How to buy an apartment complex comes down to a sequence: you set a clear buy box, line up financing, find and underwrite deals, make an offer with a letter of intent, complete due diligence, close the loan and hand the property to a manager on day one. The order matters, and skipping a step is how owners overpay. Here is how each step works.
This guide uses "apartment complex" and "apartment building" for the same thing: a multifamily property, commonly five or more units.
How to Buy an Apartment Complex: The Nine Steps Before and After Closing
Buying an apartment complex is a sequence: buy box, financing, search, underwriting, offer, due diligence, closing, takeover and the first 90 days. Each step feeds the next, and a weak one shows up later as a surprise at the closing table or in the first month of ownership.
Step 1: Set Your Buy Box
A buy box is a short written list of what you will and will not buy. It keeps you from chasing every listing that crosses your inbox.
Write down your target market, unit count range, building age and class, and how much work you will take on. A 12-unit building that needs paint and a new roof is a different job from a 90-unit property that is full and stable. Add the one thing you will not touch, such as heavy deferred maintenance or a neighborhood you cannot visit.
Your buy box also sets your search. If you are looking in Reno, Sparks or Carson City, you can drive the area, talk to brokers and learn the streets. That local knowledge is hard to get from a spreadsheet.
Step 2: Line Up Financing Before You Make Offers
Financing decides what you can buy and how fast you can move. Talk to lenders before you tour a property, so a seller sees an offer from a buyer who can close.
Apartment loans are not home mortgages. They are underwritten mostly on the building's income, and the lender will look at your experience and finances too. The main routes are:
- Agency loans. Fannie Mae and Freddie Mac back multifamily loans made by approved lenders. Fannie Mae's Multifamily Selling and Servicing Guide has a full chapter on its small mortgage loans, with sections on occupancy, property income analysis and replacement reserves. It shows what an agency lender checks before it funds.
- Bank and credit union loans. These come from a lender's own balance sheet. They can be flexible on structure and speed, and terms vary a lot by lender.
- Small-balance loans. Agencies and banks both offer products sized for smaller buildings, where a large agency loan would not fit.
- HUD and FHA programs. These insure loans on existing rental housing and have their own requirements and review process, so ask a lender who works with them whether your property fits.
Ask each lender for a written term sheet: loan amount, term, amortization, whether the loan is recourse, prepayment rules and reserve requirements. Compare those, not just the interest rate. We do not quote rates here because they change constantly. Get a current quote from the lender.
Step 3: Find Apartment Buildings for Sale
Deals come from three places: listings, brokers and your own outreach.
Public listing sites show what is on the market, but good deals often move through broker relationships before they are widely advertised. Tell two or three local multifamily brokers your buy box and what you can close. Brokers send deals to buyers who are specific and who follow through.
You can also write to owners directly. Owners of older buildings sometimes sell when a long hold ends or when management has become a burden. A short, respectful note with a clear way to reach you costs little.
Step 4: How to Underwrite an Apartment Building
Underwriting is how you decide what a property is worth to you. It turns the seller's numbers into your numbers. You need two documents from the seller.
The rent roll lists every unit, its resident, rent, lease dates and any past due balance. The T12 is the trailing twelve months of income and expenses. Put them side by side. Does the rent roll's income match what the T12 says was collected? Are the expenses complete, or is the seller leaving out management fees, payroll or reserves?
Then build your own view of the property: realistic rents, vacancy, expenses and the cost of the work you plan to do. A multifamily underwriting model gives you a consistent way to run every deal through the same questions, so a good presentation does not talk you into a bad building.
Two cautions. First, a seller's pro forma is a sales document. Treat it as a claim to test, not a fact. Second, we do not quote returns here. What an investor calls a good return depends on their financing, their time horizon and their risk. Decide yours before you look at a deal.
If you want a second opinion on a property you are considering, our multifamily deal review is built for that.
Step 5: Make an Offer With a Letter of Intent
A letter of intent (LOI) is a short, usually non-binding document that states your price, deposit, due diligence period, financing plan and closing timeline. If the seller accepts, the attorneys draft the purchase and sale agreement.
Keep the LOI clear and honest. Make the due diligence period long enough to do the work in Step 6. Ask up front for the documents you will need: leases, the rent roll, the T12, tax bills, utility bills, service contracts and any open repair or insurance claims. A price that looks high but comes with a long review period can still be a good deal, because you can renegotiate if the building does not match its paperwork.
Step 6: Complete Due Diligence
Due diligence is where you confirm the property is what the seller said. You are checking three things: the money, the building and the paper.
- The money. Verify the rent roll against leases and bank deposits, and the T12 against statements and invoices.
- The building. Hire a licensed inspector to look at the roof, structure, plumbing, electrical, HVAC and common areas, and walk a sample of units, including the worst ones.
- The paper. Review title, survey, zoning, leases, service contracts and any open code or insurance issues. Your attorney should lead here.
If you find something, you have three options: renegotiate the price, ask the seller to fix it, or walk away. Our multifamily due diligence checklist lists what to verify, item by item.
Step 7: Finalize Financing and Close
While you do diligence, your lender will order its own reports, commonly an appraisal and an environmental review, and finish underwriting. Respond to lender requests fast. Many closing delays come from missing documents.
Before closing, confirm the final numbers: loan amount, reserves the lender will hold, prorations for rent and deposits, and who holds resident security deposits after closing. Your attorney and title company handle the legal transfer. Read the closing statement line by line.
After Closing: Taking Over and Managing the Property
The last two steps start the day you close.
Step 8: Take Over the Property
The day you close, the work starts. Line up your property management plan before closing, not after. Decide who will collect rent, answer maintenance calls and talk to residents on day one.
Plan the handoff. Gather the keys, access codes, vendor list, warranties and utility accounts. Send residents a clear notice about who to pay and who to call. Confusion in the first weeks is how you lose good residents.
Step 9: The First 90 Days With a Property Manager
The first 90 days set the tone for your ownership. A manager helps you work through them roughly in this order:
- Days 1 to 30. Meet every resident you can, walk every unit and note repairs. Confirm every lease and deposit against what the seller gave you. Set up reporting so you see the numbers monthly.
- Days 31 to 60. Fix safety and life-safety items first, then the small repairs residents have been waiting on. Review vendor contracts and utility bills for savings.
- Days 61 to 90. Compare actual results with your underwriting. Adjust the budget, set a renewal and rent plan and decide which improvements to do first.

How to Buy an Apartment Building as a First-Time Buyer
If you are buying your first apartment building, the steps are the same, but the margin for error is smaller. A few habits help:
- Start smaller than your ambition. A building you can understand end to end teaches more than a large one you cannot.
- Build the team first: a lender, an attorney, an inspector, a CPA and a property manager.
- Use the same underwriting model on every deal so you learn what normal looks like.
- Keep cash for the surprises. Every building has them.
Securities rules can apply if you raise money from other investors to buy a property. Talk to a securities attorney before you do.
Buying a Multifamily Property Takes a System
To buy a multifamily property well, run the same steps every time. The buyers who do well are rarely the ones who find the cheapest building. They are the ones who check the numbers, plan the first 90 days and walk away from deals that do not hold up.
