Investing in Marshalltown, IA — Market Analysis
Marshalltown is one of the lower-basis entry points in Iowa, with a median home price around $145,000. Marshalltown is a smaller Iowa market. Entry prices are low and gross rent-to-price ratios are among the best in the state, but appraisers have fewer rent comps to work with, and a single vacancy is a much larger share of annual income than it would be in a metro.
Buying a rental property in Marshalltown on a DSCR loan means putting a minimum of $29,000 down (20% of purchase price), leaving a loan amount of $116,000 at 80% LTV. At current DSCR investor pricing near 7.50%, principal and interest on that loan runs about $811 per month. Add Marshall County property taxes of roughly $180/month and landlord insurance of about $58/month, and your all-in PITIA lands near $1,049/month. That PITIA figure — not the P&I — is what the lender divides your rent into.
A long-term lease in Marshalltown should generate roughly $1,275/month in gross rent. Against a PITIA of $1,049, that produces an estimated DSCR ratio of 1.22x. That clears the standard 1.0 minimum, which is the threshold most DSCR shelves require for their base pricing. There's not much cushion, so a tax reassessment or an insurance increase could push the file into a lower tier — worth stress-testing before you write the offer.
Two Iowa-specific items to build into your model: Iowa counties reassess in odd-numbered years and the state's residential rollback percentage is reset annually, so the taxable share of an investment property's value moves even when the assessed value does not — pull the current rollback and the local levy before you finalize a rental pro forma. In Marshalltown specifically, effective property tax on investment property runs around 1.49% of value annually — about $2,161 a year at the median price — and landlord insurance near $696 a year.
On return metrics, Marshalltown pencils to an estimated cap rate of 6.54% using a 62% NOI margin, and a gross rent multiplier of 9.5. Monthly cash flow on a long-term lease at 20% down is estimated at $226 positive. A cash-flowing file at 20% down is the exception in most markets right now, and it gives you room to absorb a rate that doesn't come down.
