Modeling a 15 year hold when the only cost I control is the tax bill

Question

Looking at 38 acres about 25 minutes past the last subdivision on the highway. Ask is $4,100 an acre, so roughly $156k. The listing says it carries an agricultural valuation and taxes ran about $600 last year. The appraiser's site shows market value on the parcel at a level that would put the bill near $4,900 if that valuation went away.

My thesis is 12 to 15 years before the utility district reaches it. What I can't get comfortable with is how to set the appreciation hurdle. Do people model this against the tied-up capital, against the tax drag, or both? And how are you handling rollback recapture if the county decides my use doesn't qualify, or if I sell to a buyer who won't keep it in ag? I'd rather price that in now than find it at closing.

The number to clear isn't the purchase price, it's the purchase price plus everything the hold costs you before you sell.

Run both tax cases. Fifteen years at $600 is about $9,000 nominal. Fifteen years at $4,900 is $73,500 and rising, because as development approaches, the county's market value on that parcel rises with it. So the ag valuation is close to half the deal's economics. Before you sign, get the county's qualification test in writing: minimum acreage, what activity counts, how many years of prior use they require. That test varies by state and often by county, and a change of ownership is a common moment for the appraiser to re-examine it.

Rollback recapture works roughly like this in the states that have it. When the use changes or the land passes to a buyer who won't keep the qualifying use, the taxing authority collects the difference between the ag bill and what the market-value bill would have been, for a lookback period, usually with interest. Who pays it is a contract term, so put it in the purchase agreement and have a tax professional in your state confirm the mechanics before you rely on any of it.

Then the capital. $156k sitting for fifteen years at 5% somewhere liquid roughly doubles, to about $324k. That's your real floor, plus taxes on the gain when you sell.

The thing that actually breaks these exits is access. If that parcel reaches the highway through a path everyone has used for forty years without a recorded easement, a builder's attorney finds it in the first week of diligence and re-trades you or walks. Get access documented on paper while the current owner is still alive and cooperative.

Whose cattle or hay keeps the ag valuation alive after you buy? If there's a grazing lease you inherit, that's a tenant on your land with whatever rights your state gives them, and you'll want to read it before you assume the valuation transfers with the dirt.

So the tax bill goes up as the area develops even though I've done nothing to the land? That's the part I hadn't put together. It means the carrying cost is highest right before the thesis pays off.

Add closing to your model too. On raw acreage I've seen quotes for a boundary survey in the $1,200 to $2,800 range depending on acreage and how bad the old deed calls are, and if there's no recent survey the title company may except to boundary entirely. That's a one-time hit but it lands the same year as your down payment.

Fifteen years of writing checks and getting nothing back would break me. My eight units are annoying but they pay the taxes on themselves. I understand the math on your parcel, I just can't sit in it emotionally.

@cairn that's the honest constraint though. A parcel at $156k with a $600 bill is a 0.4% annual drag. If arbor can pay that out of pocket forever without noticing, the hold is survivable. If it comes out of a fund he'd otherwise need, it isn't.

Two clauses I'd want in the purchase agreement: an allocation of any rollback assessment triggered by a change in use after closing, and a seller representation about which years of ag use the county has on record. The second one is what the appraiser will look at when they test you. Sellers rarely volunteer it.

Different end of the market, but I've been looking at parcels at $900 an acre four counties out where the tax bill is $180 a year. The carrying cost is almost nothing. The problem is that nothing about the growth path is real out there, it's just cheap. arbor's $4,100 buys an actual thesis. I keep going back and forth on which risk I'd rather hold.

Is the agricultural valuation something you apply for, or does it already attach to the parcel and just continue?

monica_tran3 · Answer

@juniper it attaches to the use, not the parcel, which is why it can lapse on you. Separately, on the maintenance side, we bill about $220 for a first cut on an overgrown acre and considerably more once there's woody regrowth. If a county or an HOA sends abatement notices on vacant land, that's a cost line people forget entirely.

Comps are going to be your other headache. Raw acreage in the market I'm studying sits 200 plus days and half the transactions never show a price anywhere public, because about a dozen states don't make sale prices public at all. Pricing a 38 acre exit fifteen years out with three sales to look at is mostly judgment.
