Core Rent vs Buy Comparison Model
Most comparisons of this kind are rigged, usually without meaning to be. They set the renter’s full annual rent against the owner’s costs after netting off rental income, and conclude that buying is dramatically cheaper. That comparison omits the largest item on the renter’s side of the ledger: the renter still has the purchase price, and it is earning something.
Here is the model done properly, on a buyer who spends three months a year in Phuket. Every revenue input below is assumed, not observed, and that is stated once here rather than qualified line by line: Thailand keeps no letting register, so the gross rental figure, the occupancy behind it and the appreciation rates in the tables further down are inputs you supply, not measurements anyone holds. The cost lines are the opposite, management fee, CAM, insurance and the furnishing cycle are all quotable from documents before purchase, and the whole point of the exercise is to see how much the answer moves when the assumed half changes while the quotable half stays fixed.
Renter. A comparable one-bedroom in Bang Tao costs roughly $2,500 a month in high season and $1,500 in the shoulder. Two high-season months and one shoulder month comes to $6,500 a year. The $150,000 that was not spent on a property stays invested.
Buyer. A $150,000 one-bedroom, occupied personally for three months and let for the other nine.
| Line | Annual |
|---|---|
| Gross rental income, assumed, at a 9-month, 8% annual rate | $9,000 |
| Management fee at 35% of gross | -$3,150 |
| Common area maintenance | -$720 |
| Insurance | -$150 |
| Furnishing refresh, amortised over five years | -$800 |
| Net rental income | $4,180 |
Now compare like with like. The renter pays $6,500 in rent and receives investment income on $150,000. The buyer receives $4,180 in net rent and forgoes that same investment income. At an assumed 4% return on the alternative investment, assumed, not observed, on both sides of this comparison: the renter’s net annual cost is $500 and the buyer’s is $1,820.
On cash cost alone, renting is cheaper. That is the honest answer, and it is the opposite of what this comparison is usually made to show.
So why does buying still win?
Because cash cost is not the whole return. The buyer also owns an appreciating asset, and the renter’s capital is doing the same thing somewhere else. The real question is which grows faster, net of what each arrangement costs to run.
Here is the five-year outcome on the same $150,000, expressed as the position you end up in. Every rate in the table is an assumption rather than a forecast, on both sides: Phuket has no transaction index, so no appreciation rate has been measured for it, and the invested-return rates are equally chosen rather than promised. The buying column assumes the $4,180 of net rent from above, roughly $4,000 in purchase costs, and about 7% in transaction costs on exit. The renting column assumes the capital stays invested and $6,500 a year of rent is paid out of income.
| Scenario | Position after 5 years |
|---|---|
| Buy, assumed appreciation 3%/yr | $178,600 |
| Buy, assumed appreciation 5%/yr | $194,900 |
| Buy, assumed appreciation 7%/yr | $212,600 |
| Rent and invest, assumed 4% total return | $150,000 |
| Rent and invest, assumed 6% total return | $168,200 |
| Rent and invest, assumed 8% total return | $187,900 |
Read the table as a comparison of rows, not as a verdict, and note that every rate in it is assumed rather than observed. On those assumptions, buying at 5% beats renting at 8%, and buying at 3% does not beat renting at 6%. The decision turns almost entirely on two numbers, neither of which anyone can promise you: what your property does and what your alternative investment does.
What the table does show reliably is that the case for buying rests on appreciation plus rental income together, not on avoiding rent. Anyone telling you that buying is obviously cheaper because rent is money down the drain has left half the arithmetic out.
And there is a third column the table cannot hold. The owner has a place that is theirs, furnished as they want it, available when they want it, without booking anything. Some buyers value that at nothing and some at a great deal, and it is a legitimate part of the decision as long as it is named rather than smuggled in as a financial argument.
