When Refinancing Makes Sense
The classic rule of thumb. A 0.5 to 0.75 percentage point drop in your rate is the threshold where the closing costs start to pencil out. Anything less and you are likely paying $2,000 to $3,500 in closing costs to save $50 or $80 a month, which takes years to recoup.
Real Houston example. You took out a $400,000 loan at 7.25% in 2024. Rates drop and you can lock 6.50% today. Your principal and interest payment falls from about $2,728 to $2,528, a $200 monthly savings. With $3,000 in lender costs, your break-even is month 15. If you keep the home (and the loan) past month 15, every dollar after that is yours to keep.
Stretch the math out. Same loan, same rate drop, kept for the full remaining 28 years. Total interest savings exceed $65,000. The $3,000 in closing costs is a rounding error against that.
The pivot point is how long you plan to stay. If you are selling in 18 months, a refi that breaks even at month 24 destroys value. If you are settling in for the next decade, almost any rate drop over 0.5% justifies the cost.

Rate-and-Term Refi
The simpler of the two main paths. You replace your current mortgage with a new one at a better rate, a different term, or both. No cash leaves the deal in your direction. The goal is to lower the monthly payment, lower the total interest paid, or shorten the payoff timeline.
Typical Houston rate-and-term cost structure:
- Origination fee: $0 to $1,500
- Appraisal: $550 to $750
- Title insurance (reissue rate in Texas): $400 to $1,200 depending on loan amount
- Recording, courier, credit report, escrow setup: $300 to $500
- Prepaid interest, escrow funding: varies by closing date
Total lender costs run roughly $1,500 to $3,500 on a Houston rate-and-term refi. No cash to the borrower. The new loan amount equals the existing payoff plus rolled-in closing costs (if you choose that route).
Rate-and-term is also the move if you want to drop FHA mortgage insurance. Refinancing an FHA loan into a conventional loan once you cross 20% equity eliminates MIP entirely, which on a $300,000 FHA loan saves about $130 per month for the life of the loan.
Cash-Out Refi
You replace your existing mortgage with a larger one and take the difference in cash at closing. Useful for funding home improvements, consolidating high-interest debt, buying an investment property, or capitalizing a business.
Conventional cash-out tops out at 80% LTV on a primary residence. FHA cash-out also tops out at 80% LTV. VA cash-out can go to 100% LTV on a qualifying veteran's primary residence, the most generous of the three.
Texas adds rules that other states do not have. The 50(a)(6) provision treats cash-out as a separate product with an 80% LTV cap, a 12-month seasoning window between cash-outs, and a $7,500 cap on total fees. Once a home has been the subject of a cash-out refi in Texas, the homeowner can pursue future cash-out refis but cannot return to a "regular" rate-and-term until the 50(a)(6) lien is fully retired.

Streamline Refis (FHA IRRRL, VA IRRRL)
If your existing loan is FHA or VA, you have a faster track. Streamline refinances (FHA's Streamline Refinance and the VA's Interest Rate Reduction Refinance Loan) skip most of the documentation and appraisal steps that slow a conventional refi.
| Feature | FHA IRRRL | VA IRRRL |
|---|---|---|
| Income documentation | Not required | Not required |
| New appraisal | Not required | Not required |
| Credit check | Often waived | Often waived |
| Net tangible benefit required | Yes (0.5% rate drop or equivalent) | Yes |
| Cash out allowed | No | No |
| Typical closing time | 21 to 30 days | 21 to 30 days |
| Funding fee / UFMIP | 1.75% UFMIP (refundable portion of original) | 0.50% funding fee |
Streamlines work best when rates have dropped meaningfully from when you closed your original FHA or VA loan. The "net tangible benefit" rule prevents homeowners from refinancing into a worse product, so the new loan must lower the rate, lower the payment, or shorten the term in a measurable way.
Houston-Specific Considerations
A few Texas and Houston specifics that affect refinances:
Homestead exemption stays put. Your Texas homestead exemption is attached to the property, not the loan. A refinance does not reset it, does not require reapplication, and does not interrupt your school district appraisal cap. The 10% annual cap continues uninterrupted.
Property tax escrow re-evaluated. Most lenders escrow taxes and insurance. At refinance, the escrow account is re-evaluated against the most recent Harris County (or Fort Bend, Montgomery, etc.) tax bill. If your taxes went up since the last escrow analysis, your monthly payment may rise to fund the increase, even with a rate drop.
MUD adjustments do not apply at refinance. If you bought in a Municipal Utility District (MUD), your tax rate may step down over time as the MUD pays off its bonds. A refinance does not change the rate. The MUD assessment is a separate process tied to the district, not the mortgage.
Flood zone status. If FEMA has remapped your area since your original loan closed, your refinance may trigger a new flood determination. If you moved into a higher-risk zone, the new lender may require flood insurance. We check this before locking your rate.
The Bundle does not apply to refinances. The InSync Bundle ($7,500 back at closing) is reserved for buyers who pair their real estate purchase with their mortgage through InSync. A refinance is mortgage only, so there is no real estate commission to rebate. We still offer competitive lender credits where the math works, just not the Bundle.
