Question 1

Who's the typical buyer for an SBA-financed, owner-occupied building in St. Charles County?

Accepted Answer

The suppliers and vendors that sit around the county's two biggest employers. GM's Wentzville Assembly plant runs roughly 4,124 jobs building the Chevrolet Colorado, GMC Canyon and the Express/Savana vans, and GM announced $157 million for a paint-shop modernization and a 28,000 square foot expansion in July 2026, an 18-month build that will pull contractors and suppliers along with it. Mastercard's O'Fallon technology campus, its largest US data center, employs more than 4,000 people and anchors a professional-services and vendor base around it. A business that has outgrown a lease near either anchor, or along the I-70/I-64 corridor between them, is the classic SBA 504 or 7(a) candidate.

Question 2

Does buying a commercial building in St. Charles County cost more in property tax than a comparable house?

Accepted Answer

Yes, close to double. Missouri assesses commercial real estate at 32% of market value against 19% for residential, and St. Charles County adds a separate 0.5300 sur tax on top for Sub-Class 3 commercial parcels. Worked on the O'Fallon tax rate: a commercial building runs about 2.20% of market value a year against roughly 1.21% for a residential parcel on the same rate stack, a ratio of 1.82. That gap runs for the life of a 25-year SBA loan, so it belongs in the pro forma next to the debt service.

Question 3

St. Charles County taxes new residential construction as bare land until it's occupied. Does that help my SBA-financed commercial building too?

Accepted Answer

No, and this is a distinction worth getting right before you underwrite the deal. The county's occupancy-based assessment rule, RSMo 137.082, applies only to newly built residential property; it is taxed as land until occupancy or the fourth January 1 after completion. Commercial and agricultural property in St. Charles County is assessed on its January 1 status every year regardless of occupancy, so a new SBA-financed commercial building carries full improved-value tax exposure from day one, with no occupancy-timing relief to plan around.

Question 4

I want to buy and renovate a building in downtown St. Charles with an SBA loan. Is there anything that slows that down?

Accepted Answer

If the building sits in one of the city's historic districts, yes: budget the calendar, not just the money. The city of St. Charles has designated 26 individual landmarks and 6 historic districts, including South Main and Frenchtown, covering more than 3,000 properties. Any exterior construction, alteration or demolition on a building in one of those districts needs a Certificate of Appropriateness from the Historic Landmarks Preservation and Architectural Review Board, which meets once a month, generally the third Monday. A missed submittal adds roughly four weeks of hold before a building permit can even be pulled.

Question 5

Should flood risk factor into where I site an SBA-financed building in St. Charles County?

Accepted Answer

Yes, and it varies a lot by jurisdiction. An estimated 43% of St. Charles County sits in a FEMA-defined flood-vulnerable area, with the Mississippi and Missouri rivers accounting for roughly 30% of that and interior creeks the other 13%, so a site miles from either river can still sit in a mapped floodplain. Flood-insurance discounts differ sharply by city: unincorporated St. Charles County carries a FEMA Community Rating System class 6, a 20% discount, while O'Fallon sits at class 9, a 5% discount, and St. Charles city, St. Peters, Wentzville, Lake Saint Louis, Cottleville, Dardenne Prairie and Weldon Spring don't appear on the CRS list at all, so a floodplain parcel inside those city limits earns no discount.

Question 6

How much do I need to put down on a St. Charles County owner-occupied building, and how big a loan can you place?

Accepted Answer

As little as 10% down, and loan sizes from $350,000 to $5 million and up. SBA financing runs up to 90% of the purchase price on terms as long as 25 years, so on a $600,000 St. Charles County building that's up to $540,000 financed and $60,000 from you (600,000 x 90% = 540,000). Under 13 CFR 120.910, borrower contribution steps up to 15% if the business has under two years of operating history or the building is single-purpose, and 20% if both apply, and under 13 CFR 120.131 the business has to occupy at least 51% of an existing building, or 60% of new construction with only 20% permanently leasable. If you're buying to lease the space out rather than run your business from it, our commercial bridge program is the investor path instead. Subject to underwriting.