Annual Cost of Renting Equivalent Property: By Budget and Area
| Area | Equivalent Rental (monthly, peak) | Equivalent Rental (monthly, low) | Annual Rent (3mo stay) | Annual Net Ownership Cost |
|---|---|---|---|---|
| Bang Tao 1BR | $2,300-$3,500/mo | $1,400-$2,000/mo | $5,900-$9,000 | $800-$1,800* |
| Kata 1BR | $2,000-$3,000/mo | $1,200-$1,800/mo | $5,000-$7,800 | $700-$1,500* |
| Kamala 1BR | $2,200-$3,200/mo | $1,300-$1,900/mo | $5,500-$8,200 | $800-$1,700* |
| Rawai 1BR | $1,500-$2,500/mo | $900-$1,500/mo | $3,900-$6,500 | $500-$1,200* |
| Nai Yang 1BR | $1,200-$1,800/mo | $700-$1,200/mo | $3,100-$4,800 | $400-$900* |
*Net ownership cost = annual maintenance fees + opportunity cost on equity, rental income received during non-occupation months
Read the last column carefully. Net ownership cost here means maintenance plus the return forgone on the equity, less rental income received while you are elsewhere. It is not comparable to the rent column on its own, because a renter holding the same capital is earning on it. Set the two side by side only after crediting the renter with that return, as in the model above.

Annual Cost of Ownership: Full Breakdown
| Cost Item | Annual (USD) |
|---|---|
| Opportunity cost on equity (4% on $150k) | $6,000 |
| Common area maintenance fees | $720 |
| Insurance | $150 |
| Furnishing refresh (amortized over 5 years) | $800 |
| Management fee (during rental months) | $3,150 |
| Total annual cost | $10,820 |
| Less: rental income (9 months, net) | -$9,000 |
| Net effective annual housing cost | $1,820 |
The $1,820 figure already includes the return forgone on $150,000 of equity, which is the largest single line in the table. Comparing it against a renter’s gross rent of $7,000-$9,000 would double-count: the renter still holds the $150,000 and it is still earning. Credit them with the same 4% and their net cost falls to roughly $500-$3,000 a year depending on the area, which is where the comparison in the model above lands.
Appreciation is where the case for buying is actually made, and it is also the input nobody can supply. On the assumed 5% a year used above, a property adds roughly $41,000 of value over five years before exit costs, against $20,900 of accumulated net rent, but the renter’s invested capital compounds too, so the gain has to be measured against the alternative rather than against zero. That comparison is in the five-year table. What no page can tell you, this one included, is which row of that table Phuket will turn out to occupy: there is no published price series for the island in which any past rate could be found, let alone a future one.
Break-Even Calculation: When Buying Definitively Wins
The comparison below credits the renter with an assumed 4% return on the $150,000 they did not spend, so both columns are net of the same opportunity cost. That rate is chosen, not measured, and moving it moves the crossover. Ownership costs rise with personal use because every month you occupy is a month the property does not earn.
| Time in Phuket per year | Renter’s net annual cost | Owner’s net annual cost | Which is cheaper on cash |
|---|---|---|---|
| 1 month | -$3,500 | $1,000 | Renting |
| 2 months | -$1,500 | $1,400 | Renting |
| 3 months | $500 | $1,820 | Renting, narrowly |
| 4 months | $3,000 | $2,400 | Owning |
| 6 months | $7,500 | $3,500 | Owning |
| 12 months full-time | $21,000 | $6,000 | Owning, decisively |
A negative figure means the renter’s investment return exceeds the rent they pay, so the arrangement is cash-positive.
The pattern is the opposite of the one usually presented. At light personal use, renting is cheaper on cash, because the property earns less than the capital would elsewhere and you are paying a manager 35% for the privilege. The crossover sits somewhere around three to four months, and past six months ownership wins clearly because renting for half the year in a resort market is expensive.
None of that settles the decision, because it ignores appreciation, which is the component that most favours buying. What it does settle is a claim you will hear frequently: that buying beats renting even at one month a year because the pool covers everything. On these assumptions it does not.
When Renting Makes More Sense?
You are in an uncertain life stage: Job change, relationship uncertainty, potential relocation, locking $150,000 into a 2-3 year off-plan purchase and a minimum 3-5 year hold is risky if your life situation might change dramatically.
You haven’t visited enough: Buying property in a market you’ve visited once carries real zone-choice risk. If you’re not sure whether Bang Tao or Kata suits your lifestyle, rent in both for 1-2 years before committing.
