1031 exchange; subdivide the intended purchase property?

That separation isn't a complication you're adding; it's the thing that makes the whole plan work, because a 1031 only ever defers the gain on property you hold for investment. The ground you put your house on can't ride inside the exchange no matter how you draw it up — it has to be bought with money that never touches the exchange, which is exactly what you're already reaching for with the personal mortgage. So you've got the shape of it.
Where a plan like this is won or lost is somewhere most people never think to look, and it isn't the subdivision. It's value, not acreage. The exchange only defers in full if the investment parcel you buy is worth at least what your relinquished rental nets you, and you roll every dollar of the proceeds back in. If the farmhouse on two acres comes in under the rental you're selling, that shortfall isn't a rounding error — it's boot, it's taxable, and it lands right on top of the depreciation you've been recapturing all these years. So the two-and-fourteen split shouldn't be drawn where the prettiest homesite is. It should be drawn where the dollars have to land to keep you out of boot — and sometimes that means more ground on the investment side, or the vacant parcel carrying the weight, with your homesite carved smaller than you first pictured it.
Then there's the clock, which is the part that quietly kills these. The day you sell, you're on forty-five days to identify and a hundred and eighty to close — and a seller subdividing raw land, with the survey and the plat and the county's blessing, can run well past that. If the new parcel doesn't legally exist when your clock runs out, the whole thing comes apart in your hands. So the subdivision needs to be locked, or well down the road, before you ever sell the property you're relinquishing — or you look hard at a reverse exchange, where you take the new place first and sell after, and buy your way out from under the timing for a little more cost.
Two smaller things, once those are handled. Building your own home on the parcel you exchanged into is the classic way people lose the "held for investment" test without ever meaning to, so keep the house strictly on the side that never touched the exchange. And the basis you carry over from the old rental is what sets your depreciation, and your recapture, down the road on the farmhouse — better to map that now, with your eyes open, than to run into it at a closing table years from now.
None of this is too complicated to do. It's only complicated to do in the wrong order — and the right order falls out of your actual numbers and your actual timeline, not the other way around. I came up as a broker and a deal analyst before I ever sat behind the CPA license, so I tend to read these while the deal's still in the model instead of after the year's already closed on it. If it'd help, send me what the relinquished property nets and what the parcels are worth, and I'll lay out how the split and the timing would have to line up. No obligation either way.

You've actually got the right instinct here. Splitting the investment piece off from the piece you'll build your home on is exactly what makes this work, because a 1031 only defers the gain on property you're holding for investment, so the land your house sits on has to be bought with money that stays outside the exchange rather than rolled into it. The bigger thing to watch isn't the acreage, it's the value: to fully defer you generally need the investment parcel you buy to be worth at least what your relinquished rental nets you, and you have to reinvest all the proceeds, or the shortfall becomes taxable boot on top of your depreciation recapture. Timing is where these usually fall apart too. You've got 45 days to identify and 180 to close, and a seller subdividing raw land may not get the new parcel legally created in time, so either lock the subdivision down before you sell or look at a reverse exchange, and keep your future home strictly on the non-exchange parcel so you don't undercut the held-for-investment requirement. It's all doable in the right order, but the exact path really depends on your specific numbers and timeline, so run it by your own CPA before you commit.

@Scott E. Fleming is exactly right! When it comes to the portion of the property being held for investment, your main focus is meeting the reinvestment requirements by purchasing as much or more investment property than what you sold to defer all of the tax. Any additional amount of purchase can be used for anything you want, including building a new primary. I don't think you'll necessarily have to set aside a portion with a separate deed if you want to build a primary. You can if you'll get favorable financing. But your CPA can allocate portions of the property accurately to set up the depreciation tables for the investment portion. And the rest for your personal residence.
This also works for investors who want to reinvest into multi-family and purchase a duplex or triplex but also want to live in one of the units. It still works, but it is split between the units being held for investment, which can be depreciated and 1031d, and the other unit held for personal use.

