We can do all the math, credit checks, point systems, etc....
There is nothing that predicts that the tenants will be good or bad because of the "human" factor
If the tenant signs a year lease they believe they are more protected when trying to evict. If they are on a month to month then it changes their belief of being protected.
I'm a hard *** landlady and have, in the past, dealt with squatters telling me their rights, squatting while trying to do the eviction process. My viewpoint on rights has changed. My last squatter (3years ago) I started the eviction from non payment and went inside to do an inspection. They completely destroyed my place. I took everything of theirs and put it in storage (I paid their first month) and then I changed the locks. Took a lot of pics too. They threatened me and told them to go pound sand. I got new tenants in right away and the tenants fixed up the place (I gave them discounts) and they've been my great tenants since then. Their credit scores were 513 and 620 and they had one eviction 6 years prior....they are the best tenants I've ever had!
