The ground work
County records to closings to entitlement and build to hold. 36 tracts · 212 lessons on the ground work, all free.
1Compliance & safe AI use (free)7 lessons›
Valuation restraint, owner privacy, and what's never safe to paste. The skeleton, practiced to reflex.
2Workflows & automation5 lessons›
Design a repeatable task into an AI workflow. With a human approval gate exactly where it belongs.
3Claude & Cowork mastery3 lessons›
One platform, mapped to the job: a Project for your standing context, a Cowork skill for a repeatable prompt, MCP connectors for your live inbox and calendar.
4Brief it like a new acquisitions VA6 lessons›
The transfer area. You already brief help; the only new idea is that this help cannot see anything you did not paste, and will fill a gap rather than show one.
5Pick the county before the parcel6 lessons›
Screen a county against your own gates, read its own rules and records back in quotes, and keep a dated one-pager, so the choice rests on what the county published and never on a market the model imagined.
6Build the list, then scrub it6 lessons›
Tag, stack, skim, score and reconcile a pulled list without changing a cell, so every letter traces back to the county export and every flag stays a check to run, not a fact about an owner.
7Mail that gets a phone call6 lessons›
Plain letters and postcards where every name, figure and claim comes from your own export and pricing sheet, so a drop of hundreds carries no small inventions.
8Reach them without mail6 lessons›
Texts, voicemails, calls and ads drafted as legal acts, screened against consent, do-not-call and opt-out duties, and handed to counsel to clear before anything sends.
9Find the owner nobody can find6 lessons›
When the letter comes back and the number is dead, build the search from county and court records, and never let the model hand you a name, an heir or a signer it cannot trace to a document.
10The seller call6 lessons›
Prepare, rehearse and log the conversations that decide a deal, saying only what your own file supports and clearing every call and follow-up before it happens.
11Price it without inventing a number6 lessons›
You bring the recorded sales and the model lines them up, shows its arithmetic and tests your figure, but the number on the offer is always yours.
12Diligence before the wire6 lessons›
Every check takes its status from a record you pulled, every silence becomes an order, and the title company, surveyor, county and counsel confirm what the model never clears.
13Close it6 lessons›
Close the tract on paper you can point to, so the seller understands what she is signing and the recorded deed says what the contract said.
14List it so it sells6 lessons›
Sell the tract on facts you can prove, so every listing, photo, direction and letter holds up when a buyer checks it against the record.
15Terms without trouble6 lessons›
Carry the paper on your own numbers and the documents' own words, with every note, notice and default step drafted for counsel before it reaches a buyer.
16Keep what you made6 lessons›
Turn your closing statements, ledgers and notes into questions your CPA, intermediary or attorney can answer in one pass, and never let the model be the accountant.
17Run it like a shop6 lessons›
Get the process out of your head and into other hands, with every SOP, hire, record and weekly number traced to what you actually do and what you actually counted.
18From flip to development6 lessons›
Stop asking what a tract would sell for and start reading what it is allowed to become, with every standard quoted, every date counted in the open and every determination left to the office that makes it.
19Buy the classification6 lessons›
You are paying for what the land is allowed to become, so every lesson reads the use table, the program rules or the map layer itself and never takes a flyer's word for any of it.
20Assemble the block6 lessons›
Find out who really owns each lot, reach them like a neighbour you will know for years, and schedule every takedown only from what the signed agreements say.
21Title, survey and the whole block6 lessons›
Read every chain, exception, survey call and easement across the lots you mean to combine, and send each open item to the professional who can close it.
22Value land you mean to hold6 lessons›
Commission, sort and question the valuation work on land you hold, so every number in the file keeps its source and none of them comes from the model.
23Hold it6 lessons›
Carry costs, interim income, entity records, dates and the exchange clock across everything you own, each figure traced to a document and every gap left open for the professional who closes it.
24Contract to close6 lessons›
Read every instrument between the letter of intent and the wire to what it actually says, and find the gap before the money moves.
25Finance the land6 lessons›
Size the land loan, compare the term sheets and keep the covenants on a calendar, with every figure quoted from the lender's own paper and the arithmetic left to a calculator.
26From holding to building6 lessons›
Decide whether a parcel you hold should be built on, then turn the land, the program and the first studies into paper a partner, a lender and a planning office can read, with every figure traced to a document and nothing promised about the hearing.
27Pick the market like a fund6 lessons›
Read the forecast, the absorption, the pipeline, the rents and the sale comps you were handed, quote every figure to its page, and never let the model extend a trend past what the report prints.
28Select the site against the program6 lessons›
Hold every site up to your own program box, cell by cell, so a zoning label never passes for an entitlement, a brochure never passes for power, and the empty cells become your diligence order.
29Entitle it6 lessons›
Read the agenda, the staff report, the conditions, the will-serve letters and the studies for what the record actually says, and walk into the hearing prepared without ever being told how the vote will go.
30Underwrite the development6 lessons›
Build the pro-forma, back into the land price, stress it, underwrite and value the stabilised building and take it to committee, with every number your own and every return computed in your model.
31Capital, project by project6 lessons›
Raise equity one project at a time with every return labelled a target, every approval and utility letter quoted, and every page drafted for securities counsel's review, never called compliant.
32Construction and permanent debt6 lessons›
Take a build-to-hold project to construction and permanent lenders from the owner's chair, quoting approvals, utility letters and term sheets as written and never calling a site entitled or served.
33Pre-lease and lease-up6 lessons›
Lease a building before it stands by quoting the plans, the approval and the utility letters, leaving the rent to you and every missing spec as a gap to fill.
34Lease documents6 lessons›
Read every lease, SNDA, estoppel and sublease on the site you built from the owner's chair, quoting the paper and handing its meaning to counsel.
35Operate and hold6 lessons›
Check the manager's statements, rolls, reconciliations and bids against the records before your name goes on them for partners, lenders and tenants.
36The buying week5 lessons›
Audit the buying week before you hand the first task over, catch the acreage the deed does not say, cost the mail drop, wrap the day into the parcel file, and say who you are with the real dates.
