Property flipping, without borders

Buy right.
Build tight.
Exit clean.

The universal rules behind a disciplined property flip—plus the legal, tax and market questions that must be answered locally.

Underwrite the downsideUse sold evidence, slower timelines and cost ranges—not the rosiest case.

The twelve rules

These principles are portable. Apply them in every market, then have qualified local professionals validate the details.

Buy from evidence, not excitement

Anchor after-repair value to recent, nearby sold comparables with similar size, use, condition and tenure. Active listings show competition; they do not prove value.

Deal testCan you defend the exit price with at least three relevant closed sales?

Write the complete cost stack

Count acquisition tax, legal fees, financing, utilities, insurance, permits, labor, materials, selling fees, transfer taxes, vacancy and the cost of time.

Deal testWould a six-month delay still leave a worthwhile profit?

Protect a real contingency

Older assets, unfamiliar construction and limited inspections require larger buffers. Contingency belongs in the budget—not in the hoped-for profit.

Starting rangeOften 10–20% of renovation cost; raise it when uncertainty rises.

Prove title and possession

Confirm the seller’s authority, liens, easements, tenure, boundaries, occupancy, inheritance claims and the legal path to vacant possession before closing.

Never assumeA recorded sale does not always mean immediate or uncontested possession.

Obtain permission before demolition

Map planning approval, building permits, heritage limits, condominium or strata consent, contractor licensing and required inspections into the schedule.

Red flagThe budget depends on unapproved added area, a new use or structural work.

Renovate for the buyer—not yourself

Match finish level to the local buyer, climate, maintenance expectations and comparable sales. Spend first on safety, function, layout and visible defects.

Scope testDoes each upgrade protect value, speed the sale or lift price beyond its cost?

Control scope, schedule and cash

Use written drawings, quantities, inclusions, milestones, change-order rules and inspection points. Link payments to verified progress, not promises.

Site rulePhotograph hidden work before walls or floors are closed.

Finance the delay you did not plan

Know the loan term, draw process, interest basis, extension fees, recourse and currency exposure. Keep liquidity outside the project budget.

Stress testModel rates, exchange rates or holding time moving against you.

Insure the actual project

Ordinary homeowner cover may exclude vacant buildings, construction or commercial activity. Confirm site, liability, flood, wind, earthquake and worker coverage where relevant.

Proof pointGet coverage and exclusions in writing before work begins.

Underwrite taxes before you buy

Short holding periods may be treated as business income rather than capital gains. Include purchase, ownership and sale taxes, plus entity and cross-border consequences.

Professional checkHave a local tax adviser model the transaction—not just the annual return.

Build two credible exits

Primary resale is not a plan by itself. Test rental cash flow, wholesale or assignment rights, refinance availability and a discounted quick-sale price.

Walk-away triggerIf every fallback loses more than your risk limit, the entry price is too high.

Document the handover

Keep permits, invoices, warranties, inspections, disclosures and before/during/after records. Disclose known defects as local law requires.

Exit testCould a buyer, lender and regulator trace what changed and who approved it?
II

The deal math

A screening rule is not an offer. Price from your required profit backward, using costs that fit the actual jurisdiction and project.

Maximum allowable offer

Start with a conservative after-repair value. Then subtract every cost, your target profit and a contingency before deciding what you can pay.

MAO = ARV − renovation − transaction costs − holding & finance − taxes − contingency − target profit
The “70% rule” is only a filter.It is common in parts of the United States, but it ignores local taxes, fees, financing and market velocity. Return on costExpected profit ÷ total project cost. Also model annualized return when timelines differ.

Non-purchase costs$152,000
Maximum offer$283,000
Target margin on ARV13.0%

Screening estimate only. Verify all figures locally before making an offer.

III

Local questions, by region

These are investigation prompts—not summaries of law. Countries, states, provinces, cities and even buildings can impose different rules.

Americas

Rules can differ sharply by federal, national, state or provincial, municipal and association level.

Title & saleWhich title system, escrow/notary process, disclosures and transfer taxes apply?
PermittingDo municipal permits, zoning, historic review or HOA/condo approvals affect the scope?
Tax statusWill repeated or short-term sales be taxed as business/dealer income?
ForeclosureAre there redemption rights, occupied-property risks or unpaid municipal/association claims?
IV

Four gates before “go”

A deal advances only when every gate has a defensible answer. “We will figure it out later” is a failed gate.

1

Legal gate

Clear authority to buy, renovate, possess and resell—with title, restrictions and approvals understood.

2

Physical gate

Condition, scope, code path, contractor capacity and timeline independently tested.

3

Financial gate

Conservative value, complete costs, available cash, contingency and return hurdle all reconciled.

4

Exit gate

Target buyer, route to market, disclosures, sale costs and a credible second exit documented.

Title or seller authority cannot be proved.The profit exists only at the highest possible resale price.Essential work depends on approvals not yet tested.The budget omits taxes, finance or selling costs.Your only contractor estimate is a verbal total.A delay would exhaust your liquidity.
