Summer subletting saves money for people leaving town and gives short-term renters a cheaper alternative to hotels or corporate housing. Done right, it works out for everyone. Done sloppily, it ends in security deposit fights and eviction notices. Here's how to do it right.
Step One: Get Your Landlord's OK
Before you list anything, read your lease. Most leases either prohibit subletting outright or require written landlord approval. Skipping this step is the single biggest mistake subletters make—if your landlord finds an unauthorized occupant, you can be evicted even if the subletter is perfectly pleasant.
If your lease is silent on the topic, ask anyway. Send a short email or letter stating the dates, the subletter's name, and that you'll remain responsible for the rent and any damages. Get the approval in writing. A text message screenshot beats nothing, but a signed letter is better. Some landlords charge an administrative fee ($50–$150 is common); factor that into your math before you commit.
In Massachusetts, state law gives tenants somewhat broader subletting rights than many other states, but landlord approval is still the safest path. For a solid overview of tenant-landlord basics, see the BostonApartments rental tips page.
Writing a Simple Sublease Agreement
A handshake deal is not a sublease. You need a one-page document that covers at minimum:
- Names: your legal name (sublessor) and the subletter's legal name (sublessee)
- Address and specific room if it's a shared unit
- Exact dates (e.g., June 1 – August 31, 2026)
- Monthly rent and due date
- Security deposit amount and conditions for return
- House rules: guests, noise, cleaning responsibilities, parking
- What happens if either party needs to exit early
Free sublease templates are easy to find online, but read every line before you use one—some are written for a specific state and include clauses that don't apply to you. Both parties should sign two copies and keep one each. If you're subletting just a room rather than the whole apartment, be explicit about which spaces (kitchen, bathroom, laundry) are shared.
Screening a Subletter When You're Not in Town
Summer sublets often involve remote screening because the whole point is that you're leaving. That doesn't mean you skip due diligence—it means you do it over video.
A practical remote screening checklist:
- Video call, not just texts. A 20-minute Zoom or FaceTime call tells you more than a week of messaging.
- Verify identity. Ask them to show a government ID on camera and confirm it matches the name on your sublease.
- Check income or financial stability. One month's rent plus deposit shouldn't exceed 20–25% of their monthly income. Ask for a pay stub, offer letter, or bank statement.
- Contact a previous landlord or roommate. One reference call takes ten minutes and has caught more red flags than any application form.
- Run a background check. Services like Checkr or RentSpree charge $25–$40 and cover credit and criminal history. For a 3-month sublet, this is worth it.
If you want help finding a compatible subletter in the first place, take the compatibility quiz on RoommateAds—it filters for lifestyle and schedule, which matters a lot in a short-term situation.
Handling the Security Deposit
Collect a deposit before handing over keys—no exceptions. One month's rent is standard. Take timestamped photos or a short walkthrough video of every room the day the subletter moves in, and share a copy with them immediately. This is your baseline if something gets damaged.
Keep the deposit in a separate account (many states require this even for sublets) and put the return deadline in the sublease—typically 14–30 days after move-out, depending on your state. Returning it promptly when there's no damage keeps you out of small claims court and keeps your reputation intact if you sublet again next summer.
If Damage Happens
Document everything with photos before the subletter's deposit clears your account. Get repair estimates in writing from a contractor or property manager. You can deduct legitimate repair costs from the deposit, but you need receipts—judges in small claims court dismiss vague damage claims constantly.
Remember: as the primary tenant, you're still on the hook with your landlord. If the damage exceeds the deposit, you'll need to pursue the subletter separately, which is exactly why the signed sublease and identity verification matter.
