Investing in Dubuque, IA — Market Analysis
Dubuque is one of the lower-basis entry points in Iowa, with a median home price around $215,000. Dubuque is an urban infill market where small multifamily and converted stock dominate. Per-door rents run higher than the metro average, but so do turnover, maintenance reserves, and the spread between gross and effective rent.
Buying a rental property in Dubuque on a DSCR loan means putting a minimum of $43,000 down (20% of purchase price), leaving a loan amount of $172,000 at 80% LTV. At current DSCR investor pricing near 7.50%, principal and interest on that loan runs about $1,203 per month. Add Dubuque County property taxes of roughly $267/month and landlord insurance of about $86/month, and your all-in PITIA lands near $1,556/month. That PITIA figure — not the P&I — is what the lender divides your rent into.
A long-term lease in Dubuque should generate roughly $1,525/month in gross rent. Against a PITIA of $1,556, that produces an estimated DSCR ratio of 0.98x. That falls just short of the 1.0 minimum. This is a very common outcome in Dubuque and it does not kill the deal: moving to 25% down ($53,750) cuts the payment enough to close most of the gap, and several shelves will fund down to 0.75 with a rate add-on.
If you intend to operate the property as a short-term rental, estimated gross nightly revenue in Dubuque is around $2,300/month across a full year. Lenders do not credit gross STR revenue dollar-for-dollar — they typically haircut it 25%–30% for vacancy, cleaning, platform fees, and management. Applying a 28% haircut gives an effective $1,656/month, or a DSCR ratio of 1.06x. On a short-term rental basis the deal clears the threshold, though lenders will want twelve months of documented revenue or an AirDNA/market study to credit it.
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 Dubuque specifically, effective property tax on investment property runs around 1.49% of value annually — about $3,204 a year at the median price — and landlord insurance near $1,032 a year.
On return metrics, Dubuque pencils to an estimated cap rate of 5.28% using a 62% NOI margin, and a gross rent multiplier of 11.7. Monthly cash flow on a long-term lease at 20% down is estimated at $31 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.
