The difference between a 6.5% and 7.25% mortgage rate on a $400K loan is $192/month, $2,304/year, and $69,120 over 30 years. Shopping multiple lenders is one of the highest-return activities a Tampa Bay homebuyer can do before closing. The CFPB reports that borrowers who compare at least three lenders save an average of $1,500 in origination costs alone, and often far more on the rate itself. Here is exactly how to do it.
How Many Lenders Should You Compare?
At minimum, get quotes from three lenders: one large bank (Chase, Wells Fargo, Bank of America), one mortgage broker, and one local lender or credit union (GTE Financial, MidFlorida Credit Union, Achieva Credit Union). Rate quotes are only comparable if they are from the same day because rates change daily, sometimes twice daily. A Tuesday quote from one lender cannot be meaningfully compared to a Thursday quote from another. Request Loan Estimate documents from each lender on the same day and compare the APR (which includes fees), not just the interest rate.
What Factors Affect Your Mortgage Rate in Tampa Bay?
Credit Score
Your credit score is the single biggest factor you can control before applying. Here is how score ranges typically affect rates on a conventional loan:
| Credit Score | Rate Adjustment (vs. 760+) | Monthly Impact ($400K Loan) |
|---|---|---|
| 760+ | Best available rate | Baseline |
| 740-759 | +0.125-0.25% | +$30-$60/month |
| 720-739 | +0.25-0.50% | +$60-$120/month |
| 700-719 | +0.50-0.75% | +$120-$180/month |
| 680-699 | +0.75-1.00% | +$180-$240/month |
| Below 680 | +1.0%+ or FHA/VA only | +$240+/month |
Down Payment
On conventional loans, a 20%+ down payment gets the best rates and eliminates PMI. The difference between 5% and 20% down is typically 0.125-0.375% in rate. More importantly, less than 20% down adds private mortgage insurance (PMI) of 0.4-0.8% annually until you reach 20% equity. On a $400K loan with 5% down, PMI adds $130-$265/month on top of your base payment.
Loan Type
Not all loans price the same. For buyers with strong credit (720+), conventional loans typically offer the best pricing. FHA loans include a mortgage insurance premium (MIP) for the life of the loan on 30-year mortgages with less than 10% down. VA loans typically offer rates 0.25-0.50% below conventional and have no PMI, making them the best option for qualifying veterans.
Loan Term
A 15-year mortgage rate is typically 0.5-0.75% lower than a 30-year. The monthly payment is significantly higher (because you pay off the loan in half the time), but the total interest paid over the life of the loan is dramatically less. For buyers who can comfortably afford the higher payment, the 15-year is powerful for wealth building.
Property Type
Condos in Florida carry a pricing premium of 0.125-0.375% above single-family loans because lenders view condo collateral as higher risk (HOA health, building issues). Investment properties carry 0.5-0.75% higher rates than primary residences. Vacation/second homes are priced between the two.
Should You Buy Discount Points to Lower Your Rate?
Buying "points" means paying an upfront fee to permanently lower your interest rate. One point = 1% of the loan amount. On a $380K loan, one point costs $3,800 and typically lowers your rate by 0.25%.
Break-Even Calculation
On a $380K loan at 7.0%, one point lowers the rate to 6.75%. Monthly payment drops by $65. Break-even: $3,800 / $65 = 58 months (about 4.8 years). If you stay in the home or keep the loan more than 5 years, buying the point saves money. If you might sell or refinance within 3-4 years, skip the points.
When Points Make Sense
- You plan to stay in the home 7+ years
- You are in a period of high rates and do not expect to refinance soon
- The builder or seller is offering to buy down the rate (this is free money; always take it)
When to Skip Points
- You might sell within 5 years
- You expect rates to drop significantly and plan to refinance
- You need the cash for closing costs, down payment, or reserves
What About Builder Preferred Lenders?
