Choose the order before choosing closing dates
Selling first lets you know your actual sale proceeds before committing them to a purchase, but you may need temporary housing, storage, and possibly two moves. Buying first lets you move directly into the next home and prepare the old one afterward, but you must qualify for the purchase and pay both homes' expenses until the old one closes. Coordinating both closings can put sale proceeds toward the next purchase with less time between moves, but one transaction then depends on the other and you still need a backup place to stay.
None of these is automatically the right choice, and this comparison is not a recommendation to take on additional debt. Ask your agent to compare likely selling conditions for your specific home with the inventory you would realistically buy. A broad market average cannot tell you how quickly either transaction could close.
Separate equity, available cash, and buying power
An estimated home value is not your next down payment. Start with a seller net sheet: expected sale price, less mortgage and other lien payoffs, selling costs, and agreed credits or other charges. Keep moving costs and a reserve separate from the money you intend to put into the next purchase, and ask for a revised estimate whenever contract terms change.
Lenders also need documentation. Under Fannie Mae's Selling Guide, when sale proceeds are needed for the next down payment or closing costs, the lender must obtain the existing home's settlement statement, before or at the same time as the new settlement, showing sufficient net cash proceeds; a sales contract or listing agreement alone is not enough. Other loan programs and lenders may differ, so your lender and closing attorney should confirm the sequence for your transaction.
Do not assume that putting your home under contract removes its payment from qualification. Fannie Mae generally counts both housing payments when the current home has not yet transferred, with an exception that requires the executed sales contract and confirmation that any financing contingencies have been cleared. Ask your lender what your approval requires both with and without the old home sold, and whether your program follows the same rules.
If you have lived in the home for a long time, ask a tax professional whether any part of your gain may qualify for the IRS home-sale exclusion, which has ownership-and-use tests and limits, so you can plan around the tax consequences rather than discover them afterward.
If you buy first, understand the financing before making an offer
Ask the lender to compare the total cost and conditions of any proposed solution, not just whether it produces a down payment.
A bridge loan may help cover a gap between transactions, but it adds another obligation. Fannie Mae's guidance requires the lender to document that the borrower can carry the payments on the new home, the current home, the bridge loan, and other obligations. Availability, terms, and eligibility depend on the lender and loan program, so ask about fees, repayment dates, and what happens if the sale takes longer than expected.
A home-equity loan or HELOC uses your home as collateral. These are loans, not free access to future sale proceeds: interest and fees apply, HELOC rates are typically variable, and if you do not repay, the lender can take the home. Ask whether the product is available for your circumstances, how it affects the new mortgage, and what must be paid off when you sell.
Price the uncomfortable version of the plan, too: the old house still unsold, both sets of ownership expenses due, and an unexpected repair. If that scenario does not fit your budget, revisit the order of the move before committing.
Put the dependency into the contract conversation
If you cannot buy without selling, tell your agent and attorney before submitting an offer. South Carolina REALTORS publishes a form addendum for a buyer's property-sale contingency, and a contingency's protection depends on the agreed language, deadlines, and required notices. Telling the seller you need to sell is not a substitute for agreed contract terms. Ask your attorney which current form and terms fit the transaction; the seller is not required to accept a contingent offer.
Have the team explain three separate questions: must your existing home be under contract, must it actually close, and by when? Also ask what happens if the seller receives another offer. Do not waive a sale dependency on the assumption that financing will somehow work out.
Put earnest-money delivery, inspections, appraisal, financing, sale-contingency dates, closing, and possession on one calendar. Ask your attorney how each deadline affects your rights and your deposit, and do not assume that a delay automatically extends either agreement or entitles you to a refund.
Coordinate the closing and the move separately
In South Carolina, residential real-estate closings are conducted under the supervision of an attorney. Involve the closing attorney early, particularly if the home you are selling is in another state or its proceeds fund the South Carolina purchase. Ask both closing offices how proceeds will be transferred, what documents they need, when funds can be used, and when you can receive keys.
Two appointments on the same day are a schedule, not proof that the second transaction is funded. Have your lender and attorneys approve the proposed order before you make nonrefundable moving arrangements.
For mortgages covered by the federal Closing Disclosure requirement, the lender must provide it at least three business days before closing. Compare it with your Loan Estimate, check the cash needed, and ask about anything that changed. This is one checkpoint, not confirmation that everything else is ready.
If staying in the old home briefly after selling would help, ask about a written post-closing occupancy agreement before agreeing to the sale. Have the attorney, lender, and insurer review possession, cost, responsibility for damage, and move-out obligations. Do not plan on remaining simply because the next home is not ready.
Build a backup plan before you need it
Choose a temporary-housing option you could actually use, including pets, accessibility needs, commute, and storage. Get moving quotes that explain rescheduling costs, keep essential documents and medicines out of storage, and confirm utility and insurance dates against possession rather than an optimistic moving target.
If one deal changes, notify your agent, lender, and closing attorney right away. Ask what remains possible under the existing agreements and what would need to be negotiated. A backup plan gives you options; it does not change a contract by itself.
A practical sequence for both transactions
This is a sequence of decisions, not a promised number of days. Before listing or offering, review estimated sale proceeds, financing scenarios, and a backup housing budget. Before signing, agree on sale dependencies, deposits, deadlines, and possession terms with professional guidance. While both contracts are active, track inspections, appraisal, loan conditions, title work, and changes on one shared calendar. Before scheduling the move, confirm funding, closing readiness, possession, and insurance. At the finish, wait for the closing offices' instructions rather than assuming that signing means funds or keys are immediately available.

Quick answers
Frequently asked
- Do I have to sell my home before buying another?
- Not necessarily. The answer depends on available cash, loan qualification, and whether you can carry both homes. Ask a lender to review both scenarios before committing to a purchase, and remember that having equity does not necessarily mean having cash available for closing.
- Can my offer depend on selling my current home?
- You can discuss a sale contingency with your agent and attorney and propose it to the seller, but it must be agreed as part of the contract. Confirm the current language, deadlines, notices, and any provisions about the seller accepting another offer; the seller may decline.
- Can I use my sale proceeds for the next down payment?
- Potentially, if there are sufficient net proceeds and you follow the documentation and funding sequence your lender requires. An estimated net sheet is not proof of available funds, so coordinate the sale settlement and transfer with both closing offices.
- Will the lender count both mortgages?
- It may. The answer depends on the loan program and the evidence of the existing home's sale. Fannie Mae's guidance has conditions for excluding the old home's payment, but a pending sale by itself does not establish that they are met. Ask your lender how your program treats it.
- Is a bridge loan or HELOC the easiest solution?
- Neither is automatically suitable. Compare qualification, fees, payments, repayment requirements, and the consequences of a delayed sale with your lender. Borrowing against your home puts it at risk if you cannot repay, so consider talking with an independent advisor before deciding.
- What if my sale is delayed or the buyer backs out?
- Tell your agent, lender, and attorney immediately so they can reassess funding and the purchase agreement's deadlines and protections. Temporary housing may address the move but does not resolve a contract or financing problem, and an extension is something to negotiate, not assume.
