Riverton is two housing markets inside one set of city boundaries. Modern subdivisions on quarter-acre lots finance like anything in South Jordan. Then there is the Riverton that existed before the southwest valley filled in: half-acre, acre and five-acre parcels with barns, shops, arenas, pasture, irrigation turnouts and animal rights going back generations.
Those second properties are where the loan gets interesting. Almost everything that goes wrong here, a short appraisal, a late septic condition, a rollback tax nobody budgeted for, traces back to the land rather than the borrower, and is predictable if somebody looks at the parcel first.

Buyers arrive having been told conventional financing stops at five acres, or ten, or that FHA will not go past two. It is one of the most persistent myths in Utah real estate.
The agencies publish no maximum lot size. Fannie Mae’s guidance is that a large-lot property is eligible as long as the appraiser can develop a credible opinion of value from comparable sales and the property is residential in nature. Freddie Mac reads the same way; FHA requires the site be typical for the area.
What happens instead is that individual lenders add overlays. A bank funding mostly tract housing may cap itself at five or ten acres because its appraisal panel does not want the work. The loan officer says “that is the rule,” and from inside that shop it is, which is the practical case for using a broker. A four-acre parcel with a barn goes to a lender whose panel handles that property type routinely, rather than one that fights it and then declines.
The appraiser has to find sales of similar properties, similar land, improvements and use, and reconcile them. In a subdivision that is trivial. On a three-acre horse property the set may be four sales, two over a year old and one in Bluffdale. So the appraisal takes longer, adjustments are larger and more subjective, and the defensible value has a wider range. That cuts both ways: a well-documented reconsideration of value has better odds here.
If there is no acreage cap, what are underwriters looking at? The relationship between site value and total value. A residential mortgage is secured primarily by a dwelling, so a property that is mostly land behaves more like a land loan.
Be skeptical of what you read here. No bright-line percentage in agency guidelines automatically disqualifies a property. The 30% and 35% figures floating around come from lender overlays, not Fannie Mae or FHA rulebooks. What is true: a high land-to-value ratio invites scrutiny and usually triggers a request for the appraiser to support the site value.
A high ratio gets approved with data. If the appraiser can show that buyers in this segment genuinely pay that much for dirt, demonstrated with land sales and improved sales showing the same pattern, the ratio is a market characteristic rather than a red flag. Reported with no support, the file stalls. In Riverton the question comes up most on a modest older home sitting on several acres.
Appraisers assign limited contributory value to outbuildings. Contributory value is what the improvement adds to market value in the eyes of buyers: not cost, not replacement cost, not what the seller thinks. A 40-by-60 insulated shop with concrete, power and a bathroom can cost well into six figures to build. In the appraisal it may show up as a modest five-figure adjustment.
The reason is comparables again. Supporting a large adjustment requires paired sales proving the market paid the difference, and those are hard to assemble. Arenas, round pens and pole barns get treated more conservatively still, because the buyer pool is smaller.
Sellers price outbuildings at cost; appraisers value them at contribution. When a listing is priced at market for house and land plus most of what the seller spent on the barn, the appraisal has a real chance of coming in low. That is market value working as defined.
Decide your appraisal-gap ceiling in advance. Conventional down payment is calculated on the lesser of price or appraised value, so a $40,000 shortfall is $40,000 of extra cash unless the seller moves. Waiving the appraisal contingency on acreage with thin comps is a much bigger risk than on a subdivision home. And confirm the outbuildings are permitted, unpermitted structures may get no value, and on FHA a structure in poor condition generates a repair condition that must clear before closing.
Riverton has a real horse tradition, and many parcels carry animal rights that newer parts of the valley do not. If you are buying to keep horses, zoning and financing are tangled together.
Verify animal rights independently. “Horse property” in a listing is marketing language. What governs is the parcel’s zoning, the animals allowed per acre, setbacks for structures housing animals, and whether subdivision CC&Rs prohibit livestock regardless of zoning. Riverton City can confirm zoning for an address. Do not rely on the flyer or the horse standing in the pasture.
