Bridge Loans: How They Work and When to Use Them

What Bridge Loans Are and Why They’re Used

A bridge loan provides short-term financing to “bridge” the gap between two financial events. In residential real estate, the prototypical use case is purchasing a new primary residence before the sale of an existing one proceeds. In commercial real estate, bridge loans fund property acquisitions during transitional periods — lease-up, renovation, or occupancy stabilization — when the property doesn’t yet qualify for permanent financing.

The residential bridge problem clearly stated: you own a home worth $680,000 with a $380,000 remaining mortgage (equity: $300,000). You’ve found and negotiated a new home at $850,000 but need a $170,000 down payment. Your equity is there — but it’s locked in the existing home until you sell. A sale contingency offer on the new home might work, but in a competitive market the seller has better offers. You need to close on the new home now. The bridge loan leverages your existing equity to fund the new purchase. You close both transactions, move in, then sell the old home at an appropriate price without the contingency’s time pressure.

Bridge Loan Mechanics and Cost Structure

Residential bridge loans typically lend at 70–80% of your existing home’s appraised value minus the outstanding mortgage balance. At 75% LTV: $680,000 × 75% = $510,000 maximum total debt. Minus $380,000 existing mortgage: $130,000 available as bridge. This $130,000 funds 15.3% down on the $850,000 new home — reducing the new mortgage to $720,000 and keeping the total debt at manageable levels during the bridge period.

Cost structure: interest rate at approximately Prime + 1.5–3.0% = 9.0–10.5% in 2025 market conditions. Origination: 1–2 points. Structure: interest-only during the bridge term. Term: typically 6–12 months. Total cost for a 5-month $130,000 bridge at 10% rate and 1 point: $1,300 origination + $5,417 interest = $6,717 total. Compare to the alternative of accepting a discounted contingency offer that costs $30,000 in price concession — bridge financing frequently produces better financial outcomes when the numbers are honestly compared.

During the bridge period, you’ll carry three simultaneous debt obligations: the existing home’s $380,000 mortgage, the $130,000 bridge, and the new $720,000 purchase mortgage. Monthly obligations: approximately $2,500 (existing) + $1,083 (bridge interest-only) + $4,800 (new PITI) = $8,383/month combined. This is the reality of bridge periods — they’re designed to be short for exactly this reason. Most bridge transactions complete in 3–6 months when the prior home is properly staged and priced.

Texas Constitutional Framework for Bridge Loans on Homesteads

Texas’s unique constitutional home equity framework (Article XVI, Section 50) creates specific constraints that borrowers in other states don’t face. The 80% combined LTV limit, mandatory 12-day waiting period between application and closing, the one-per-year restriction on Texas home equity transactions, and specific-purpose restrictions all apply to home equity-based bridge products on Texas primary residences.

For Texas bridge transactions, lenders familiar with the constitutional framework often structure the bridge as a non-purchase-money first lien against the departing property rather than a home equity product — avoiding some of the constitutional restrictions while achieving the same economic result. Alternatively, using a bridge against investment property or a second home (not a Texas homestead) avoids constitutional restrictions entirely. Work with a lender who explicitly understands Texas home equity law, not a national bridge lender whose standard product may not comply with Texas’s requirements or may encounter delays from the mandatory waiting periods that can disrupt your target closing timeline.

Commercial Bridge Loan Use Cases

In commercial real estate, bridge loans serve three primary functions:

Value-add bridge financing: The most common commercial use. A multifamily or commercial property has deferred maintenance or below-market occupancy — perhaps 60% occupied at rents 20% below market. The current income doesn’t support DSCR requirements for agency or conventional permanent financing (Fannie Mae DUS, Freddie Mac, CMBS). The bridge loan funds acquisition and renovation; the exit is a permanent loan refinance once renovation is complete and occupancy stabilizes at 85–90% with market rents. Bridge terms: 12–36 months, 65–75% of stabilized value, SOFR + 3–5% rate, 1–2 origination points.

Lease-up bridge: Newly constructed commercial property with certificate of occupancy but insufficient occupancy to generate cash flow meeting permanent financing DSCR requirements. The bridge carries the property through 12–24 months of lease-up until the income stream matures.

Distressed acquisition or time-sensitive close: A commercial property in foreclosure, receivership, or a sale requiring sub-30-day close that conventional commercial financing (60–90 days) can’t accommodate. The bridge provides speed and certainty at a rate premium.

Alternatives to Bridge Financing Worth Evaluating

Bridge loans are the right answer for some situations and an expensive answer for others. Before committing to bridge financing costs and complexity, evaluate these alternatives:

Sale contingency with kick-out clause: Your offer on the new home is contingent on your existing home selling. The seller can accept with a kick-out clause — they retain the right to continue marketing; if they receive another non-contingent offer, you have 72 hours to remove the contingency or terminate. Works well in balanced markets where non-contingent offers aren’t flooding every listing. Less effective in competitive seller’s markets where non-contingent offers are abundant and sellers routinely reject contingencies.

Buy-before-you-sell fintech programs (Homeward, Knock): These companies provide mechanisms to purchase before selling, charging 1.5–3% of purchase price. Compare their fee to your bridge loan’s total cost — points plus interest over the expected bridge hold period. On a $750,000 purchase, a 2% program fee = $15,000 versus a typical bridge loan total cost of $7,000–$10,000 on $120,000 over 5 months. Bridge financing is often cheaper but more complex to execute. These programs offer simplicity at a cost premium.

Extended close negotiation: A 75–90 day close provides time to sell your existing home before the new purchase closes, eliminating the bridge entirely. Sellers in non-rush relocation situations sometimes accept extended timelines in exchange for favorable pricing or other terms. Most effective in buyer’s markets or with sellers who have flexibility about their own move-out timing.

Herring Bank’s commercial lending team works with real estate investors and residential buyers on bridge financing needs. Our team can evaluate both the constitutional framework for Texas transactions and the deal economics to determine whether a bank portfolio bridge product is achievable and cost-competitive for your specific situation and timeline.

When Bridge Financing Doesn’t Make Financial Sense

Identify the scenarios where bridge cost exceeds benefit before committing: if your existing home sale timeline is uncertain (overpriced relative to market, condition issues, difficult showing situation), bridge carrying costs escalate with each additional month — a 4-month bridge that runs 8 months doubles the interest cost and adds extension fees. If a contingency offer at modest price concession would cost less than the bridge, accept the concession. If the bridge’s total cost approaches or exceeds what you’d lose on a contingency offer discount, the convenience isn’t worth the cost. Bridge loans reward realistic exit timelines; they punish optimistic ones.
