Small Multifamily Cap Rates, Rent Rolls, and Lender Requirements for 5-8 Units

Cap rate (capitalization rate) is probably the single most important number for evaluating a multifamily investment. Its the rate of return the property generates based on its income, and its how investors and lenders measure whether a deal is priced fairly.

The formula is: Cap Rate = Net Operating Income (NOI) / Purchase Price

So if a 6 unit building generates $60,000 a year in NOI and you're buying it for $750,000, the cap rate is 8%. That means for every dollar you invest, the property produces 8 cents in annual income before debt service.

What's a "good" cap rate depends entirely on the market. In expensive coastal cities like San Francisco, LA, or New York, cap rates on small multifamily run 4-5.5%. In the Midwest and Southeast markets, you might see 7-10%. The lower the cap rate, the more expensive the property is relative to its income. But lower cap rate markets often have stronger appreciation potential, while higher cap rate markets offer better cash flow.

For 2026, we're seeing small multifamily cap rates in the 5.5-9% range across most markets. Interest rates have compressed cap rates somewhat because higher financing costs mean investors need more income relative to the purchase price for the deal to cash flow.

One mistake new multifamily investors make is comparing cap rates across different markets without adjusting for risk, growth potential, and expense structures. A 9% cap rate in a declining market with high crime isn't the same as a 6% cap rate in a growing metro area with strong job growth. Context matters more than the number itself.

The rent roll is the most important document you'll deal with on a multifamily transaction. Its a spreadsheet or report that shows every unit in the building, the tenant name, the lease start and end dates, the monthly rent, any concessions or discounts, and the security deposit amount.

Lenders use the rent roll to verify the property's income. A clean, well documented rent roll makes the lender's job easier and speeds up your approval. A messy or incomplete rent roll raises red flags and can delay or kill the deal.

Here's what a strong rent roll looks like. Every unit has a tenant (or is clearly marked vacant with the market rent listed). Lease terms are at least 12 months (month to month tenants are okay but lenders prefer annual leases). Rents are at or near market rate for the area. Security deposits are collected for each unit. There are no unusual concessions like free rent or deeply discounted rates for friends and family.

If you're buying a property where the rent roll has issues, that's not necessarily a dealbreaker but you need to know how the lender will view it. If rents are below market, the lender might use current rents for their analysis (which could hurt your DSCR). If units are vacant, the lender might use a reduced income figure. If tenants are on month to month leases, some lenders count that as higher risk.

When you're building your own rent roll for a property you already own, be meticulous. Include every detail. List market rents alongside actual rents so the lender can see the upside potential. Note any recent renovations that justify higher rents. Include utility responsibility (who pays water, gas, electric) because this affects the operating expense calculation.

Net Operating Income is the number that drives everything in multifamily lending. Its the income the property generates after all operating expenses but before debt service (mortgage payments).

NOI = Gross Rental Income - Vacancy Reserve - Operating Expenses

Operating expenses on a small multifamily property typically include property taxes, insurance, property management (usually 8-10% of collected rent), maintenance and repairs, landscaping, pest control, water/sewer if the landlord pays, garbage removal, common area utilities, legal and accounting, and a capital expenditure reserve (usually 5-10% of income set aside for major repairs).

Most lenders calculate an expense ratio to check if your operating expenses are realistic. For small multifamily properties, a typical expense ratio is 35-50% of gross income. If your expenses are significantly lower than this range, the lender will probably adjust them upward because they know you're not accounting for everything.

One of the biggest debates in multifamily underwriting is the vacancy factor. Even if your building is 100% occupied right now, lenders will apply a vacancy factor (usually 5-10%) to account for turnover, non-paying tenants, and downtime between leases. In markets with very low vacancy rates, some lenders will use 5%. In softer markets, 8-10% is more common.

Capital expenditure reserves are another area where investors and lenders sometimes disagree. You might think $500 per unit per year is enough for capex. The lender might use $800-1,200 per unit per year based on the age and condition of the property. Older buildings with deferred maintenance will have higher capex assumptions.

The resulting NOI is what the lender uses to calculate your DSCR and determine if the property can support the loan. A higher NOI means a higher DSCR which means better pricing and more favorable terms.

Appraisals on 5+ unit properties are fundamentally different from single family appraisals and they cost a lot more. Understanding the process helps you avoid surprises.

A commercial multifamily appraisal uses three approaches to value. The Income Approach is the most important one. The appraiser estimates the property's value based on the income it produces, applying a market cap rate to the NOI. This is why your rent roll and operating expenses matter so much because they directly feed into the appraised value.

The Sales Comparison Approach looks at what similar properties have sold for recently. Finding true comparables for a 6 unit building is harder than for a single family home because there are fewer transactions. The appraiser might use sales from a 10-20 mile radius and adjust for differences.

The Cost Approach estimates what it would cost to rebuild the property from scratch minus depreciation. This is usually the least relevant for investor purchases but appraisers still include it.

The cost of a commercial multifamily appraisal runs $3,000-5,000 and takes 2-4 weeks to complete. This is one of the biggest timeline drivers in the lending process. Some markets have fewer qualified commercial appraisers which can push the timeline even longer.

A few things that can cause appraisal issues on small multifamily: deferred maintenance that the appraiser flags as a condition (you'll need to repair it or escrow funds), rents that are significantly above or below market (the appraiser will note this), below market occupancy (reduces the income approach value), and environmental concerns like old heating oil tanks or lead paint.

If the appraisal comes in lower than expected, you have options. You can renegotiate the purchase price, bring more cash to closing, challenge the appraisal with additional comparable data, or walk away if the contract allows it. Working with a lender who has experience with multifamily can help you anticipate appraisal issues before they become problems.

Before you even talk to a lender about a 5-8 unit deal, you should have a clean analysis that shows you understand the property's financials. This is what separates investors who get quick approvals from ones who go back and forth for weeks.

Start with the rent roll. List every unit, the current rent, and the market rent. Calculate total gross income using actual rents. Apply a realistic vacancy factor (5-10%). This gives you effective gross income.

Then list all operating expenses. Be thorough: taxes, insurance, management, maintenance, utilities you pay, landscaping, pest control, legal, accounting, and capex reserves. Subtract total expenses from effective gross income to get your NOI.

Now calculate the cap rate by dividing NOI by your purchase price. Compare this to cap rates on similar properties in the area. If your cap rate is significantly different from the market, figure out why. Maybe the rents are below market (upside opportunity) or maybe the expenses are unrealistically low (your actual NOI will be lower).

Calculate your projected DSCR by dividing the annual NOI by the annual debt service (your total loan payments for the year based on the expected loan amount, rate, and term). Most lenders want to see 1.20-1.25 or higher.

Put all of this into a one page deal summary. Include the property address, unit count and mix (how many 1BR, 2BR, etc.), current occupancy, gross income, expenses, NOI, cap rate, purchase price, proposed loan amount, and projected DSCR. Hand this to the lender on your first call and watch how much faster the process moves.

Lenders respect investors who come prepared. It shows you've done your homework and reduces the risk of surprises during underwriting. The investors who get the best terms and fastest closings are the ones who present their deals professionally from day one.
