Five scattered houses mean five roofs, five tax bills and five tenants calling about five water heaters. One larger building can be simpler to run, and an exchange is how many investors make the move.
In short: Many investors sell several single-family or 2-4 unit rentals and combine the proceeds into one larger 5+ unit property through a 1031 exchange. LendingStreet finances the replacement property with multifamily loans underwritten on the building's net operating income, so the financing plan has to be ready to close inside the exchange deadlines. The widely known deadlines are 45 days to identify replacement property and 180 days to close, and they are generally not extended because a loan is late. The exchange itself is run by a qualified intermediary and governed by tax rules, so work with a qualified intermediary and your tax advisor; we do not give tax advice.
LendingStreet is an investment property financing company. Nothing on this page explains how your exchange will be taxed or whether it will qualify. Exchange rules have details that depend on your situation, and many decisions must be made before your first sale closes.
Talk to a qualified intermediary and a tax advisor before you list any property. What follows is how the financing fits around a trade-up, in general terms.
A portfolio of small rentals is a good way to start. As it grows, management becomes scattered: different neighborhoods, different contractors, different insurance policies. A 5+ unit building concentrates operations under one roof and often makes professional management more practical.
There are trade-offs. One building means less geographic spread, and a multifamily property is valued and financed on its income, not on comparable house sales. Investors who trade up should be ready for a different kind of underwriting.
Your current rentals were probably financed on DSCR loans that compare each property's rent to its payment. Multifamily loans for 5+ units are underwritten on net operating income: gross rents minus vacancy and operating expenses. The building's value is also driven largely by that income.
That means the documents and the questions change. Expect a rent roll, a trailing operating statement and a closer look at expenses, management and the physical condition of the building.
| Item | Small rentals (1-4 units) | Multifamily (5+ units) |
|---|---|---|
| How the loan qualifies | Property rent vs. the full payment (DSCR) | Net operating income vs. debt service |
| How value is set | Mostly comparable sales | Mostly income, supported by sales |
| Key documents | Lease or market rent estimate | Rent roll and operating statements |
| Expense review | Taxes, insurance, HOA | Full operating expenses, including repairs and management |
| Third-party work | Appraisal | Appraisal and often property condition review |
The widely known 1031 deadlines are 45 days from the sale of the relinquished property to identify replacement property in writing, and 180 days from that sale to close. The two periods run at the same time. In some cases the 180-day window can end earlier because of your tax filing date, so ask your tax advisor.
A multifamily purchase often takes longer to underwrite than a single house, because there is more to review. That is why the financing should start before you sell, not after you identify.
| Stage | Exchange step | Financing step |
|---|---|---|
| Before any sale | Engage a qualified intermediary; plan the sales | Share your scenario and target buildings; get options |
| Day 0 | First relinquished property closes; funds go to the QI | Have entity documents and statements ready |
| By day 45 | Identify replacement property in writing | Apply on the top target; order appraisal and reports |
| Days 45-150 | Due diligence on the building | Review rent roll, operating statements, inspections |
| By day 180 | Close on the replacement | Close the multifamily loan; QI wires exchange funds |
Trading several rentals into one building raises practical timing questions. If your sales close on different dates, ask your qualified intermediary how the deadlines apply, because each sale may carry its own clock depending on how the exchange is structured.
From a financing view, the cleanest plan has the sales close near each other and well before the replacement closing. Staggered sales can work, but they compress the time you have to finance the building. Keep the financing team informed of each sale date so the loan timeline matches.
Tax advisors often describe a general rule of thumb for deferring all of the gain: buy replacement property of equal or greater value, reinvest all the net proceeds, and replace the debt paid off on the sales with new debt or added cash. Whether and how that applies to you is a question for your tax advisor.
Financing is where debt replacement becomes concrete. When you sell three rentals with mortgages, those loans are paid off. The new multifamily loan, plus any added cash, is what replaces that debt. Your tax advisor can tell you what amount matters for your exchange, and the financing team can size the loan with that target in mind, as long as the building's income supports it.
This example is illustrative and not a quote. It is not tax advice. An investor sells three rentals for $450,000, $400,000 and $350,000, a total of $1,200,000. The mortgages paid off at the sales total $600,000, and sample selling costs are $72,000. Net proceeds held by the qualified intermediary are $528,000.
