Rental Property Calculator for
Oklahoma City Landlords.

Oklahoma City is one of the last cash-flow markets in the US for buy-and-hold rentals. That doesn't make it easy — it makes it possible. Here's what changes the underwriting from a generic spreadsheet.

Rent-to-price ratio still works.A $140k stabilized SFR renting at $1,400/month is a 1.0% rent ratio. Anywhere near 1.0% in 2025 is rare. Most coastal and Sunbelt markets sit at 0.5–0.7%. That ratio is what lets OKC rentals cash flow through 7% interest rates while Dallas, Phoenix, and Tampa rentals don't. The catch — that 1.0% deal isn't falling off the MLS. It comes from off-market wholesale, distressed estate sales, or BRRRR-and-hold strategy where you build the rent ratio by buying low and rehabbing into ARV.

Property tax advantage is real.Oklahoma County rentals pay roughly 1.05% effective property tax. The same $150k rental in Dallas County pays about 2.4% — $3,600/year vs. $1,575. That $2,000+ tax differential per door per year is why I run 70+ doors in OKC and not in Texas. It's also why a $1,400 rent in OKC produces real cash flow and the same $1,400 rent in Houston gets eaten by taxes alone.

Insurance is the silent line item.Oklahoma is hail and tornado country. Landlord DP-3 policies on a $150k rental run $1,200–$1,800/year, and they've been climbing 10–15% annually as carriers reprice severe weather risk. Hail damage on a flat-roof multifamily can produce a $20k claim, and your premium re-rates. Underwrite insurance at the high end of the range, not the low end. The calculator above lets you set insurance as a dollar figure, not a percentage, so use the real quoted number.

Maintenance and CapEx reserves — non-negotiable on 1960s–1985 stock. Most of the rental product in OKC was built between 1960 and 1985. That housing stock is now 40–65 years old. Roof replacement, HVAC replacement, water heater, electrical updates, and sewer lines are all approaching end-of-life on this generation. Real CapEx reserve is 5–7% of gross rent. Most online rental calculators default to 0% or 2%. That gap is where landlords build phantom cash flow and then get punched in the face the year the AC dies in July.

PM cost — 8–10%, sometimes 6% on volume.Local OKC PM companies are typically 8–10% of collected rent. Some will negotiate 6–7% for a portfolio over 20 doors. There's also usually a setup fee or new-lease fee equivalent to 50–100% of one month's rent. Underwrite the new-lease fee against your real vacancy assumption — 8% vacancy on a property that turns every 14 months means you're paying that lease fee almost every year. PM tools that say "just use 8%" without that nuance miss real economics.

The OKC rental checklist.Three signed-lease comps in the same zip code at similar bed/bath count and finish level. Property tax pulled from the Oklahoma County Assessor (not the realtor's guess). Insurance quoted on the actual property, not estimated. Vacancy set against the specific neighborhood's turnover history. Maintenance and CapEx at 5%/5% minimum. PM at 8%. DSCR calculated at the real refi rate, not yesterday's rate. Hit those and OKC rentals still produce 8–12% cash-on-cash all day.
