest thing to an apples-to-apples price tag, because it captures both the monthly cost and the upfront cost over a horizon most buyers actually live. One lender can structure the same rate with more upfront fees, and the five-year cost says so plainly. It is the single best shortcut for comparing two estimates that quote the same rate.
The questions buyers are actually asking, answered with current numbers
Is the Peoria market slowing down? Yes in pace, no in price. Cumulative days on market stretched to 25 over the past year and September closings rose 6.7%, but the county median is $175,000, down 1.4%, and inventory sits at 1.5 months of supply. Slower does not mean cheaper, which makes the lender comparison matter more, not less, because financing terms are where the savings are found.
Do Peoria buyers have more negotiating power right now? More than last year, yes, especially on homes priced above their evidence. Seller-paid closing costs and rate buydowns show up in negotiation now, and a buydown is a lender credit in disguise, so the loan comparison is exactly what tells you what a buyer contribution is worth at your table.
Is renting still cheaper than buying? In Peoria, no, buying remains the cheaper monthly move, roughly $990 a month versus about $1,133 in rent on the Construction Coverage study reported by the Peoria Journal Star. The affordability gap comes right back to lender terms, so an extra $25 a month from one loan versus another is not noise, it is the whole difference some months.
Should Peoria buyers wait for mortgage rates to drop? Nobody can reliably predict rates, and the other side of the ledger is knowable: values held roughly flat year over year, and on a median-priced home a half-point drop is roughly offset by a $10,000 to $15,000 rise in price. What you can control today is the structure of your own loan, so shop it like a professional before you wonder about the market's timing.
The short checklist before you pick
-
Get at least three Loan Estimates, and request them close together so rates do not move between quotes.
-
Compare the same loan amount, same program, same property, and same down payment, or the comparison is meaningless.
-
Add up Section A at every lender before you look at anything else, then compare cash-to-close and the five-year cost.
-
Ask for the points and credits in dollars, and for the break-even on each, against the time you plan to hold the loan.
-
Never compare before you lock a rate in writing, because a verbal quote without a lock is a moving target.
