Moving up is a timing problem. Your equity is tied up in the home you live in, and most sellers in a competitive Denver market do not want to wait while you sell first. The good news is that there are several proven ways to buy your next home before your current one closes. This guide compares them, explains the 2026 lender rules that decide whether you qualify with two payments, and shows how to choose the right path for your situation.
Quick answer
You can buy before you sell if you qualify with both housing payments, or if your lender can remove or offset the current one. Lenders can exclude your current payment once it is under contract with financing contingencies cleared, and they can offset it with expected rent if you plan to keep it as a rental. For the down payment, the most common sources are a HELOC opened before you list, a bridge loan against your current home, or cash reserves. If none of those fit, selling first with a rent back or making an offer contingent on your sale are the lower risk alternatives.
Can you qualify for a new home while you still own your current one?
Yes, if your income supports both payments. Under Fannie Mae’s rules, when your current home will not close before or at the same time as your purchase, the lender counts both housing payments in your debt to income ratio. The exception: once your current home is under a fully executed sales contract and the buyer’s financing contingencies are cleared, the lender can leave its payment out.
| Example household earning $22,000 a month | Counting both homes | After the current home is under contract |
|---|---|---|
| Current home payment | $2,650 | Excluded |
| New home payment ($760,000 loan at 7.03%, with taxes and insurance) | $5,772 | $5,772 |
| Other monthly debts | $600 | $600 |
| Debt to income ratio | 41.0% | 29.0% |
In this example, the buyer qualifies either way, because Fannie Mae’s automated underwriting can approve ratios up to 50% for strong files. A household with less income, or a higher new payment, may only qualify once the current home is under contract, which is why the order of steps matters.
What are your options for buying before you sell?
| Option | How it works | Watch out for |
|---|---|---|
| Sell first with a rent back | Close on your current home, then rent it back from the buyer for a short period while you buy | Limited time to find the next home and two moves if timing slips |
| Home sale contingency | Your offer depends on your current home selling by a set date | Less attractive to sellers in a competitive market |
| HELOC on your current home | Open a line of credit before you list and use it for the down payment | The payment counts in your ratios, and lenders may not open a line on a home that is already listed |
| Bridge loan | A short term loan against your current home funds the down payment until it sells | Higher cost, and the payment counts unless your home is under contract |
| Keep it as a rental | Use expected rent to offset the current payment and keep the home long term | Landlord responsibilities, reserves and a change in how the eventual sale is taxed |
| Cash reserves or investments | Fund the down payment from savings and recast or pay down the new loan after your sale | Liquidity during the gap between closings |
Should you use a HELOC or a bridge loan for the down payment?
Both tap the equity in your current home before it sells.
- HELOC: usually the lower cost option. Open it while you still live in the home and before you list it, since many lenders will not open a new line on a property that is for sale. How much you can borrow depends on the lender’s combined loan to value limit. On a $750,000 home with a $380,000 mortgage, an 80% limit would allow a line of up to $220,000. See our HELOC page for details.
- Bridge loan: designed for exactly this situation, but typically more expensive. Fannie Mae accepts a bridge loan as a source of funds as long as it is not secured by the home you are buying, and the lender must document that you can carry the new home, the current home, the bridge loan and your other debts. The bridge loan payment is counted in your ratios unless your current home is under contract with financing contingencies cleared.
After your current home sells, you can pay off the HELOC or bridge loan and, with many conventional loans, ask your servicer to recast the new mortgage so your payment reflects the lower balance.

Can you keep your current home as a rental and still qualify?
Often, yes, and Fannie Mae’s rules for this changed in 2026. Under its updated policy, which lenders can use now and must use for applications dated December 1, 2026 or later:
- You do not need a signed lease. Expected rent comes from the appraiser’s market rent analysis or at least three comparable rentals.
- The lender uses 75% of the gross rent, minus the home’s full payment. A positive result offsets that home’s payment, and a negative result is added to your debts.
- If you have less than 12 months of property management experience, you need six months of that home’s payments in reserves.
- There is no minimum equity requirement.
For example, if your current home would rent for $3,600, the lender counts $2,700 (75%). Against a $2,650 payment, the result is a positive $50, so the payment drops out of your ratios. Under the previous Fannie Mae rule, and under Freddie Mac’s rules, a signed lease is still generally required, so ask which guideline your loan will use.
What loan limits apply to move up buyers in Denver?
Move up purchases in the Denver area often approach the conforming limit. For 2026, the conforming loan limit for a one unit home is $862,500 in the ten county Denver metro, $879,750 in Boulder County and $1,249,125 in Eagle County. Loans above those amounts are jumbo loans, which usually require more down, more reserves and stronger credit. A larger down payment from your current home’s equity can keep your new loan under the limit and on better terms.
How are taxes handled when you sell your current home?
If you owned and lived in your current home for at least two of the five years before the sale, you can generally exclude up to $250,000 of gain from income, or $500,000 for married couples filing jointly. Those are the current IRS limits, and you generally cannot use the exclusion if you excluded gain on another home within the prior two years.
Keeping the home as a rental changes the timing. Once you have rented it out for more than three years, you no longer meet the two out of five year test, and rental depreciation has its own tax treatment. Talk with your tax professional before you decide whether to sell or rent.
Frequently asked questions
Can I buy a new house before selling my old one?
Yes, if you qualify with both payments or your lender can exclude or offset your current payment. Lenders can exclude it once your current home is under contract with financing contingencies cleared, or offset it with expected rent if you keep it as a rental.
Do lenders count my current mortgage when I buy a new home?
Yes, unless your current home closes first or is under a fully executed sales contract with the buyer’s financing contingencies cleared. Otherwise both payments count in your debt to income ratio.
Is a bridge loan or a HELOC better for a down payment?
A HELOC is usually cheaper, but it has to be opened before you list your home. A bridge loan costs more but is built for the gap between buying and selling. Either payment counts in your ratios until your current home is under contract.
Do I need a lease to use rental income from my current home?
Under Fannie Mae’s updated 2026 policy, no. Lenders can use market rent from the appraisal or comparable rentals. Under the older Fannie Mae rule and Freddie Mac’s rules, a signed lease is generally still required.
What is a rent back?
A rent back lets you stay in the home you just sold for a short period after closing, paying rent to the buyer. It gives you access to your equity for the next purchase without having to move twice.
