Conventional Investment in St. Charles
Conventional investment property loans across St. Charles County.
We fund conventional investment loans up to 80% LTV on non-owner-occupied 1-4 unit properties, with a 30-year fixed or ARM, credit from 580, and full income documentation, for purchase or refinance. Across St. Charles County, values run from the older river towns up to the high-basis newer submarkets, so the loan amount a documented file needs varies sharply by which of the eight cities you're buying in. Because full-documentation underwriting weighs your qualifying payment, the county's school-and-fire tax stack, which swings by city, feeds directly into that math. Business-purpose lending only, subject to underwriting.

How it works
For investors who qualify conventionally, this is usually the lowest-cost long-term money on a buy-and-hold. We help you weigh it against our DSCR and bank-statement programs so the loan matches your file and your goals.

Local FAQ
Conventional Investment in St. Charles, answered.
St. Charles County home prices range from the $300,000s to the $600,000s. Does that change what a conventional investment loan looks like here?
Yes, the loan size a documented file needs shifts a lot by city. Zillow put July 2026 mid-tier home values at $326,460 in St. Peters and $350,422 in St. Charles city, against $503,964 in Cottleville and $641,599 in Weldon Spring. At up to 80% LTV, an 80% purchase loan on a St. Peters home runs roughly $261,000 against roughly $513,000 on a Weldon Spring home (326,460 x 0.80 = 261,168; 641,599 x 0.80 = 513,279, our arithmetic on the Zillow figures). Send us the address and the price and we'll tell you which structure fits the file. See conventional investment terms.
Does the county's property tax stack change how much house I qualify for on a full-documentation loan?
It can, and it varies by which school and fire district your parcel sits in, not just the city. Worked effective rates on market value range from about 1.13% in Weldon Spring to about 1.37% in St. Charles city, a 21% spread on an identical purchase price. St. Charles County itself levies no general-revenue property tax at all: the county's own 2025 chart lists it at 0.0000, with the school district and the fire district carrying the bill instead. Because a conventional file qualifies on your documented income against a full PITI payment, that tax swing changes the payment your file has to support before you ever look at the rate. Confirm the parcel's actual school and fire district before you count on an estimate. See conventional investment terms.
St. Charles County's rental yields run modest. When does conventional financing beat a DSCR loan here?
When the rent doesn't carry as much leverage as your income can. Gross rent divided by home value across the county's eight cities runs roughly 4.6% to 6.2%, well under St. Louis city's 8.6%, our arithmetic on the same Zillow rent and value series. A DSCR loan sizes leverage off that rent coverage, so on a lower-yield St. Charles County file it can cap the loan amount below what a documented borrower could otherwise support. If your tax returns or pay stubs qualify you, conventional financing often reaches higher leverage or a lower cost than a DSCR file sized on rent alone. We'll run both and show you the numbers. Compare against our DSCR program.
Does conventional investment financing here work on a duplex or small multifamily, or just a single-family house?
In practice, almost always a single-family house. 2024 HMDA data for St. Charles County shows 2-4 unit properties at just 0.46% of 1-4 family loan records, one-fifth Missouri's statewide share and about one-thirty-third of St. Louis city's. This program covers non-owner-occupied 1-4 units, but the county's actual rental stock is overwhelmingly detached houses on subdivision lots, not duplexes or fourplexes. Underwrite the file you're actually buying, not a multifamily assumption this market doesn't support. See conventional investment terms.
I'm buying through an LLC in St. Charles County. Does Missouri's residential mortgage licensing law apply to my conventional loan?
No, because the loan isn't a "residential mortgage loan" under Missouri's definitions. Missouri's licensing statutes turn on loan purpose and, under the older definition, on a natural-person borrower, not on property type: a business-purpose loan to an LLC on a non-owner-occupied St. Charles County rental falls outside RSMo 443.703(30) and 443.803.1(20). That keeps a Missouri residential mortgage broker license out of the picture for this kind of loan. Confirm this with your own Missouri counsel before closing. See conventional investment terms.
Can my LLC negotiate the rate and terms freely on a St. Charles County conventional investment loan?
Yes, Missouri frees the rate and terms in writing for an LLC borrower on a business-purpose loan. RSMo 408.035 lets parties agree in writing to any rate of interest, fees and other terms and conditions on a loan to an LLC or for a business purpose, clearing Missouri's usual ten-percent usury ceiling. A St. Charles County LLC borrowing for a non-owner-occupied rental clears this on both counts. Get the agreed terms in writing; that's the condition the statute sets. See conventional investment terms.
FAQ
Conventional Investment questions, answered.
What is a conventional investment property loan?
It is standard, competitively priced financing for a non-owner-occupied investment property, the long-term loan you take when your file fits the conventional box. It usually carries a lower rate than a bridge or DSCR loan, in exchange for full documentation.
How is it different from a DSCR loan?
A conventional loan qualifies on your documented personal income and credit, while a DSCR loan qualifies on the property's rent. Conventional pricing is often lower if you can document your income and you are within the limit on financed properties; DSCR is easier to scale and skips the income docs. We compare both and put you in the one that fits.
How much do I need to put down?
Plan on roughly 20% to 25% down on an investment-property purchase, with the best pricing at lower leverage and higher credit. Cash-out refinances are typically capped a bit lower than purchases.
What credit score do I need?
Conventional investment financing generally wants a credit score around 580 or higher, and your rate improves meaningfully as your score and reserves go up. We will tell you up front where your file lands.
What can I use it for?
Purchases, rate-and-term refinances, and cash-out refinances on non-owner-occupied 1-4 unit investment property. If you will live in the property, that is owner-occupied financing, which we refer to a trusted partner rather than originate here.
What documents are required?
Because it is fully documented, expect to provide income verification, tax returns, bank statements, and the standard conventional paperwork. If that documentation is a hurdle, our DSCR and bank-statement programs are the no-tax-return alternatives.

About the local figures on this page
Local rules move. Every tax rate, fee, ordinance and market figure here comes from a primary source and carries the date we read it, and we correct them as the rules change. Where a number is mid-change or we could not verify it, we say so rather than guess. Before you commit a budget, confirm anything that drives it with the city or county, and talk to your attorney or CPA on questions of law or tax.
