Hi I am looking to get a mortgage in the next few years and have been reading about the 100% mortgages etc which need proof of rental payments. I am looking into rent tracking however I am trying to figure out how they work out if you've paid your rent in full on time. Is it checked through your bank or does the landlord have to show you've paid. The reason I am asking as sometimes if something needs to be done to the house - and there are a couple of things this month and probably next the landlord will tell me to sort it and just deduct the amount from the rent and send the receipt. Obviously if the rent tracker was to see the less amount would it assume I hadn't paid in full and thus affect my credit score? Just trying to work out if it would be worth it or not.
