Checklist Before Renting a Kost: 12 Things to Verify

Introduction

A checklist matters because most kost problems don't show up in the listing photos — they show up after you've already paid a deposit and moved in. A few minutes of checking upfront can save you from a noisy room, a surprise utility bill, or a landlord who's hard to reach once something breaks.

Confirm the listing is still active/available — message or WhatsApp the owner first rather than showing up unannounced. Kost listings often stay online after a room is taken.
Ask about full pricing up front: base rent, deposit amount, whether utilities (electricity, water) are included, and any admin or cleaning fees that aren't in the headline price.
Ask about minimum contract length before you visit, so you're not disappointed by a 6- or 12-month minimum after you've already fallen in love with the room.

Check water pressure and whether the water heater actually works — turn on the shower and let it run for a minute rather than taking the owner's word for it.
Count the electrical outlets and check their condition. If you work remotely or use multiple devices, make sure there are enough outlets near the desk/bed area, not just one across the room.
Test the wifi signal on-site: ask for the password and run an actual speed test on your phone or laptop, rather than trusting a listed "fast wifi" claim.
If possible, gauge the noise level at different times of day — a room can seem quiet during an afternoon visit and turn out to be next to a busy road or nightlife strip at night.
Check security basics: door locks, how gate access works (key, code, or someone manning it), and whether there's CCTV covering common areas or parking.
Confirm the parking arrangement for your motorbike or car — ask specifically whether it's secured/covered, not just "parking available."

Get the final pricing and included facilities in writing — a WhatsApp chat confirmation is enough, but don't rely on a verbal agreement alone.
Clarify refund and deposit terms in case you need to leave early — ask directly what happens to your deposit if you break the contract partway through.
Confirm who to contact for maintenance issues once you've moved in (owner directly, a building manager, or a separate maintenance contact), so you're not stuck guessing when something breaks.

Reluctance to do a video call or in-person visit before asking for payment — a legitimate owner should have no problem showing you the actual room.
Pressure to pay a deposit immediately "before it's gone" — this urgency tactic is common in rental scams and shouldn't override your own verification steps.
Photos that don't match what's shown on a live video call — inconsistent room layout, missing furniture, or a different view than advertised is a clear warning sign to walk away.

Is it normal to pay a deposit before viewing in person? It's common for popular kost to ask for a small holding deposit to reserve a room, but you should still be able to see real-time photos or a video call of the actual room first. Never send a full deposit based on listing photos alone without some form of live verification.
What's a reasonable notice period before moving out? Most kost contracts expect at least 30 days' notice before moving out, though this varies by owner and contract length — always confirm the exact notice period in writing when you sign, not after.