Your budget is too stretched: If buying requires financial strain, the psychological cost of ownership is too high. Renting while saving toward a comfortable $120,000-$150,000 budget is better than a stressed $80,000 purchase.
You need liquidity: Property in Thailand takes 6-24 months to sell. If you might need the capital in 2 years, a liquid investment is better than Phuket real estate.
Buyer scenarios: rent vs buy decision framework
Scenario A: 1-month regatta or golf tripper: Buying still wins if unit rents 11 months, but management quality determines whether away-month income is real.
Scenario B: Uncertain relocation (job change within 24 months): Renting avoids 6-24 month sale timeline, liquidity risk dominates math.
Scenario C: $400K+ villa leasehold: Rent-vs-buy math includes higher opex and thinner resale pool, often need 5+ year hold to beat luxury seasonal rents.
Insider tip: stress-test the low season hard before accepting an agent’s peak-week screenshot. No Phuket occupancy figure is published, so there is no correct number to model, which is exactly why you should run the comparison twice, once on the agent’s implied year and once on a year where the monsoon half books at half the peak’s rate, and see whether the decision changes. Rent-versus-buy spreads collapse when away-month income is overstated.
Extended 5-year comparison: $165K Kamala 1BR
The Kamala version of the same exercise, on a slightly larger ticket and a slightly weaker rental market.
| Line | Amount |
|---|---|
| Purchase price | $165,000 |
| Purchase costs, transfer fee split, legal, sinking fund | $4,500 |
| Furnishing | $16,000 |
| Net rental income, 9 months let, per year, assumed | $4,000 |
| Personal use | 3 months |
| Value after 5 years at an assumed 4% appreciation | $200,700 |
| Exit costs at 7% | -$14,000 |
| Position after 5 years | $207,200 |
Against that, a renter holding $185,000: the price plus costs and furnishing, which is the true comparison, at an assumed 6% invested return reaches $247,600, less five years of Kamala rent at roughly $6,000 a year, leaving about $217,600.
On these assumptions the renter is ahead, and the gap closes only if Kamala appreciates faster than 4% or the alternative investment does worse than 6%. The lesson is not that Kamala is a poor purchase. It is that furnishing costs and a slightly lower net rent move the answer more than most buyers expect, and that the comparison capital is the all-in figure rather than the sticker price.

Sensitivity analysis: when rent wins after stress
Every figure above assumes the property performs. Change three inputs and the case inverts.
Occupancy. The model assumes the unit earns an 8% annual rate across nine months. Stress-test that at a realised occupancy of 55 to 60% instead, a figure chosen for the test rather than measured, since none is published, and net rental income falls from $4,180 to somewhere near $2,000, roughly doubling the owner’s net annual cost. That single input moves the answer more than the choice of area does.
Appreciation. Stress-test it at zero. Over five years the buyer then ends up around $161,000 against $150,000 for a renter earning 4% and paying rent, and behind a renter earning 6%. Flat markets happen, and since Phuket publishes no index there is no way to know whether you are in one until well after the fact, which argues for treating any growth as unpriced upside rather than as part of the return.
Exit friction. Agent commission of 3-5%, withholding tax, plus specific business tax at 3.3% if you sell inside five years or stamp duty at 0.5% after, together commonly cost 5-9% of value. Selling in year three rather than year six can consume most of the accumulated advantage.
Add a 12-month sale delay on exit and 5% transaction friction, and owning only wins beyond a 36-month horizon unless appreciation makes up the difference: an appreciation figure that is assumed in every scenario here, since Phuket publishes none. Villa leasehold with $25K annual opex needs 48+ month holds to amortize friction.
Comparison with holiday-home-only buyers
The arithmetic above assumes the property is let when you are not in it. A large share of Phuket buyers never intend that, and for them the calculation is a different one.
What changes. With no rental income, the entire holding cost (estate charges, utilities, insurance, management, tax) comes out of pocket, and the return you gave up on the purchase capital is no longer offset by anything. Against that, the property is available whenever you want it, in the condition you left it, and it is not being worn by strangers.
