I have a 1 year rental lease of a condo I'm renting from a landlord. If I want to stay for another 3-4 months, how does it usually work? Do I need to ask the rental agent for another 3-4 month lease extension or can I just tell the agent I want to stay on and continue on a periodical basis of a month by month basis, on the same rental terms, after my 1 year lease has finished?

it just rolls month by month after the initial 12 months, unless one party wants a new agreement

In which case, legally, you don't have a bona fide lease agreement. I went through this way back when I was involved in a court case, but my lease was not valid, as I just continued after my first 6-month lease to rent for another 5.5 years, month to month.

In the OP's case, make sure you have a TM30 for your lease before it goes month to month, if the landlord agrees.

Why do you not discuss this with your agent or the landlord ?

This is so he can approach either the agent or landlord with a better understanding of what is a typical rental extension scenario here.

Forums are excellent for seeking advice on matters one may not be familiar with.

I would have thought if you have been a good tenant they will happy extend indefinatedly why wouldn't they ?

You need as much advance notice as possible as other people are calling to rent.

Landlord may give priority to a new tenant who wants to sign a 1 year lease.

What does your lease say? That eventuality may already be covered.

They have had enquiries from someone prepared to sign a 12 month or longer lease and put down a deposit. Someone who only paid for another few days is less attractive and might be gone one morning.

Can't believe this even to be a topic lol, how would it work? Well perhaps by calling and messaging your landlord and to just ask if that is okay? Then you pay until that term and then get your deposit back. Not even necessary for a new lease or contract.

So when would you make a new extra contract? 6 months or more perhaps or if it is a very expensive place with high deposit. A lease contract is anyway pretty much worthless as both costs of a civil procedure and the fact it is not registered with the land department, are more than almost every deposit itself is. Your judgement of the landlord by profiling, and the relationship you maintain, matters more.

It's beyond real today with people being that anti-social, that they can't even come up with the above.

4 months possible, at 25% more expensive than actual contract, would be fair

It totally depends on the landlord - there is no "usual".

At my previous apartment, I signed a one year lease. After that first year, they said I could just keep staying on at the same rent as long as I wanted, and give a month's notice when I wanted to leave - no additional contract to sign. At my current place, there is a new formal lease contract every year. Both scenarios are common.

Maybe offer to pay a bit more than what you were paying on a yearly lease.

Because otherwise he may give priority to someone who wants to rent for one year.

Many of my renters would apply their deposit to the last few months. Not kidding this happened 1/3 of the time. Not much you can do about either that wouldn't make the bad situation even worse. As for you, just pay the rent as usual.

And, both should be in writing, in the rental contract.

Since these are two different scenarios, either should be in writing in a new rental contract.

It's not black and white.

If you are going through an agent, they will want to sting the landlord for another month's rent, commission, so another lease.

I've been renting my condos out over the years.

I'm pretty casual, if the lease expires and tenant wants to remain, I just ask him to keep paying monthly, if tenant wants another lease drawn up, I also provide.

I would want something in writing if I owned the condo.... even if only extending prior lease terms. How long needs to be defined, I am not running a hotel or AIr BnB,

The main problem could be how to handle your deposit.

On a 1 year contract, if you tell that you are leaving less than 2 or 3 months before (depending on contract), you can loose your deposit. On a month y month, if your landlord applies the same logic, you can loose it also.

Better ask a new contract, 3 months or 6 months, but the rental price could be higher.

If you don't care about your deposit, you could stay and pay month by month ... but better speak with your landlord before... A written contract is often much better. For example, 1 month deposit only, and pay 3 months in advance...

Rolling month by month after the expiry of your current contract is ok as long as you won't need a valid lease to show proof of address during that time (E.g. doing Extensions, 90 day reports, getting a CoR etc...).

As has been mentioned try not to use your agent as these will expect the landlord to pay 25-100% of 1 months rent, if possible do the deal directly with your landlord & maybe offer to pay a little bit more.

From the owner's side this is normally an easy yes, especially now - three or four extra months over the quiet season beats an empty unit. The one thing that makes an owner hesitate is an extension that ends mid-high-season, because then he has lost the chance to let it for the year. So ask now, not in the last week, offer month to month at the same rate, and get the answer in writing by message. That message is what protects your deposit. A new contract adds nothing.