Legal conforming, legal non-conforming, or illegal. A use complying with current zoning raises no issues. A use that was legal when established but no longer conforms is grandfathered: financeable on conventional and FHA, but the appraisal must address whether the improvements could be rebuilt if destroyed, and if they could not, that is a genuine problem. A use that is simply illegal, such as livestock on a parcel that does not permit them, is the one that kills loans.
Residential in character. The property must read as a residence with agricultural amenities, not a farm with a house on it; boarding, breeding and commercial training push it toward income-producing use. Price the insurance early: carriers treat barns, arenas and equine liability very differently from a standard homeowners policy, and a surprise premium changes your escrow.
On a subdivision lot, water is a utility bill. On a Riverton acreage parcel it can be a separate asset that may or may not be coming with the house. Utah water rights and irrigation company shares are property interests transferable independently of the land, typically evidenced by stock certificates. Secondary irrigation may run with the parcel, may require a connection it does not have, or may be capped at a set number of irrigated acres.
Do the rights or shares convey? The contract has to say so, shares do not automatically follow the deed. Sellers keep shares, buyers find out after closing, and the pasture they bought has no economical way to get water.
Are they appraised as part of the real estate? If the water is personal property transferred by stock certificate, it generally should not sit inside the appraised value, because the lender’s lien attaches to the real estate; if the appraisal includes it, the underwriter may require it stripped out and the value drops. If the water runs with the land and the comparables all included water, it belongs in the value.
What does title show? Ditch easements, canal rights-of-way, shared well agreements and access easements for neighboring parcels all surface here. Read the exceptions in the title commitment. If there is a shared well, confirm the agreement is recorded and covers maintenance costs and minimum flow.
Most of Riverton is on municipal water and sewer, but older parcels toward the Jordan River corridor and the Bluffdale border can still be on septic, and a few have a private or shared well. Both are financeable; both add steps.
FHA is the stricter of the two. FHA requires safe and adequate water and sewage disposal. Where a private well or septic system serves the property, the lender requires evidence the system functions and meets local health department requirements: typically a septic inspection or certification and, for a well, a water quality test, plus adequate separation between well and drain field. If the system fails, repair becomes a condition of closing.
Conventional is more flexible but not indifferent. Fannie Mae and Freddie Mac do not require an inspection on every loan; they require the property be safe, sound and structurally secure. If the appraiser observes surfacing effluent or an obviously failing system, the appraisal comes back “subject to” and you have the same requirement you would have had on FHA.
Inspect early anyway. Inspect and pump during due diligence regardless of what the loan requires, learn about a failing drain field while you still have a way out, not when the appraiser writes it up. Typical conditions are replacing a lid or riser, recertifying a neglected tank and sealing an abandoned well. Full drain field replacement is the one to fear.
There is a point at which a Riverton parcel is no longer a house with land and conventional and FHA stop fitting. It is not an acreage number but a combination of factors.
| Factor | Reads as residential | Reads as agricultural |
|---|---|---|
| Primary use | Land is personal use | Land generates income |
| Zoning | Residential or residential-agricultural | Agricultural with commercial farm use |
| Improvements | Barn, shop, arena | Silos, grain storage, processing |
| Income | Incidental hay sales at most | Reported farm income |
| Site value | Supportable by residential sales | Priced on farm productivity |
| Comparables | Rural residential sales exist | Only farm sales are comparable |
General underwriting principles, not a published checklist. Lender overlays vary.
Landing on the right side of that table means a different lender, not no lender. Farm Credit institutions lend on agricultural real estate and understand it far better than a residential shop does, and local banks frequently portfolio small-acreage loans. Expect a larger down payment and a shorter fixed period, but they close on properties an agency lender cannot take. We also place alternative and portfolio programs when the property does not fit an agency box.
