Is this using a 20% down, conventional or DSCR loan, although I would think a first time investor would use a conventional loan.

Do you know how many times I called and emailed with no response untill I mention I will seek legal help and finally someone replied to me.

* Finally, could you recommend any valuable tools or learning resources?

I’m looking for DSCR loans in the 7s or 8s with no balloon payments.

There are tons of loans out there that use just the projected or actual income from a property vs the payment of the property (DSCR loans). 

Has anyone used bridge loans for this type of strategy or is there any other loans that anyone would recommend other than HELOC?

Finally from a purely from a cash outlay prospective short term, you could rent a house with roommates and your payment would still probably be Lower than house hacking because rates are so high, over the long period 5-10 years obviously it would cheaper ti buy, hope that makes sense 

The real property investment can be repositioned if it proves disappointing in its original form; it can be refinanced or recapitalized if it has too much or too e pensive debt; inflation over time bales out many bad purchases, and finally the investors knowledge, experience and abilities can be leveraged to turn around a cash flow negative property.I’ll provide an exampleThree years ago we purchased a note from a bank secured by two auto repair facilities with a large amount of excess land.  

Finally, the new house was complete, and we could move in.

@Drew Sygit Cool thanks I'll look into DSR loans!
