To summarize:
-I have signed a 9 year lease which started Sep 2011 with two youngsters, aged 25, who claimed they were student. I believe one or both are studying law
-Ran into several issues with them
-Gave a termination notice last month that they need to vacate in 6 months, on or before October 31st,  as I need apartment for my own use now
-they also have right to leave with one month notice
-Once of the occupants, the girl seems to have disappeared and doesn't seem to be living in the rented apartment anymore
- A stranger seems to live that other occupant in teh apartment now.Not sure if ne of teh occupants have sub-let it.

Now,
# they paid May rent 15 days late
# They have not paid provisional charges for the months of May yet.
I happen to be teh syndic of this three apartment building and we are on negative balance with this syndic account
# They used the same ploy of not paying provisional charges for couple of months once they entered the apartment.

I have already sent a registered letter last Saturday that they should pay provisional charges before month-end and should pay rent and charges in time henceforth. Else, I told them I will open a standard requette with Judge de paix.

I am worried they use all resources water, heating, common electricity etc but they don't want to pay or delay in paying, once I gave termination notice

(1) What should I do if they don't pay rent ?
(2) what should I do if they don't pay provisional charges
(3) How long should I wait before taking action?
(4) There is NO money in syndic account and we can't pay. Will it become illegal if we, say shut down water or stop electricity to common area etc?
(5) I am a first time landlord and new to all these stuff. In case of filing a "standard requette" with juge de paix, what is better?-Do it myself or do it through a lawyer?

Didn't way to pay 250 euro per month for three paartments, just to do the accounting.

I belive each parent pays 4000 euro to each kid I suppose.
When they were negotiating the contract, I saw the girl dad asking both what do they plan for dealing with common charges. I saw the boy calling his mom, get her approval, confirmed he will take care of that. I assume his mother agreed to pay this part.

Both of them have a small fancy car each. Rent and provisional charges were not a problem so far yet.Still worried when they would settle the annual adjustment.

Both are 25 years old.

Could somebody give some (IPI certified) reference Syndics

SNP proposes lots of training for people wanting to become syndics.

Being Syndic is not a job that you do without having the right skills, level of education, experience etc...

To become Syndic, you will need:
- an excellent technical background (civil engineering)
- an excellent knowledge of the Belgian laws
- financial skills
etc...

We will charged 825 euro as rent(includes garage) and 85 euro as provisional charges.(not fixed). Somebody can what should be the right rent for the description?

Yes, it is!

But I am extremely surprised that "students" have taken such an apartment in WSP.

For the apartment I am renting out in WSP, I have never had Belgian tenants. Belgian candidates who can spend more than 800€/month, become owners (of course not in WSP).

Also no "students" or unemployed people ...

My tenants have always been wealthy expats working for European HQ of American (or other) companies (like Bank of New York Mellon, Cisco, Toyota etc...)

Never Belgian students! They rent "kots". Unemployed people in WSP can apply to get a social home.

Is the rent paid by their parents? How old are they?

An direct electric heater cost the double than a normal heater with gaz or mazout!!! And if they heated the garage with an electric heater, they must be out of their mind!!!

As Panchito says, it's impossible to find a syndic for such a small building. Even at 150€/month, it is a lot of work and responsibilité for small pay...

And the problem would not be the syndic, but the way the two younsters use the appartment and poison your life.

I wish you can get an arrangement at the conciliation. Good luck to you.

Could somebody give some (IPI certified) reference Syndics in WSP who charge 15 euro per month per apartment?

Generally speaking, it is extremely difficult to find a professional Syndic (IPI certified) who accepts to take a "copropriété" made of less than 20 apartments.

Small "copropriétés" are not enough profitable for professional Syndics...

Did you get those extremely important documents?

The whole building doesn't belong to a single owner. 81% to a single owner and with two apartments and  19% to another one whoew is on the attic.

There is an official act de base done way back in 70s, much to the advantage of a single family I suppose.