Utah’s Farmland Assessment Act, universally called greenbelt, lets qualifying agricultural land be assessed on its agricultural productivity value rather than market value. The effect is dramatic: land otherwise taxed as development-ready southwest-valley acreage is taxed as pasture, and the annual bill drops sharply. Owners of larger Riverton parcels have carried greenbelt for decades.
When land is withdrawn from greenbelt, developed, subdivided, converted, or no longer meeting the qualifying tests, the county recaptures the tax savings for a look-back period, plus interest. On a parcel held in greenbelt for years, that is a large number.
A sale does not automatically trigger rollback; a change in use does. Continue the qualifying agricultural use and greenbelt can generally continue, working with the county assessor on the application. Buy intending to build or stop farming it, and the rollback is coming.
Who pays is negotiated, not assigned. Sellers expect the buyer to absorb it because the buyer changed the use; buyers expect the seller to pay because the seller took the benefit. Both are arguable. Put it in the contract.
Escrow and closing implications. A rollback triggered by your future use does not appear as a lien at closing; it arrives later. Meanwhile the lender sets your tax escrow from the current bill, artificially low under greenbelt, so you get a shortage and a payment increase at the first analysis. When we know the use is changing, we escrow to the expected post-rollback figure instead.
Utah exempts 45% of a primary residence’s fair market value, so you are taxed on 55%, and Salt Lake County’s 2025 average total rate was 1.0504%. Here is the detail nobody mentions on subdivision pages: the exemption covers the dwelling plus up to one acre. Acreage beyond that does not get it, which is why greenbelt matters so much here, and why two similar-looking parcels can have tax bills differing far more than their prices do.
| Scenario | How the land is treated | Effect on escrow |
|---|---|---|
| Subdivision home, quarter-acre lot | Entirely inside the one-acre exemption | Rate applies to 55% of value |
| Acreage parcel, no greenbelt | First acre exempted; excess acreage is not | Higher than a same-priced subdivision home |
| Acreage parcel under greenbelt | Qualifying land assessed on agricultural value | Sharply lower now; rollback exposure later |
| Greenbelt parcel being developed | Withdrawn from agricultural assessment | Escrow set to post-rollback taxes |
Tax areas vary; confirm a parcel with the county assessor.
We pre-approve acreage buyers using the actual figure for the parcel, not a county average. Utah also has no transfer tax and no documentary stamp tax, recording is a flat per-document fee whatever the parcel sold for.
Everything above applies to part of what sells in Riverton. On a twenty-year-old home near the Town Center or a newer one along the South Jordan border, none of the acreage complexity touches your file.
Conventional goes to $832,750 on a one-unit property here. Three- and five-percent-down programs are available to qualified buyers, and conventional mortgage insurance can be removed at sufficient equity, the main advantage over FHA.
FHA tops out at $637,100, roughly $107,000 below the $744,050 limit Davis and Weber County buyers get, because HUD sets FHA limits by metro area and the Ogden metro is pulled up by Morgan County. Most Riverton subdivision inventory sits under that, so FHA remains usable.
Utah Housing is the down payment assistance route. FirstHome caps Salt Lake County income at $126,100 for a one-to-two-person household and $145,000 for three or more, with a $666,600 maximum purchase price. Assistance is a 30-year fixed second mortgage: traditional lends up to 6% of the first mortgage, capped at $27,500, amortizing at your first-mortgage rate plus one percent with an 8% cap; deferred lends up to 3.5%, same cap, at 3.5% deferred simple interest with nothing due until sale or refinance. FirstHome needs a 660 score, the FHA/VA product starts at 620 and allows repeat buyers, and Freddie HFA Advantage needs 680. HomeAgain, NoMI and Score are suspended. See our Utah Housing page.
