Investing in Derby, KS — Market Analysis
Derby is one of the lower-basis entry points in Kansas, with a median home price around $270,000. Derby is a suburban growth market, which typically means single-family stock, longer average tenancies, school-district-driven demand, and lower turnover cost than urban infill. Suburban DSCR deals tend to underwrite cleanly because the rent comps are homogeneous.
Buying a rental property in Derby on a DSCR loan means putting a minimum of $54,000 down (20% of purchase price), leaving a loan amount of $216,000 at 80% LTV. At current DSCR investor pricing near 7.50%, principal and interest on that loan runs about $1,510 per month. Add Sedgwick County property taxes of roughly $317/month and landlord insurance of about $108/month, and your all-in PITIA lands near $1,936/month. That PITIA figure — not the P&I — is what the lender divides your rent into.
A long-term lease in Derby should generate roughly $1,525/month in gross rent. Against a PITIA of $1,936, that produces an estimated DSCR ratio of 0.79x. That is well below the 1.0 threshold on a long-term lease, which is typical for a market at this price point. Financing here generally works one of three ways — a larger down payment, a no-ratio DSCR product, or qualifying on short-term rental revenue instead of long-term rent.
Two Kansas-specific items to build into your model: Kansas assesses residential property at 11.5% of market value and county appraisers are required to review values annually, so a purchase price above the prior assessment usually shows up on the next notice of value — underwrite the tax line off what you pay, not the seller's bill. In Derby specifically, effective property tax on investment property runs around 1.41% of value annually — about $3,807 a year at the median price — and landlord insurance near $1,296 a year.
On return metrics, Derby pencils to an estimated cap rate of 4.20% using a 62% NOI margin, and a gross rent multiplier of 14.8. Monthly cash flow on a long-term lease at 20% down is estimated at $411 negative. Negative cash flow at 20% down is common in appreciation-led markets; investors here typically increase the down payment, buy below median, add a unit, or run the property short-term to close the gap.
