I had few bad tenants experiences, 3 cases to be specific. I also got many good tenants as well over many years in rental market. Sometime you will bump into bad apples for whatever reasons, luck, chance, possibility, etc.
A lot of my friends told me is good to have foreign tenants(European)... Don't think because the tenant is white means they're good tenant, my 3 cases are all white ppl (not a racist statement) just my real life experiences. 1st case was a white couple from UK, was doing ok in the beginning, but the family problem arise and the wife with the kids shift back to UK and left everything behind including the husband. I called the husband and he said he got some problem with his wife (quite honest) but few days later he also ignore everything and fly back without given me any written notice. It was a mess, TNB was sky-rocket (RM3K+) because he left the lights & air-con running when he left (talking about conserving energy, i think we asian are more conservative). All his furnishing was rented as well with 4 months default on rental. I ended up have to cough out few thousand to off-set the unsettled bills (2 months deposit + utilities also can't cover).
The 2nd & 3rd case was French, I just don't know why French react like this, in fact these 2 tenants are also my first experience with French tenant. 2nd case turn bad after 3 months later, it was because he fall sick after a trip to somewhere for work and he didn't recover as fast as he anticipated. I can understand his situation and I am willing to work out something that both mutually agreed upon. But he didn't respond to it and send an email to explain all his grandfather story and expect me to just take it or leave it. So, I tried to contact his company (who arrange this rental for him) and they couldn't do much because he had breach the contract with his company as well. But luckily enough, i manage to find a replacement in 1 month time.
the 3rd case is like a déjavu, they always started good, but slowly, the payment beginning to late, sometime late by half month, sometime 3rd week of the month. Then nothing (is like death pulse). I email, call, sms, every possible way to reach him, no reply, no nothing. This is the sign of a bad tenants.
When this happen, please take immediate action and don't delay. Send warning letters out asap, give they a short time frame to settle before you terminate TNB, Water, etc. If all else fail then make police report for your own protection because this is consider a missing tenant case. (trust me, he probably left the country by now).
I hope my experience can help some of you to avoid (or if unavoidable) at least you know the sign and act fast to avoid further damages done to your wallet.