The subdivision idea is workable, but the 1031 side needs careful structuring given what you're planning to do with each piece afterward. A 1031 exchange requires the replacement property to be held for investment or business use, so you'd want to exchange into the farmhouse rental portion only, the 2 acre parcel with the existing duplex, that's a straightforward like kind swap from your current rental into this one. The moment any part of that acquired parcel gets used to build your personal residence, that portion falls outside 1031 treatment entirely, so keeping the subdivision clean between the investment parcel and the personal use parcel is what protects the exchange, not just a paperwork formality.
The right of way detail matters more than it might seem too, if the 14 acre parcel you're buying personally has any right of way running through or tied to the 2 acre 1031 parcel, that can complicate the qualified use test on the exchanged property, worth getting a real estate attorney and your CPA to review that specific arrangement before you're locked into the subdivision as structured. Also keep in mind the farmhouse and land both carry your existing rental's basis after the exchange, so future depreciation, and any eventual capital gains if you sell the 2 acre parcel down the line, carries forward the deferred gain from what you're selling now.

@Karen F., hi. Here are some key points to consider;
Feasability: The strategy is complex due to mixed-use intentions, but achievable with proper structuring.
1031 Rules: The portion designated for your personal residence does not qualify for 1031 tax deferral, as exchange properties must be held for business or investment.
Subdivision Solution: Subdividing the 16-acre parcel helps cleanly separate the investment duplex from the personal build site, though it requires precise coordination with a Qualified Intermediary (QI).
Next Steps: Consult a real estate attorney and your QI early to ensure proper title separation and compliance before going firm.

Quote from @Karen F.:
I have located a farm I'd like to buy. It is off market, and has an existing farmhouse duplex on site, which is currently rented. I want to both retain the farmhouse as a rental, and also, build a new home and live in it on the remainder of the property. currently, the land is on two parcels: a 16 acre parcel with the aged farmhouse, and a larger vacant land parcel. Ideally, I would sell an existing duplex or single family rental to 1031 exchange into the farmhouse parcel, and buy the second parcel for personal use. I have a few issues I'd need to navigate; one most important: I'd rather build on the farmhouse parcel, for its beauty, as well as for the fact it is closer to infrastructure. I thought possibly the sellers could subdivide the 16 acres into 2 and 14 acres, and let the remainder 14 acres of that parcel have a right of way? Is this just too complicated? I'd 1031 into the farmhouse on 2 acres, and get a personal mortgage for the remainder? Is this just too complicated? Any advice appreciated.
@Karen F. one thing nobody's touched on yet that might actually solve your value problem for you: look at a construction/build-to-suit exchange instead of a straight swap into the 2-acre parcel as-is.
@Scott E. Fleming. nailed the real risk here, it's value not acreage, and if the farmhouse parcel comes in under what your relinquished property nets, that gap is boot whether the acreage split feels fair to you or not. A construction exchange lets you park the replacement parcel with an accommodation titleholder, use your exchange proceeds to fund capital improvements on the investment side (new well, updated systems, maybe even a small ag building, whatever adds legitimate value), and then take title once the improvements are done. That can close the value gap without you having to fight the sellers for more acreage than makes sense for the split.
The catch, and this trips people up constantly, is that the improvements have to be complete and title transferred within your 180 day window, not just started. Everyone remembers the 45 day ID deadline, way fewer people realize the construction has to actually be finished by day 180 too. If the sellers are slow getting the subdivision through the county, you could end up racing two clocks at once, the subdivision timeline and the construction timeline, which is a real risk on top of what @Dave Foster and @Ashish Acharya already flagged about the subdivision needing to exist before you're locked in.
Given all the moving pieces (subdivision timing, value allocation, right of way on the personal parcel, and now a possible improvement exchange on top of it) this is a case where the sequencing really does determine whether it works, exactly what Scott said. Worth mapping out the actual numbers with your CPA and QI before you go firm on the purchase agreement.

The most important issue may be completing the subdivision and establishing defensible values before the relinquished property is sold. Surveys, approvals, access, utilities, financing, and legal parcel creation can all take longer than expected. I would map the investment parcel and personal parcel separately, obtain professional valuations, and make the purchase agreement contingent on the required approvals. That gives the qualified intermediary, lender, attorney, and tax adviser a defined structure to evaluate.
