Refinancing your mortgage is a significant financial decision. When done right, it can save you tens of thousands of dollars. When done poorly, it can cost you more than staying put. Here are seven mistakes we see DC homeowners make — and how to avoid them.
1. Focusing Only on the Interest Rate
A lower rate is great, but it's not the whole picture. Closing costs, loan terms, and how long you plan to stay all factor into whether a refinance actually saves you money.
The fix: Always calculate your break-even point. Divide total closing costs by your monthly savings. If you'll move before you break even, the refinance costs you money regardless of the rate.
A $200/month savings sounds great — but if closing costs are $15,000 (not unusual in DC), you need 75 months to break even. That's over 6 years.
2. Ignoring State and Local Closing Costs
This is uniquely important in DC, where recordation tax rules are widely misunderstood — including by homeowners who overestimate what they'll owe.
The fix: Get a detailed Loan Estimate that includes all government recording charges. DC fully exempts residential refinances from recordation tax — including the entire loan on a cash-out — for homes with 5 or fewer units, claimed with a one-page Security Affidavit your settlement agent records at closing (D.C. Code § 42-1102(21)). If your estimate shows recordation tax on a residential refinance, ask why.
3. Not Shopping Multiple Lenders
Rate and fee quotes vary more than most people realize. The difference between the best and worst offer can be 0.25–0.50% in rate or several thousand dollars in fees.
The fix: Get quotes from at least 3 lenders. Apply within a 14-day window so all credit inquiries count as a single pull. Compare the APR (which includes fees) rather than just the rate.
According to research, borrowers who get five quotes save an average of $3,000 over the life of the loan compared to those who only get one.
4. Resetting to a 30-Year Term Without Thinking
When you refinance, you're offered a new 30-year term by default. If you're 8 years into your current mortgage, refinancing to a new 30-year loan adds 8 years to your payoff timeline.
The fix: Consider matching your remaining term. If you have 22 years left, look at a 20-year refinance. Your payment will be slightly higher, but you'll pay dramatically less interest over the life of the loan.
Example on a $400,000 balance at 6.25%:
- 30-year: $2,462/month, total interest $486,320
- 20-year: $2,918/month, total interest $300,320
That's a $186,000 difference in total interest paid for $456 more per month.
5. Forgetting About Mortgage Insurance
If you originally put less than 20% down, you might be paying PMI (conventional) or MIP (FHA). Refinancing is an opportunity to eliminate it — but only if you structure the deal correctly.
The fix:
- Get an appraisal to confirm your current home value
- If you have 20%+ equity, ensure the new conventional loan is structured without PMI
- If you have an FHA loan, refinancing to conventional is the only way to drop the lifetime MIP
In DC's appreciated market, many homeowners who bought with 5–10% down now have 20%+ equity. Don't leave that savings on the table.
6. Rolling All Costs Into the Loan Without Considering the Impact
"No out-of-pocket closing costs" sounds appealing, but rolling $15,000 in costs into your loan means you're borrowing more and paying interest on those costs for decades.
The fix: Run the numbers both ways:
- Option A: Pay $12,000 in closing costs upfront, loan balance stays at $400,000
- Option B: Roll costs in, loan balance becomes $412,000
At 6.25% over 30 years, that extra $12,000 costs you about $26,500 in total (principal + interest). If you have the cash, paying upfront is usually the better deal.
That said, if you'd otherwise deplete your emergency fund, rolling in costs is the prudent choice. Financial flexibility has value too.
7. Timing the Market Instead of Running the Numbers
"I'll wait for rates to drop more" is the most common reason homeowners miss good refinance opportunities. Nobody can reliably predict rate movements.
The fix: Base your decision on math, not forecasts:
- Does the refinance save you money at today's rates?
- Will you stay long enough to break even?
- Does the new loan improve your overall financial position?
If the answer to all three is yes, the refinance makes sense — regardless of what rates might do next month.
A Simple Pre-Refinance Checklist
Before you start the process, gather these:
- Current mortgage statement (rate, balance, payment, remaining term)
- Recent property tax bill
- Homeowners insurance declaration page
- Two most recent pay stubs
- Two most recent bank statements
- Most recent W-2s or tax returns
- Your credit score (check for free at annualcreditreport.com)
Having these ready speeds up the process and helps you compare offers accurately. The best refinance is the one where you've done the homework upfront and can make a confident, informed decision.
