If it is a breach of contract to do such action, no, it's not true or accurate to say a person "can" do that anymore than it is to say a person "can" rob a bank.

We actually just had several go in on Livingston ave on the west side where I'd not normally think would be desirable, but they look great and really brought the block up.So I'm a huge fan personally from seeing them go up in my own area.  

If it was me personally, I would not.

What if the person staying at your place signed a contract but their 1st payment check bounced.

I personally invest in the North Dallas area (Prosper/Celina) where there is lots of growth in homes with nice lots.

If a person has to ask, at all, I STRONGLY advise to use a PM service for tenant placement. 

As a neighbor, personally I don't care if someone smoke a little weed every now and then, but if they are smoking non stop 25 times a day, you might lose a good tenant over that. 

When you say "we," are you speaking about your business or your personal tax returns, or does your business flow into your personal returns because you file as a sole proprietor?  

In your experience what are some ways I can understand the intent of the person who said they're interested in buying? 

I was wondering if there are any recommend in-person meetups in the LA area.
