property nerd guide · sellers
Moving up in Silicon Valley usually means lining up two big transactions at once. Here's a plain comparison of the common ways to sequence them, from rent-backs to bridge financing, and how to choose the one that fits your family and your finances.

the short version
Every plan is a version of two choices
Selling first gives you certainty about your proceeds and your buying power. Buying first gives you an easier move. Most plans are a mix of the two.
If you sell first, you know exactly what you have to spend, and you never carry two homes. The trade-off is that you may need somewhere to live while you shop. If you buy first, you move once and can take your time preparing the old house. The trade-off is that you need the money or financing to own both homes for a while.
When much of your net worth is in your house, how you unlock that equity often decides the plan. That's why we start with your numbers, not with a listing date.
before you choose
Five questions to answer first
- How much equity do you have, and how much could you get to before you sell?
- Could you qualify to carry both homes for a few months? Your lender can answer this one.
- How long could you stay put after a sale, and is a short interim move workable for you?
- How competitive is the market you're buying into? That decides whether a contingent offer can work.
- Are you 55 or older and planning to use Prop 19? Your timing changes your value limit.
the options
The options side by side
Here's how the common approaches compare. Financing details depend on your lender, your credit and your assets, so treat this as a map for that conversation.
| Option | How it works | Best when | Watch out for |
|---|---|---|---|
| Sell first + rent-back | You sell and close, then stay in the home for an agreed period while you buy. | You want proceeds in hand and a firm budget before you shop. | The buyer has to agree, and the length and terms are negotiated. A long search may still need short-term housing. |
| Buy first with a bridge loan or HELOC | You borrow against your current home's equity for the down payment on the next one. | You've found the right home and can qualify to carry both for a while. | Approval, fees and two sets of payments. Set this up with your lender early, before you're under pressure. |
| Buy first with cash or other assets | You use savings or other assets to buy, then sell the old home. | You have enough liquid assets to buy without waiting. | Selling investments can trigger taxes. Talk with your CPA and financial advisor first. |
| Contingent offer | Your purchase depends on your current home selling. | The seller has fewer offers or values your terms. | In a multiple-offer situation, a contingent offer usually competes poorly against non-contingent ones. |
| Simultaneous close | Both escrows are timed to close on the same day or back to back. | Both sides are flexible and the timing lines up. | A delay on one side affects the other, and moving day gets tight. |
| Prep with Compass Concierge | Compass Concierge fronts the cost of eligible prep work, with nothing due until closing. | The house needs paint, staging or repairs and you'd rather not pay up front. | Terms and eligibility vary, and fees or interest may apply depending on the state. |
| Test the price first | A Compass Private Exclusive shares your home with Compass agents and their buyers before it goes public. | You want feedback on price before deciding to buy or sell first. | Limited exposure means fewer buyers see it, so we weigh that trade-off together. |
Selling first feels like
A clear budget, no double payments, and a stronger position when you write offers. It can also mean two moves, or a rent-back that puts a date on your search.
Buying first feels like
One move, time to prepare the old house, and no rush to find the next one. It also means carrying costs and some risk if your sale takes longer than planned.
getting ready
Prep without paying up front
Whichever order you choose, the old house usually needs attention before it sells. Compass Concierge can front the cost of eligible prep work, such as staging, painting, flooring and repairs, with nothing due until closing. Terms and eligibility vary, and fees or interest may apply depending on the state, so we'll go through the details with you before any work starts.
That matters most for buy-first sellers, who want the old house ready quickly, and for sell-first sellers, who want the strongest possible price before they shop.
property nerd note
If you're 55 or older and plan to use Prop 19, the order matters for your property tax. Buy before you sell and you can keep your full tax base on a home worth up to 100% of your old home's sale value. Buy in the first year after selling and that rises to 105%; in the second year, 110%. We build that into the plan.
property nerd note
Rent-backs are written into the purchase contract. We negotiate the length, the cost and the deposit up front, and we check whether the buyer's lender has occupancy rules that limit how long you can stay.

faq
Sell first or buy first: FAQ
How long can a rent-back last?
It's negotiated with the buyer and written into the contract. The buyer's lender may have its own occupancy rules, so we confirm the limits before we agree to a date.
Is a contingent offer ever a good idea here?
Sometimes. It can work when a seller has few offers or values your price and terms. When several buyers are competing, a non-contingent offer is usually stronger.
What's the difference between a bridge loan and a HELOC?
Both let you borrow against your current home's equity. A bridge loan is short-term financing meant to cover the gap between buying and selling. A HELOC is a line of credit you draw on as needed. Your lender can explain the costs and requirements of each.
Does Compass Concierge cost anything up front?
Compass describes it as zero due until close for eligible services. Terms and eligibility vary, and fees or interest may apply depending on the state, so we'll walk through them before you decide.