Builders like Lennar, D.R. Horton, and Taylor Morrison offer closing cost credits and rate buydowns to buyers who use their affiliated mortgage companies. The incentive package is often worth $10,000-$30,000 in concessions. But the preferred lender's rate and fees may not be the most competitive.
How to Evaluate Builder Lender Offers
- Get a full Loan Estimate from the builder's preferred lender (rate, all fees, APR)
- On the same day, get a Loan Estimate from an outside lender for an identical loan amount and program
- Calculate the total cost of each option over 5 years (not 30, since most people do not keep a mortgage 30 years): (monthly payment difference x 60) + (closing cost difference)
- Compare which option has lower total 5-year cost including the value of any incentives
Sometimes the builder incentive wins even with a higher rate. Sometimes outside financing is cheaper even without the incentive. The only way to know is to run the math. Barrett helps buyers make this calculation, call (813) 733-7907 or contact Barrett.
When Should You Lock Your Rate?
Rate locks are available for 30, 45, or 60 days (sometimes longer, for a fee). Once locked, your rate does not change regardless of market movement. Lock too early (before you have a signed contract) and you may pay for the lock without using it. Lock too late and rates may rise before closing.
General Rate Lock Strategy
- For a resale purchase: lock after you have a signed contract and are certain the deal will close
- For new construction with a 6-month build time: many builders' lenders offer extended locks (6-12 months) for a fee; compare the lock fee to the cost of a potentially higher rate at closing
- In a falling rate environment: a float-down option lets you benefit if rates drop after you lock (ask your lender if they offer this)
What to Watch Out for When Comparing Lender Quotes
APR vs. Interest Rate
The advertised interest rate does not include fees. The APR includes origination fees, discount points, and most other costs. Always compare APR when evaluating lenders, not just the interest rate. A 6.75% rate with $4,000 in fees may cost more than a 6.875% rate with $500 in fees, depending on how long you keep the loan.
Origination Fees
Also called lender fees or underwriting fees. These are in addition to discount points. Legitimate origination fees typically run $800-$2,500. Fees above $3,000 on a conventional loan deserve scrutiny. Compare the Loan Estimate's Section A (origination charges) across lenders.
Rate Float-Down Options
Some lenders offer a one-time float-down if rates drop by a specified amount after you lock. There may be a fee for this option. In a volatile rate environment, this is worth asking about at every lender you compare.

What is the current mortgage rate in Tampa Bay?
Mortgage rates change daily and are not location-specific; Tampa Bay buyers see the same national rate environment as everyone else. The rate you receive depends on your credit score, down payment, loan type, and the lender you choose. For the most accurate rate, get pre-approved by at least two lenders and compare their Loan Estimates on the same day.
How much does a 1% higher mortgage rate cost?
On a $380K loan, a 1% higher rate adds approximately $239/month to your payment. Over 5 years, that is $14,340. Over the full 30-year term, it is $86,040. This illustrates why improving your credit score before applying, even by 40-60 points, can have a significant financial impact.
Should I use a mortgage broker or bank in Tampa Bay?
Both have advantages. A mortgage broker shops your loan to multiple wholesale lenders simultaneously, which can surface rates and programs not available directly from a single bank. A bank lender you already have a relationship with may offer a discount. Include both in your comparison of at least three quotes. Local credit unions like GTE Financial and MidFlorida often offer competitive rates with lower fees than national banks.
Can I use a builder's preferred lender in Tampa Bay?
Yes, and in many cases the builder incentive makes the preferred lender the right financial choice. But you need to run the numbers. Get a Loan Estimate from the builder's lender and from at least one outside lender on the same day, then calculate total 5-year cost including the value of any incentive credits. Do not assume the builder lender is better or worse without the comparison.
When should I lock in my mortgage rate?
Lock your rate after you have a signed purchase contract and are confident the deal will close. For resale purchases, a 30-45 day lock is typically sufficient. For new construction, ask the builder's lender about extended lock programs (6-12 months). In uncertain rate environments, a float-down option (if offered) gives you downside protection at a small premium.
