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

These homes are in my personal name right now.  

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.

It started with really buying my own personal home, then selling and making a small profit.

With respect to paying $44k off on your HELOC, I personally think that is totally fine and a great start. 

Personally, I started my investment journey with multifamily properties before moving into single-family homes.

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

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

There is a big difference in how those are handled  HAHA I just saw a post and commented where the person wanted to ask if they should overpay for a home because they can get is seller financing.

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.
