Every property investment is one of four shapes. Core, Core Plus, Value-Add, or Opportunistic. Each shape fits a different kind of investor. Knowing which one fits you is the first decision. Knowing which one a deal is, is the second. Two prompts pasted into Claude do both.
Big property funds sort every deal they look at into one of four categories before they buy. Each one suits a different kind of investor. There is no good or bad category, only the one that fits what you actually want.
A completed building in a proven area, fully let, throwing off rent from day one. Fits an investor who wants steady cash flow and minimal volatility. Lower return ceiling. You sleep at night.
Completed, leased, but in a community that is still maturing. Rent today, capital growth as the area builds out. Fits an investor who wants cash flow but doesn't want to leave growth on the table.
An older or underperforming building you actively improve. Renovate, reposition, push the rent. Fits an investor who has time, contractor relationships, and project-management bandwidth. The return is in the work you do.
Off-plan, pre-infrastructure, or in a brand new masterplan. No income for years. Fits an investor with a long time horizon who is comfortable carrying construction, developer, and timing risk. Maximum upside, real chance of slippage.
The classifier scores every property in your list against these four shapes. Whether you are weighing your first deal, comparing two opportunities, or making sense of what you already own, you finish with a name on every property and a clear read on what kind of investor each one fits.
One Claude conversation. You paste two things, Claude renders a dashboard. Every property scored, every property labelled, and a one-line note on the kind of investor each one fits. All on one page you can screenshot or send to a partner.
Claude Pro. $20/mo. The free tier runs the prompts but the inline artefact is less polished. Pro is the right tier.
Anything you want classified. A single deal you are weighing up, two opportunities you are choosing between, or your existing properties. One row per property, basic facts only.
Ten minutes. Five to pull the list together. Two for the prompts. Three for Claude to render.
The classifier scores the building, not your financing. Leverage is deliberately out of the framework. The same villa is the same villa whether you paid cash or borrowed 75 percent of it. Track leverage separately on your own spreadsheet.
The classifier scores each property on three things: where the building sits in its life cycle, where the return actually comes from, and how much work you have to do. Each one gets a 1 to 4. The highest score is the category. Paste this prompt into a fresh Claude chat. Claude reads the rubric, confirms in one line, and waits for your list.
Splitting the framework and the data lets you reuse the setup. You can run multiple portfolios in the same chat, each with a different paste in the second message. The framework is the operating system. The portfolio is what you load into it.
The last paragraph of the prompt locks the look. Without it, Claude defaults to a dark-mode dashboard that doesn't match anything else you make. The design directive is what makes it look like yours, not Claude's.
Send a list of whatever you want classified. One deal, two options, or twenty existing holdings. Use the structure below, fill in one row per property.
No current valuation? Leave it blank. Not sure what the rent would be after a renovation? Leave it blank. Claude flags the missing field and still classifies the property from what is there. Your first paste is fine. Your second one will be sharper.
Claude renders the dashboard inline in the chat. A risk-return bar with every property plotted, an allocation donut against the reference range used by big funds, a card per property with the three scores and the kind of investor it fits, and a comparison table grouped by category.
Ask Claude to re-classify with a different assumption (say, "what changes if I don't renovate this one") and the dashboard updates in place.
No MCPs, no plugins, no third-party tools to wire up. Two prompts and a dashboard rendered in the chat.
$20/mo. The right tier for this. Cleaner artefact rendering than the free plan, and enough message room to re-classify with different assumptions without hitting a limit.
Runs both prompts. The dashboard is less polished and you'll burn through the daily limit fast if you iterate. Fine for one classification a month.
Five minutes to pull your portfolio together. Two minutes for the prompts. Three for Claude to render. Faster on the second run because you've already got the paste.
The framework names the shape. It does not tell you which deal to buy. Three things you still own.
An Opportunistic deal at the right price is a winner. Same deal at twice the price is a disaster. This sorts strategy. It does not underwrite. Before you wire anything, run the deal through Day 14 (IC-style underwrite), Day 9 (off-plan), or Day 11 (comparables).
A villa is Value-Add because you said you would renovate it. Drop the renovation and it shifts to Core Plus. Change what you intend to do with the property and the category changes too. The "what would move this up or down" line on every card names the lever.
The classifier scores the building, not your mortgage. Two buyers holding the same Core apartment at zero and 75 percent LTV are running totally different risk books. Track leverage on your own spreadsheet.
Day 13 watches what you already own. Day 14 underwrites every new acquisition. Day 15 sorts both into the same four-style framework so you know which playbook applies. The classifier sits in front of the underwriting, not after it.
A Core deal goes through the IC stack to check rent and exit cap rate. An Opportunistic deal goes through the same stack, but you weight handover risk, developer track record, and infrastructure timing harder than yield. The category sets the question. The underwriting answers it. Same operating system, three different days, every property held to the same standard.
Ten minutes in, you've got a risk-return spectrum, an allocation donut against the institutional benchmark, a card for every property with its scores and a one-line action, and a table grouped by category. Paste a new acquisition into the same chat and watch the dashboard re-render with the new property in it.
The portfolio review stops starting with "is this a good deal?". It starts with "where does this land, and what does that mean for what we already hold?". That's the shift Day 15 ships.
Every prompt in this 30-day series is one capability. FourthspaceOS bundles all of them into a single product: underwriting, comps, market research, deal sourcing, portfolio tracking, and investor reporting. The product runs natively on the same Anthropic agents and plugins you are learning to use this month.
Waitlist members get founding pricing, early access, and one new prompt delivered each day for the next 30 days.

Send them this page. Ten minutes and every asset in their portfolio has a name. Every future acquisition gets one too. That's the part that actually compounds.
