I know it isn't ideal, but it seems like he's going to use the low rent as an excuse (even though that isn't right).

Excuse my ignorance, but what it AHS?

I miscalculated the payment using thirty year fixed financing.Not making excuses, just to tired.

Unfortunately, getting paid is almost impossible and all you will be doing is spending more $ also called chasing bad money.Mitch makes some good points as well, however, I have been burned more times than not by "trusting" or accepting tenants excuses, etc.

.…  They are trying to be disruptive using it as an excuse.

In April, after many excuses like grandpa passed away etc, she finally said she could not afford the rent anymore because her husband had lost his job for a while.

The SEC 8 tenant has a very valid reason to fear being kicked out by a new buyer, not that this excuses her choice to violate the owners requirement to inspect.  

Can’t even use the excuse of having a full time job bc there are so many who succeed working 40+ hrs/wk.

I've just started searching for a new job, but I don't want that to be an excuse that stops me from getting started in real estate. 

Most of them have money issues or don’t know how to handle money, most of the time the reason that they are showing up late or making excuses is they are shuffling one project fund to the next, meaning they think they could get away with showing up 4 hrs on project 1 then another 5 hrs on project 2, then collect on both.
