I already own the land. Does that ruin the whole thing?

The related party thing is the part I'd chase first. Selling to an entity you control is exactly the fact pattern the acquisition rule is written about, and how it applies to your ownership percentage is a question for your accountant, not for us. I'd write down the exact question before your call so you don't spend the hour explaining background.

Setting the tax aside, four units on 3.2 acres in a small town. What's the well and septic situation, and is there sewer at the road? I've watched a rural build die on a $90k utility extension before anyone got to the fun part.

My understanding was that you just hold anything inside a zone for ten years and the gain comes out clean. Is that wrong?

@vellum I think that's wrong in two ways. You have to have a capital gain from something else and roll it in within a window, and the tax free part applies to the appreciation on the new investment, not on whatever you already had.

@plumb has it. The land you've owned since 2019 has its own basis and its own future gain and none of that is what the program touches. The program is about the money you put in from a separate sale.

Question for the room since I'm studying this stuff anyway. If the tract falls off the map on January 1, 2027, and @parcel invests in November 2026, is the investment stuck to the old tract designation or does it evaporate? I've seen people argue both ways online and neither side cited anything.

@halyard the general shape is that designation is tested when the fund makes the qualifying investment, so a 2026 investment in a 2018 tract is measured against that tract's status at the time. I've seen that stated by several people who ought to know and I still wouldn't act on it without written confirmation from a professional. The reason it matters here is that the enhanced benefits the 2025 law added attach to the post-2026 investments in the newly designated tracts, so investing in 2026 and investing in 2027 are not the same deal even if the building is identical.

Four units in a small town on the edge of nowhere. Who manages it? I ask because I do this for a living and rural four units are the hardest thing in my book to staff, the vendor bench is thin and every trip is 40 minutes each way.

@trellis that's the part I always forget exists until someone says it out loud.

$80k of gain buying you a four unit build in 2026 dollars. What's your total budget and where's the rest coming from? Because $80k is a down payment and a bit, and the tax structure doesn't do anything about the construction loan you'd still need.

Small town rents are the thing I'd nail down before any of this. I look at low price point rural markets constantly and the spread between what a new build costs and what a new build rents for out there is brutal. You can spend $180k a door and find the market pays $950. Do you have four comparable new units within 20 miles to point at?

Went through this a second time before replying. So the sequence is: sell stock, gain exists, gain goes into a fund inside a window, fund buys or builds qualifying property, hold. And @parcel's problem is that step four wants property the fund purchased from a stranger and he's the stranger. Have I got that right?

@juniper that's the shape of it as I understand it. The land can sometimes get folded in, and there is separate language about unimproved land and what counts as substantially improving it, which is exactly the sort of thing that turns on the specific facts. @parcel this is a paid-advice question, and it's the kind where the answer is worth what the hour costs.

@vellum I want to come back to your question because I think a lot of people believe that version. Buying a rental inside a designated tract with ordinary savings gets you exactly nothing from this program. No gain rolled in, no benefit. All you've done is buy a house in that neighborhood, which might be a fine idea on its own merits and has nothing to do with the tax code.

The other thing worth getting straight is that you'd be forming a fund and taking on the fund's ongoing obligations, and the 2025 law expanded what funds have to report. For an $80k roll into a four unit build, ask your accountant what the annual compliance cost looks like before you fall in love with the idea. I've seen small structures where the accounting ate the benefit.

Four units in a thin rural market also means your screening pool is four households deep and one bad one is 25% of your income. Not a tax point, just the thing I'd worry about.

@parcel do you actually want to build, or do you want the tax outcome? You've held that land clean and unlevered for seven years and now you're contemplating a construction loan, a fund entity, an improvement deadline, and four tenants, all triggered by a stock sale. Those are two different lives.

@arbor said the thing I was circling. The stock sale is the only fixed event here. Everything else is you deciding to become a developer this year, and the calendar is making that choice look urgent when it isn't.
