You bought a condo at Ideo Mobi Sukhumvit a few years back, maybe lived in it for a while, and now you're ready to put it on the rental market. Or maybe you picked up a unit at The Line Ratchathewi as an investment and it's been sitting empty for two months. Either way, you know that empty condo is costing you money every single day. Common area fees, sinking fund contributions, and the slow wear that happens to a place nobody lives in. Let's fix that. Here's the complete checklist for renting out your Bangkok condo, from getting the unit ready to collecting that first month's rent.

Get the Unit Rent Ready Before You List

This sounds obvious, but you'd be surprised how many landlords in Bangkok list a unit with stained curtains, a broken toilet flush handle, and a fridge that smells like someone left som tam in it for three weeks. Tenants here, especially expats paying 25,000 to 45,000 THB per month, notice these things immediately.

Start with a deep clean. Not the kind you do yourself on a Sunday afternoon. Hire a professional team. A full condo deep clean in Bangkok typically costs 2,500 to 5,000 THB depending on the size of the unit. It's the single best investment you'll make before listing.

Next, walk through the unit like a tenant would. Test every air conditioner, run every faucet, flush every toilet, check every light switch. If your AC hasn't been serviced in a year, get it done. A standard AC cleaning runs about 400 to 600 THB per unit, and Bangkok tenants will test the air conditioning before they test anything else. This city is hot. You know this.

Take a look at the furniture. That sagging sofa from Index Living Mall circa 2014 isn't doing you any favors. You don't need to furnish the place like a boutique hotel, but clean, functional, modern furniture helps you command a higher rent. A one bedroom at Life Asoke Hype near MRT Phetchaburi can swing from 18,000 THB to 25,000 THB per month based almost entirely on the condition of the furnishings and how the listing photos look.

Set the Right Price for Your Neighborhood

Pricing a Bangkok condo rental wrong is the fastest way to waste months. Too high and your listing just sits there. Too low and you're leaving money on the table every single month of the lease.

Do your homework on actual market rates, not what your neighbor says they're getting. A 35 sqm one bedroom near BTS Ekkamai might go for 15,000 to 20,000 THB. That same size unit at a newer project near BTS Ari could fetch 18,000 to 28,000 THB. Location, building age, floor level, view, and furnishing quality all play into it.

Check what similar units in your exact building are renting for right now. Look at listings on major platforms, ask your juristic office if they have rental data, and consider seasonal demand. Bangkok's peak rental season typically runs from January through April when new expat assignments start and international school families are locking in housing.

Handle the Legal and Financial Basics

Thailand has specific rules about renting out condos, and ignoring them can create real headaches. First, you need a proper lease agreement. Get one in both Thai and English if you're renting to a foreigner. A standard lease should cover the rental amount, payment dates, deposit terms (typically two months' rent as security deposit plus one month advance), maintenance responsibilities, and termination clauses.

You're also required to report rental income to the Thai Revenue Department. Rental income is subject to personal income tax, and your tenant will likely withhold 5% of the rent at source if they're a company leaseholder. Keep records of everything. Receipts for repairs, common area fees, agent commissions. These are all deductible expenses.

Don't forget to register your tenant at the local immigration office within 24 hours if they're a foreign national. Your building's juristic office can usually help with this, but ultimately it's your responsibility as the landlord. The fine for not reporting is relatively small, but repeated violations can cause problems.

Find Reliable Tenants Without the Guesswork

The traditional way to find tenants in Bangkok involves listing on multiple platforms, fielding dozens of LINE messages, scheduling viewings around your work day, and hoping the person who shows up is actually serious. It's exhausting.

Consider what kind of tenant you want. A Japanese expat family looking for a two bedroom near BTS Phrom Phong will treat your unit very differently than a group of short term travelers. Long term leases of 12 months or more give you stability and reduce turnover costs. Corporate tenants are often the most reliable because their company guarantees the lease.

Screen carefully. Ask for proof of employment or a work permit. Check references from previous landlords if possible. A good tenant at your Aspire Rama 9 unit will save you far more money over two years than squeezing an extra 2,000 THB per month from someone unreliable.

Plan for Ongoing Management

Renting out your condo doesn't end once the lease is signed. Things break. AC units leak. Water heaters die at 11 PM on a Friday. Having a plan for maintenance requests makes the difference between a tenant who renews and one who leaves after 12 months.

Keep a list of trusted repair contacts. A reliable handyman, an electrician, a plumber who actually answers the phone. For a condo near BTS Chong Nonsi, your building's juristic office might coordinate basic repairs, but anything inside the unit is typically your responsibility. Budget around 5,000 to 10,000 THB per year for minor maintenance on a standard one bedroom unit.

Respond to your tenant quickly. Even if you can't fix the problem immediately, acknowledging the issue within a few hours builds trust. Happy tenants stay longer, and every month you avoid vacancy is pure profit.

Renting out a Bangkok condo successfully comes down to preparation, realistic pricing, and treating it like the business it is. Get the unit looking sharp, price it based on real data, handle the paperwork properly, find good tenants, and stay responsive once they move in.
