Running a Thai household from Riyadh.

The problem is the empty months, not the occupied ones

Families plan the stay in detail and the absence not at all. Yet a house in Thailand spends most of the year empty, in a climate hostile to empty buildings: heat, humidity above eighty per cent for months, monsoon rain, insects, and a growing season that never stops. A villa left properly closed and checked comes back to life in a day. Left alone for seven months it produces mould on the ceilings of closed rooms, a pool that has turned, a garden that has swallowed the path, a seized pump and an air conditioning system that smells. All of it is expensive, and all of it is avoidable for a fraction of the repairs.

The families who get this right treat the Thai house as a small standing operation rather than a holiday booking that lasts all year: somebody responsible, a schedule, a budget, a payment mechanism that does not depend on anyone remembering, and a short report on a fixed date. It needs setting up once, in the first weeks of ownership rather than after the first bad arrival.

Who holds the keys

There are three workable answers and one that is not an answer. In a condominium, the building's juristic person handles the common property and often provides or introduces unit management: this is the lowest effort arrangement available and one of the reasons a Bangkok apartment is easier to own from abroad than a coastal villa. In a managed estate, the estate's own management company will usually offer a villa care package covering pool, garden, routine checks and a call out arrangement. Independently, there are established villa management firms across Phuket, Samui and Hua Hin that do this as their business, with reporting and inspection built in.

The arrangement that is not an answer is a friend, a driver or a caretaker with no scope, no schedule and no reporting. It fails the same way each time: everything appears fine until it does not, nobody is accountable because nobody was told what for, and the family finds a six month old problem on arrival. If a trusted individual holds the role, give them a written scope, a monthly checklist, a spending limit and a reporting date. That is not distrust, and people generally perform better inside it.

Bills, and the quiet risk of disconnection

Utilities in Thailand are billed monthly and disconnected for non payment with less ceremony than Gulf families expect. Electricity, water, internet, the estate or building service charge and any security or pool contract each have their own cycle and their own consequence for lapsing. The service charge matters most in a condominium, because arrears can affect the ability to transact on the unit later. Reconnection is not usually difficult, but it means arriving to no electricity in a house sealed in the heat.

The mechanism that works is a small Thai operating account, funded by periodic transfer from the family's own bank, with direct debits set up for the recurring bills and a manager authorised to pay ad hoc costs up to a stated limit. AGP's banking guide deals with account opening, which for a non resident is more involved than it is at home and is worth doing while the family is physically in the country rather than afterwards. Where an account is impractical, the alternative is a management company that pays on the owner's behalf against a float and accounts for it monthly, which is common practice and perfectly workable provided the accounting is itemised and the float is topped up rather than borrowed against.

The maintenance schedule a tropical house actually needs

The specifics vary by property, but the shape of the schedule does not. What follows is the pattern our clients' houses run on, and it is worth agreeing item by item with whoever holds the contract rather than accepting a single line that says maintenance included.

• Weekly: pool chemistry and cleaning, garden and grounds, a walk through of every room with windows and doors checked, a check for water ingress after heavy rain
• Monthly: air conditioning filters, running of every unit and every pump so that nothing sits idle, testing of the generator if there is one, pest inspection, a photographed report to the owner
• Quarterly: deeper air conditioning service, gutters and drainage before and during the wet months, gate and security systems, water tank and filtration
• Annually: exterior paint and sealant inspection, roof inspection, termite treatment renewal, insurance renewal, review of the management contract itself
• Continuously in the wet season: dehumidification or air movement in closed rooms, which is the single cheapest defence against the mould that ruins soft furnishings and wardrobes

Two points families underestimate. First, an empty house should not be sealed completely: rooms need air moving through them, and units need running, or the building deteriorates faster closed than occupied. Second, the pool is the highest maintenance object on the property by a wide margin and the most expensive to recover once it has gone. Neither is a reason to avoid a villa. They are reasons the service contract should be specific.

Staff at a distance

Where a family retains staff between visits, whether a housekeeper, a gardener or a caretaker, the relationship needs the same clarity as any other. Thai employment obligations are real, apply to domestic arrangements, and are a matter for a licensed Thai adviser rather than for assumption. Many families avoid the question entirely by contracting through a management company that employs the staff itself, which is cleaner and usually cheaper than it looks once obligations are priced properly.

The oversight side is mostly about clarity and dignity, which in our experience travel together. State the hours, state who may enter the house and when, state what may be spent without asking and what may not, state that photography inside the property is not permitted, and provide someone reachable who answers. Pay on time and in full, every month, without the family having to remember. Staff who are treated as part of a properly run operation stay for years, which is worth more than any inspection regime, because the greatest protection an absent owner has is a long serving person who has no reason to leave.

The family office view

For principals whose affairs run through a private office or an EA, the Thai house should produce what every other asset produces: a short, dull, regular report. What our own clients receive is a monthly pack of one page and a photograph set: works carried out, faults and their status, spend against budget with receipts, utilities confirmed, and one line flagging anything requiring a decision. Annually, a longer version covering total cost, renewals and the condition of the fabric.

Set a budget in baht at the start of each year and let the manager work inside it, with a stated limit above which approval is required. Families who insist on approving every small item end up with a manager who defers everything and a house where nothing is fixed until someone in another country replies.

The arrival protocol

The last piece is the one that determines how the season starts. Ten days before the family arrives, the house is opened properly: everything run and tested, deep cleaned, linen laundered, air conditioning serviced rather than merely switched on, the pool brought fully to condition, the garden cut back, the internet tested, the cars started and serviced, and any fault found repaired then rather than reported on the day. Two days before, the fridges and store cupboard are stocked to the family's own list, which should live with the manager and be updated after each visit rather than reconstructed each year.

Done that way, the family walks into a cool house that smells clean, with food in the kitchen and nothing to report. Everything in this article exists to produce that one hour, and the families who tell us their Thai house is more trouble than it is worth are, without exception, the ones who never set up the absence.

Verify service charge status and unit management arrangements with the building's juristic person or the estate's management company, confirm utility account details and payment arrangements directly with the providers, and take advice from a licensed Thai adviser or lawyer on employment obligations before engaging household staff directly. Confirm that any property insurance responds to periods when the property is unoccupied, as many policies restrict cover after a stated number of vacant days.
