To rephrase my question, if I put a house I intend to wholesale under contract for $100k, and find an end buyer who agrees to pay $130k, what prevents said buyer from doing a little digging and contacting seller and waiting out whatever option period me and seller agreed upon and saving $30k? 

I get to know bigger pockets and the real estate investing world last year.From that moment, I have been saving up.

They create the false idea that mailing the pre foreclosure lists will get you tens of deals and that deals are easy to get. 

Her idea at present is going to be to purchase the house herself (using traditional financing - high interest rate) and make the payment affordable for the family's rent to cover by arranging the sale well below market value and putting up a down payment of 30+ % of her own money, resulting in a PITI of ~1500.

That leads me to where I am now and some of the thoughts and ideas on what brings me here to make this post.

You'll still need to do some of your own leg work when vetting tenants, but it's easy enough and will save you the ~10% management fee.

I do have funds saved for investment purposes and equity for a HELOC in my primary.

Of course, with all things, the answers to all these matters will depend on the circumstances.California tends to have more laws on the books and requirements and restrictions that it can be a good idea to form a CA LLC for out of state property so that you as a CA resident are covered, and to try to have your contracts fall under the purview of CA courts.

There is a chance I have to live here for the duration of my lease, which ends August 31st.to help save cash, i'm considering doing a STR on my property for 2-3 months while i have moved my stuff there and live between my new home and my current apartment. 

I drove here and have of course have saved my gas receipts.
