How to Calculate ROI on a Montgomery Rental Property: A Real-World Guide

For InvestorsMar 25, 2026Phil James, Principal & CEO

Every investor asks the same question before buying in Montgomery: "What's my return going to be?" The answer depends on which ROI metric you use — and most investors only look at one when they should be looking at three. Here's how to run the real numbers on a Montgomery rental property, with examples using actual market data.

The Three ROI Metrics That Matter

There are dozens of ways to measure real estate returns, but three metrics give you the clearest picture for a single-family rental in Montgomery:

Cap rate tells you how a property performs independent of financing. It's the baseline measure of a deal's quality.

Cash-on-cash return tells you what your actual invested dollars earn each year. This is what most investors care about because it reflects the real cash hitting your account.

Total ROI includes appreciation, principal paydown, and tax benefits on top of cash flow. This is the full picture of wealth building.

Let's break each one down with a real Montgomery example. For a deeper dive on cap rate vs cash-on-cash, see our complete comparison guide.

Example Property: 3BR/2BA in 36116

This is a typical Montgomery Section 8 investment property:

Purchase price: $110,000

Down payment (20%): $22,000

Closing costs: $3,300

Total cash invested: $25,300

Monthly rent (Section 8 FMR): $1,178

Mortgage (30yr, 7%): $585/month

Calculating Cap Rate

Cap rate = Net Operating Income / Purchase Price

First, figure your annual NOI:

Annual gross rent: $1,178 × 12 = $14,136

Vacancy allowance (5%): -$707

Management fee (10%): -$1,414

Property taxes: -$550 (Alabama has some of the lowest property taxes in the nation)

Insurance: -$900

Maintenance reserve (8%): -$1,131

Net Operating Income: $9,434

Cap Rate: $9,434 / $110,000 = 8.6%

For context, most markets in the Southeast are producing 5-7% cap rates on single-family rentals. Montgomery's 8-11% range is one of the reasons out-of-state investors are choosing this market.

Calculating Cash-on-Cash Return

Cash-on-cash return = Annual Cash Flow / Total Cash Invested

Annual NOI: $9,434

Annual mortgage payments: $585 × 12 = -$7,020

Annual cash flow: $2,414

Cash-on-cash return: $2,414 / $25,300 = 9.5%

That's $201/month in your pocket after every expense is paid — including professional management. With a DSCR loan at a lower rate, this number climbs higher.

Calculating Total ROI

Total ROI adds three components that most investors forget:

Cash flow: $2,414/year (calculated above)

Principal paydown: ~$1,800/year (the portion of your mortgage payment that reduces your loan balance — your tenant is paying this for you)

Appreciation: ~$2,200/year (conservative 2% annual appreciation on $110,000)

Tax benefits: ~$1,500/year (depreciation deduction at a 25% tax bracket — consult your CPA for your specific situation)

Total annual return: $7,914

Total ROI: $7,914 / $25,300 = 31.3%

That's the real return on a Montgomery rental — and it's why investors who understand the full picture keep buying here.

Why Section 8 Changes the Math

The example above uses a Section 8 tenant, and that matters for several reasons:

Vacancy is near zero. The MHA waitlist means replacement tenants are always available. Our vacancy allowance of 5% is conservative — many Section 8 properties experience less than 2% vacancy over a multi-year hold.

Rent is government-backed. The Housing Authority pays 70-100% of rent directly to the landlord. This isn't tenant income — it's a federal payment. This dramatically reduces collection risk compared to market-rate tenants.

Tenant retention is higher. Section 8 tenants tend to stay longer because vouchers are difficult to obtain and they don't want to risk losing their housing assistance. Longer tenure means fewer turnovers, fewer placement fees, and lower maintenance costs. Read our full Section 8 vs market-rate comparison.

The Numbers That Kill Deals

Not every Montgomery property is a good investment. Watch out for:

Deferred maintenance: A $90,000 property that needs a $15,000 roof, $8,000 HVAC, and $5,000 in plumbing is really a $118,000 property — and the cap rate just dropped below 7%.

Flood zones: Properties in flood zones require additional insurance that can add $1,200-$2,400/year to operating costs, destroying cash flow.

Bad neighborhoods: Some zip codes have higher crime, lower tenant quality, and faster depreciation. Low price doesn't always mean high returns. Check our zip code analysis before buying.

Overestimating rent: Don't use Zillow rent estimates. Use actual HUD FMR data for Section 8 properties and verified comps for market-rate.
