Your HELOC is a fine alternative to come up with emergency funds if need be.

This is not going to be the most "ideal" scenario that you would prefer, but the alternative would be to go through the lengthy process in housing court which may not guarantee any solution. 

I think selling their house on terms is better than the alternative and my sellers in some cases have told me I saved their life.

There are other loan products out there with a varying degree of rates that could be alternatives, but I'm not an expert in mortgage products so I'd recommend speaking with a lender first. 

This is also why so many landlords are moving toward alternative strategies such as short term rentals, medium term rentals, PadSplit/coliving, sober living (like me), and more. 

I am a recent graduate from Texas A&M university and a few months prior, I was considering getting into Wholesaling.I learned that with Wholesaling, there were so many pitfalls concerning wholesaling, legalities that one needs to deal with when wholesaling properties, so I decided to look at another alternative route instead.One of the areas that caught my attention was being a refferal partner for Real Estate and Private Equity investors.Do you guys know what states such activities are going to be legal or illegal?

This could be an alternative method you use if you have trouble getting a HELOC on your property that a lot of investors who use the BRRRR method use.

You can also pay a trusted person using westeren union etc using credit card and then ask them to  deposit in your bank accounthttps://www.bankrate.com/finance/credit-cards/how-to-send-mo...Lower-cost alternatives for sending money with a credit cardMany issuers are introducing new ways for cardmembers to tap into their credit line to send money to friends and family.

Alternatively you can get a deed of trust through a title company.  

I'm simply offering an alternative viewpoint based on the current market conditions and the heightened competition.It's easy to tell people to put sticky notes on someone's door, but what is the true cost and benefit?
