Does this strategy utilizing HELOC really work on saving money and paying off mortgages much quicker?  

Easiest thing to do is to utilize your channel manager to create one (most have this feature) or maybe consider houfy.com or craftedstays.co, they are specific for creating direct websites.

On utilities, I bought a foreclosure in NJ and found out it was not attached to Town sewer and I actually had to extend the main line up to my property then put the lateral in and abandon an old cesspool.  

Then utilize the same designs.

And THEN, the same $1 fee is required when doing a transfer to pay me their utility bills, so then I discounted those by $1 too.

But the answer for everyone may differ.Here are the personal attributes I see in those able to achieve a higher than market ROI, enough higher to be able to “scale”.1- Knowledge of real estate principles, real estate law and real estate finance2- Minimum 3 -5 years full time, or near full time experience directly related to real estate investing3- Ability to utilize technology for increased efficiency, capacity, and accuracy4- Excellent hired legal counsel and excellent hired marketing help5- Established method(s) of obtaining consistently high QUALITY deal flow6- Ability to manage and choose people who are NOT employees: Attorneys, Appraisers, Mortgage Brokers, Real Estate Brokers, Title Companies, Surveyors, Marketing Specialists, Accountants, Contractors, Consultants, Property Managers7- A VERIFIABLE track record of success8- Ability to identify, analyze, and negotiate a deal that can be “worked” for “enhanced” ROI9- Some type of competitive advantage; for example for me it’s my ability to analyze and identify mortgage loans that are actually less risky than all other lenders believe (on the investing in debt side), and on the real property side it’s my ability to analyze”pull the trigger” with LESS information than other investors need,  combined with the ability to pay cash, or raise significant capital almost instantly as well as being able to obtain loans at the lowest prime customer bank rate with no recourse or personal liability.  

@Shmou N.ShmouYou can collect Rent and all other fees; Utilities, parking, or any other fee needed.We don't currently have a notification of the deposit but I will add it to our develoemt roadmap and you will see it in an update.

Plus the 20%-30% more in gross revenue just goes towards utilities, furniture, etc.

Utilizing empty lot space in this way helps to combat the increasing housing prices and limited supply many markets have been experiencing.

BUT, get a solid quote on utilities.