The investor buys a 16-unit building for $2,400,000. Assume a multifamily loan at 75% of the price, or $1,800,000. The $600,000 down payment comes from the $528,000 in exchange funds plus $72,000 of added cash, with closing costs on top. The new loan of $1,800,000 is larger than the $600,000 of debt that was paid off, and the building's price is larger than the combined sale prices.
The 16 units rent for $1,550 each, or $24,800 a month and $297,600 a year. Assume 40% of gross rent goes to vacancy and operating expenses, leaving net operating income of $178,560. At a sample 7.0% on a 30-year amortization, annual debt service is about $143,705, a coverage ratio of about 1.24x. The loan would need to meet the program's coverage requirement for that building.
| Item | Before (three rentals) | After (16-unit building) |
|---|---|---|
| Property value | $1,200,000 combined | $2,400,000 |
| Debt | $600,000 paid off at the sales | $1,800,000 new loan |
| Cash into the purchase | $528,000 held by the QI | $528,000 exchange funds plus $72,000 added |
| Units | 3 | 16 |
| Coverage | Each property on its own | About 1.24x on building NOI |
Under an exchange deadline, the building you choose affects how fast it can be financed. A stabilized property with steady occupancy, clean books and leases that match the rent roll usually moves faster than one with heavy vacancy or missing records.
A value-add building with empty units or below-market rents may not support a long-term loan at the price you need. Some investors finance that kind of purchase with a multifamily bridge loan and refinance after the units are renovated and leased. If you go that route, confirm with your tax advisor how it fits your exchange.
Ask sellers for the rent roll, operating statements and any recent inspection reports before you identify, so you can screen out buildings that will struggle to finance in time.
The lender is financing the building's income, so the building has to carry its debt. Your experience managing rentals helps, and so does a plan for professional management if you have not run a property this size.
Starting early is the most useful thing you can do. Our financing team reviews the scenario and comes back with 2-3 options, ideally before your first sale closes.
Many investors do. How multiple sales fit into one exchange is a question for your qualified intermediary and tax advisor. On the financing side, we finance the replacement building based on its income.
Multifamily loans usually involve more review than a single rental, including the rent roll, operating statements and condition. Start the financing before your first sale so the 180-day deadline is not at risk.
Tax advisors often describe replacing paid-off debt with new debt or added cash as part of deferring all of the gain. Whether that applies to you is a tax question. We can size the loan with your advisor's target in mind if the income supports it.
Vesting can matter in an exchange. Ask your qualified intermediary and tax advisor before choosing the buying entity. Our programs allow LLC borrowers.
The deadlines are generally not extended because a loan is running late. That is why identifying backup properties and starting financing early matters. Ask your tax advisor what happens if you miss a deadline.
On net operating income: gross rents minus vacancy and operating expenses, compared to the annual debt service. A rent roll and operating statements are central to the review.
Yes, if your exchange allows it. Five or more rentals can be financed together on a blanket portfolio loan with one closing and portfolio pricing.
No. We are an investment property financing company. You will need a separate qualified intermediary to hold the exchange funds.

Properties with 5+ units are commercial by definition, so they fall outside Fannie/Freddie residential programs. But at 5-20 units the loan is usually too small for institutional multifamily desks, whose minimums and timelines are built for 50+ unit assets. The result is a financing gap: too big for residential, too small for institutional.
Through DSCR-based and bridge capital sources that underwrite to the property's net operating income rather than agency checklists. Typical structures: purchase or refinance at up to 75% LTV, 5-20 units, $200K-$20M, with bridge-to-perm available for value-add and lease-up plays.
Stabilized small multifamily DSCR loans typically close in 14-21 days. Bridge structures for value-add acquisitions can close in 5-10 days, then refinance into permanent DSCR financing after stabilization.
No. These programs underwrite the property's income (NOI / DSCR), not your tax returns. LLC borrowers are standard, and there is no W2 requirement.
Mixed-use with a residential majority (for example, apartments over retail) can be placed through commercial and mixed-use capital sources through the same LendingStreet application, with custom terms up to $5M+.