That cap covers most subdivision inventory but excludes much of the acreage market. Above $832,750, which larger west-side parcels reach, you are in jumbo territory, and a jumbo on acreage stacks two sets of scrutiny. There is no USDA in Riverton; zero down means VA or Utah Housing layered onto an FHA or conventional first.
Plenty of Riverton acreage buyers plan to split off a lot later. Two things to know.
The lender cares about parcel legality at closing. The security instrument attaches to a legally described parcel and title must insure it as a single, legally created lot. Trouble comes from properties informally divided years ago without going through the city’s subdivision process: two houses sharing one tax parcel, a home sold off by metes and bounds that was never platted, a legal description that does not match the fence line. Fixing that requires municipal action and time.
Your deed of trust encumbers all of it. When you later split off and sell a piece, that piece carries your existing lien. You need a partial release, which the lender is not obligated to give, or you refinance the retained parcel. If subdividing is central to your plan it should influence which loan you take today.
If the plan is to develop rather than sell raw ground, look at lot and land development financing for the infrastructure phase and a one-time-close construction loan to build.
We finance across the city and the southwest valley: Riverton Town Center and the older core near 12600 South and Redwood Road, the Rosecrest edge, Western Springs, Riverbend, Blackridge, the Jordan River corridor, the 12600 South corridor, the Bluffdale border, the Herriman border and the South Jordan border.
The loan questions change as you move across the city. The Jordan River corridor and the Bluffdale border bring the most acreage, septic, water share and greenbelt questions. Rosecrest and the Herriman border bring newer construction and standard conventional underwriting. The Town Center and older stretches of 12600 South are a mix.

No. Fannie Mae, Freddie Mac and FHA publish no maximum acreage. They require that the property be residential in character and that the appraiser can support value with comparable sales. Individual lenders add acreage overlays of their own, which is where the myth comes from.
Usually far less than it cost to build. Appraisers assign contributory value: what the market pays for the improvement, not replacement cost. Supporting a large adjustment takes paired sales showing buyers paid the difference. Sellers price outbuildings at cost and appraisals value them at contribution, which is why this is the most common appraisal surprise in Riverton.
Only if the purchase contract says so. Utah water rights and irrigation company shares can be transferred separately from the land, often evidenced by stock certificates rather than the deed. Get conveyance in writing, confirm whether the water is included in the appraised value, and read the title exceptions for ditch easements, canal rights-of-way and shared well agreements.
Riverton is in Salt Lake County: the 2026 conforming limit is $832,750 on a one-unit property and the FHA limit is $637,100. The FHA figure is about $107,000 below the $744,050 limit in Davis and Weber counties, because HUD sets FHA limits by metro area. Above $832,750 you are in jumbo territory, which larger acreage parcels regularly reach.
Greenbelt is Utah’s Farmland Assessment Act, which taxes qualifying agricultural land on productivity value instead of market value and sharply lowers the bill. Continue the qualifying use and that treatment can generally continue. Convert the land out of agricultural use and the county recaptures the prior savings plus interest as a rollback assessment. Who pays is negotiated in the contract, so ask before due diligence expires.
Not automatically. FHA requires safe and adequate water and sewage disposal, so the lender will want evidence the system functions and meets local health department standards, typically a septic certification and a water quality test. Conventional does not require an inspection on every loan, but if the appraiser observes a problem the appraisal comes back subject to repairs.
There is no acreage number that triggers it. Underwriters look at whether the primary use is residential or income-producing, how the parcel is zoned, whether the improvements are personal-use barns or commercial farm structures, and whether residential comparable sales exist. On the agricultural side the answer is a different lender: Farm Credit and local portfolio lenders write these loans.
Yes, within the county limits. FirstHome caps income at $126,100 for a one-to-two-person household and $145,000 for three or more, with a maximum purchase price of $666,600, which covers most subdivision inventory but excludes much of the acreage market. Assistance is a 30-year fixed second mortgage, up to 6% of the first mortgage amortizing or 3.5% deferred, both capped at $27,500.
