Rental / DSCR in St. Charles

Not really, and the data is one-sided. In 2024 HMDA records for St. Charles County, 2-to-4 unit properties made up about 0.46% of 1-to-4 family loan originations (89 of 19,147 records), against roughly 2.4% statewide and 15.4% across the river in the City of St. Louis. This is a detached single-family rental market, city by city, not a duplex or small-multifamily market. Underwrite the county for the SFR it has, not the small-multifamily deal another metro would offer.

The city levy is the smallest part of the bill; the school and fire district carry it. St. Charles County levies no county general-revenue property tax, and worked effective rates on identical market value range from about 1.13% in Weldon Spring (no city levy) up to about 1.37% in St. Charles city, a 21% spread driven by which school district and fire district the parcel sits in, not which city. Cities in this county straddle school and fire boundaries, so pull the parcel's own tax account before you underwrite a purchase, rather than assuming a city-wide rate.

It depends on the city, and the rules are not uniform across the county. St. Peters requires a re-occupancy inspection on every change of tenant in a non-owner-occupied home, with life-safety violations cured before anyone moves in. O'Fallon runs rental inspections under city code and charges a per-unit fee before scheduling. Wentzville, Lake Saint Louis, Cottleville, Dardenne Prairie and Weldon Spring have no verified rental occupancy ordinance either way, so confirm the current requirement with the city before you close on a rental in one of those five.

Plan for a long-term lease, not a nightly-rate pro forma. The city of St. Charles caps short-term rental permits at 0.15% of housing units, restricts them to the Extended Historic Preservation district, and its own page states the city is at its cap and not accepting new applications for residentially zoned units. No short-term rental ordinance was located for St. Peters, O'Fallon, Wentzville or Lake Saint Louis, and unincorporated county legislation to license short-term rentals was tabled in 2026 rather than adopted. A whole-house short-term rental also risks reassessment out of the 19% residential class into the 32% commercial class plus the county's commercial sur tax. This program qualifies on the property's cash flow, and any short-term income considered is subject to underwriting, not assumed as rent.

Yes, and they often sit at the Recorder of Deeds, not in city ordinance. St. Charles County's subdivision regulations require a recorded trust indenture on developments with common ground, and because most of the county is platted post-1980 subdivisions, many target parcels carry leasing restrictions written into that recorded indenture rather than into any city's rental code. Pull the recorded indenture on the specific parcel before you assume a rental is permitted; a subdivision-level restriction can bind regardless of what the city otherwise allows.

No, and the discount depends on which jurisdiction the parcel sits in. An estimated 43% of St. Charles County lies in a FEMA-mapped floodplain, with the Mississippi and Missouri rivers backing water up interior creeks well inland of the riverbanks. FEMA's Community Rating System gives unincorporated St. Charles County a class 6 rating worth a 20% flood insurance discount, while O'Fallon carries a lower class 9 rating worth a 5% discount, and St. Charles city, St. Peters, Wentzville, Lake Saint Louis, Cottleville, Dardenne Prairie and Weldon Spring are not on FEMA's CRS list at all, meaning no CRS discount on a policy written there. Price flood coverage against the parcel's actual jurisdiction, not the county average.

A DSCR (debt service coverage ratio) loan qualifies on the property's rental income instead of your personal income, so there are no W-2s or tax returns required. We compare the rent, from a signed lease or the appraiser's market-rent estimate, against the monthly payment. A DSCR of 1.00 means the rent covers the payment, and we lend with a DSCR as low as 0.75.

Our rental program starts around 5.50% interest-only, with 30-year fixed and 5/7/10-year ARM options, for a single property or a whole portfolio. The lowest pricing goes to strong credit, lower leverage, and a DSCR above 1.20; your quote depends on the file and is subject to underwriting.

We finance up to 80% loan-to-value on a purchase, with rate-and-term and cash-out refinances available, on loan amounts from $100K to $3M. Cash-out leverage is typically a little lower than purchase. The property's cash flow and your credit set your final leverage.

We start at 640, and the best pricing goes to strong credit. Because the loan qualifies on the asset, your score affects your rate and leverage more than whether you are approved.

Yes, short-term rentals are considered. We can underwrite using market or projected rents, and the property still needs to meet our DSCR. Tell us how the property is operated so we can structure it correctly.

Long-term rental loans usually carry a prepayment penalty, commonly a step-down such as 5/4/3/2/1. We offer flexible prepay structures, including buying down to a shorter penalty for a slightly higher rate, and we will lay out the options on your term sheet.