Looks like they tried to build a "maison de maitre" and three years later decided to split it, perhaps between siblings?

Could somebody give some (IPI certified) reference Syndics in WSP who charge 15 euro per month per apartment?

And from last year experience, I have total cost for heating to ISTA and they divided it simply based on quotite part returned back with report per apartment/caloriment.

Of course, the whole building belongs to a single owner; so you are not in a "copropriété" having an official "acte de base".
By the way, did you apply to get an official permit to divide your "Maison de Maître" into separate apartments?

Took ovr a professional syndic, as they were charging 250 euro per month

In WSP, common Syndics (IPI certified) ask 15€/month per apartment.
If you rent out with a PIM contract, you can charge back all your Syndic costs to the tenants.

25% (or more) as fixed costs based on the "quotités".
65% (or less) as variable costs based on the private consumptions (ista meters).

Took ovr a professional syndic, as they were charging 250 euro per month
shared between three apartments, just to do the accounting. In a way, monthly syndic cost alone was 83 euro. So, we got of teh rid of teh sysndic.

# And from last year experience, I have total cost for heating to ISTA and they divided it simply based on quotite part returned back with report per apartment/caloriment.

Didn't know the practice on 25%/65%. Will enforce this with ISTA coming year.

With respect to rent, it is a 82 m2 apartment, two bedrooms, one small store room, one balcony, a living plus a cellar of 7 m2 and a garage of 20 m2 witha private access o garage through backgarden from street. In effect, close to 110 m2 altogether.

This 82m2 surface area also includes staircase to firstfloor and II floor.
In efefct living area in the rented apartment could be 72 m2 plus a cellar(7sqm) and a garage.

We will charged 825 euro as rent(includes garage) and 85 euro as provisional charges.(not fixed). Somebody can what should be the right rent for the description?

-private consumption of electricity within the apartment is occupier's cost
-private consumption of gas within apartment is on occupier
-central heating shared on quotite part but will start enforcing 25%/65%
-Water simply based on quotite part for thirty years , as it was single family house, we need to have add another three passage water meters and try to compute consumption from say, 5 water meters. Strangely, WE have one mter from Hydobru and two passage meters split across three apartment that actual consumption per apartment can't be done now.
.
The tenants stayed here since September. Issue started slowly after three months of arrival.

As suggested, will NOT go to police. Will see what they offer in conciliation.
I don't want indemnity. They sooner they leave, the better for me.
And I get back my notice.

I have learnt a lesson.

# No more renting of garage as we share common space & back garden between two garages

# Only one year fixed, See how they behave. have something to hold.

# Put all those conditions which may affect character of the building into the contract (Nots sure if this is the right thing) 

They said they moved froma studio. They have a dog and load of things which would need a bug house. Not sure how they has all these stuff and a personal  gym with at least 4 equipments, (one heavy equipment installed close to PVC sanitary pipe from WC by the tenant  ,   big wooden garden table plus chairs, PingPong table, Table FootBall, Two bicycles, Barbeque etc. I still may need to live with this if they want to bring this all out to back-garden for summer.

Well said Grmphh.. And thanks a lot Panchito!!!!

Is it correct WSP?

Well if this is true, you have been had!!

I do hope for your that they don't maintain their drinks cool by putting the bottles in the lavabo and leaving the taps open all days long...

May we know the amount of the rent and the fixed monthly amount to cover all the service charges?

For how many sqm?

Is it correct WSP?

# With respect to heating, They knew how to exploit the system and how to make ISTA to read a 0 consumption on calrorimetrs by not turning on heaters

In standard "copropriétés" the "acte de base" always forseen that all the costs related to the warming installation (electricity, maintenance of the furnace, reparations, issues fixing etc,...) are distributed as following:

25% (or more) as fixed costs based on the "quotités".
65% (or less) as variable costs based on the private consumptions (ista meters).

This is to avoid that occupants that would never turn on their radiators, would not participate to the costs.