How to compare honestly. Take the annual holding cost plus the return you would have earned on the capital elsewhere, and divide by the number of weeks you actually use it. That is the real per-week cost of the holiday home. Then compare it with what renting the equivalent property for those weeks would cost. The comparison is often uncomfortable at four weeks a year and starts to look sensible somewhere past ten.
Where the numbers mislead. Buyers routinely plan for eight weeks and use four, because the flights are long and life intervenes. Use last year’s actual travel, not next year’s intention.
The part that is not arithmetic. A holiday home you own is a different thing from an equivalent rental: no re-choosing every year, your own belongings there, a base rather than a booking. That is a real benefit and it is legitimate to pay for it. It is only a problem when it is presented as an investment case, because as an investment case an unlet second home rarely survives contact with the numbers.
If you want this modelled against your actual visit weeks, real management quotes and your tax nationality rather than generic assumptions, MORE Group runs it with zero buyer commission on buyer-side analysis.
When hybrid strategies work?
There is a middle route that suits more people than either pure option, and it is rarely presented because nobody sells it.
Rent first, buy second. Spend one or two seasons renting in the areas you are considering, in the months you would actually come. It costs $6,000-$13,000 a year, which is real money, and it buys you the single thing no amount of research provides: knowing whether you like Bang Tao more than Kata in February, and whether three months here is what you imagined. Set against a $150,000 commitment and a five-year minimum hold, that is cheap insurance.
Buy smaller than you can afford. A $100,000 unit you use for three months and let for nine, with the balance of your capital invested, hedges both sides of the argument. You hold a real asset and a real position elsewhere, and neither decision has to be right for the plan to work.
Buy for use, let opportunistically. If the property exists so you have somewhere to be, stop optimising the rental. Take a long-term tenant for the months you are away, accept a lower gross, and save yourself the management fee, the turnover wear and the quarterly statements. Owners who try to run a short-stay business around a personal calendar usually get a poor version of both.
The hybrid that does not work is buying a yield asset and then using it heavily. The management agreement, the furnishing standard and the location that make a strong rental unit are not the ones that make a good place to spend a season, and paying an operator 35% to run something you occupy a third of the year is the most expensive version of every option here.
Frequently Asked Questions
It depends on how much you use it and what your capital would otherwise earn. On cash cost alone, with the renter credited an assumed 4% return on the money they did not spend, renting is slightly cheaper up to about three months of annual use and owning is cheaper beyond four. The case for buying rests on appreciation plus net rental income together, not on avoided rent, and it is strongest for buyers spending four months or more a year here.
On cash cost, the crossover sits at roughly three to four months of personal use per year once the renter is credited with a return on their unspent capital. On total return, break-even depends on the property appreciating faster than your alternative investment net of running costs, and both rates are assumed rather than measured: on those assumptions a $150,000 condo at 5% a year beats an 8% invested return over five years, and at 3% it does not beat 6%. Neither number can be promised, which is why the honest answer is a range rather than a date.
Yes, this is standard practice and the basis of the managed rental pool model. Most condo projects in Phuket offer professional rental management where your unit is rented short-term when you're not using it, and you receive net income after management fees. Some contracts allow personal use blackouts during peak season (December-January); check the management agreement terms carefully.
Capital illiquidity (property takes 6-24 months to sell), off-plan developer risk (if buying before completion), market risk (rental demand could soften), and currency risk (THB vs your home currency). These risks are real but manageable: choose established developers in proven tourist zones, hold for 5+ years, and maintain emergency liquidity separate from the property investment.
This is the real comparison, and it cannot be settled with a number on the Phuket side. The total return this answer used to compute (a net yield plus an appreciation rate) is withdrawn: Thailand publishes no letting register and no transaction index for Phuket, so neither component has ever been measured, and adding two unmeasured figures does not produce a measured one. The other side of the comparison is genuinely published: global equity index returns are recorded, reported and auditable over a century. That asymmetry is the finding. An equity portfolio can be shown to have done something; a Phuket condominium's past return cannot be shown at all, which is a risk in itself and one that the phrase 'risk-adjusted' usually obscures rather than captures. What the property adds that a fund does not is personal use, which is real and is not a return.
