The four paths in plain English
Sell first
Close on your Carlsbad sale before you buy, so the proceeds are in the bank when you write an offer. A rent-back holds you over for a few weeks; after that, a rental.
When owners often choose it: Sellers who want a certain budget for the next purchase, or whose down payment comes from this sale.
Tradeoffs: Time between homes, rent at Carlsbad levels, and possibly a second move.
Same-day closings
Once your buyer has removed contingencies, you offer on the next home with no sale condition and schedule both closings for one day.
When owners often choose it: Owners who want to move once and avoid renting, with a buyer who can close later.
Tradeoffs: Your buyer’s escrow is longer than usual, and a delay on one side holds up both.
Contingent offer
Your purchase depends on your Carlsbad home selling, written on C.A.R.’s COP addendum, and the two close on the same day.
When owners often choose it: Owners who find the next home before listing, and a seller willing to wait.
Tradeoffs: Contingent offers can lose out when bidding is competitive. The addendum sets the time you have to sell and whether the seller keeps marketing.
Buy first with equity
An equity line opened before listing, or a bridge loan, provides the down payment; you buy and move, then sell, and the sale pays back the loan.
When owners often choose it: Owners with significant equity who want one move and an empty home to show.
Tradeoffs: Two sets of payments at Carlsbad prices, interest and fees on a large equity loan, and qualifying with both.
Rent-backs: put it in writing
A rent-back is negotiated as part of the sale. Under C.A.R.’s forms, a stay of 29 days or fewer is usually an SIP addendum, and 30 days or more is a Residential Lease After Sale that creates a landlord-tenant relationship (San Diego Association of REALTORS®). The buyer must agree, so raise it before you accept an offer.
Contingent offers
To make your purchase depend on your sale, agents use C.A.R.’s COP addendum (revised June 2024). It records your deadline to sell, whether the other seller may continue showings and what follows if they receive another offer. Rudy prepares it with you.
Questions to ask your lender
- Will you qualify me with both payments? Fannie Mae’s guide counts both unless my current home has a signed buyer and its financing contingencies are cleared.
- Is the next loan a jumbo loan, and how is it priced compared with a conforming one?
- How large a credit line could my Carlsbad equity support if I open it before listing?
- How long can I lock my rate, and what does an extension cost?
Owners 55 and older: Proposition 19 timing
Under Proposition 19, Carlsbad owners who are 55 or older or severely disabled, and victims of a wildfire or natural disaster, may keep their tax base when they buy or build a replacement within 2 years of the sale, before or after. Its value is tested against the original’s: 100% if bought first, 105% within a year after the sale, 110% within two.
Buy before you sell and the Board of Equalization dates the transfer to whichever transaction comes second, with full-value tax in between and no refund. The county assessor makes the call; a tax adviser can look over your timing.
On loans: in 2026 the one-unit conforming limit in San Diego County is $1,104,000 (FHFA). A bigger loan is a jumbo loan with its own pricing and rules, so the rate in this tool, a conforming average, is only a starting point.
For Carlsbad figures on the tax side, open the downsizing calculator. The rules: Prop 19 when you move within California.
About these numbers
- Calendar days; weekend closings are flagged, never moved.
- After both closings the equity is identical on every path; the cash tied up before then and the costs each path adds are the real differences.
- Rent and carrying costs are prorated by the day.
- Capital gains tax isn’t included, which matters at Carlsbad prices, so ask your CPA. Lenders set rates and approval.
Questions owners ask
Do I need a jumbo loan for my next Carlsbad home?
If the loan is above $1,104,000 in 2026, yes. Jumbo loans are priced and approved separately, so get a quote early.
Can I buy first if most of my wealth is in this house?
Possibly, with a home equity line opened before listing or a bridge loan. The buy-first column shows how much the equity loan covers and what it costs.
Will Carlsbad sellers accept a contingent offer?
Some do, especially when a home has been on the market a while. A strong offer and a clear plan to list help.
How long could I stay after selling?
An SIP addendum usually covers a stay of 29 days or fewer; anything longer calls for a lease after sale, and your buyer has to agree.
