I finally fixed the Funda scraper so I should have those ads tomorrow.
The hotsheets for Kamernet are a list of about 500 or more ads published from the last week on Kamernet. Where applicable, the onzelfstandige was applied to the data that the ad contained to give an estimate of the max legal rent price. This can sometimes differ massively from the asking rent price. In these cases, the landlord is likely asking over the limit. Dont avoid these properties like every does: GO FOR THEM.
Once you sign the contract, you can apply to the Huurcommissie to get the rent price reduced by hundreds of euro. This process is relatively simple but takes a few months. In the meantime you pay your rent but if the calculation is correct, you will get anything you over paid back.
Some of the estimates are less than ideal with their accuracy(Row is colored orange): Estimates of apartments with co-signed tenants ARE NOT accurate as these are independent contracts and require a different calculator to work out the rent price. I cannot do this accurately without the house number which kamernet never discloses.
TIPS:
Places belonging to Private owners/real estate agents (Column R) are a more reliable busting fodder as they are unlikely to be using the property themselves. No one should bust a place belonging to their roommate for obvious reasons
Use the filter button in Row 4 to get the results you want
This is a communal shared file so someone else might have used the filter before you. If you see a few results, likely the previous user forgot to reset the filter.
Message every ad, even the ads that are too pricey. Kamernet ads have a very high response rate: 50 - 250 applicants per room. This is a numbers game. Worry about getting a viewing before knowing if the place is 100% bustable.
Kamernet is a paid service. Consider banding together to share an account with someone who isnt looking in the same city as you.
