I suggest that you set clear goals and determine the types of properties you wish to pursue.

Also, any specific platforms or networks you suggest for connecting with them? 

I am looking forward to your insights and suggestions! 

Then based on @Michael Baum's suggestion, I think I will have my cleaner and/or maintenance person do monthly/quarterly maintenance like using using enzyme based cleaners, grease fighting drain treatments and hot water flushing. 

The only item I would suggest is double check the payment terms of the your HELOC... in particular, can you pay interest only or are you required to pay a portion of principle each month on the amount utilized.

Use the two years to learn the area and I would suggest as soon as you can, find a duplex and start a house hack. 

Sub2 is a risky strategy for a long term buy and hold as the longer the deal structure stays in place, the higher the chance that issues will arise (like issues with the loan servicer, insurance, seller filing for bankruptcy, seller dying, seller realizing their DTI ratio and ability to buy their next property is negatively effected and becoming upset about it like in your case, due on sale clause being called, etc.).

Currently started renting it for 2300$ per month , need your suggestion things I can do to fix my below situation. 

There are some great suggestions here on down payment, interest rate, servicing, and underwriting the borrower.  

I would prefer to sell the property vacant or the easiest less stressful way as possible, however I was advised that could deter investors buyers interest as the rental income is a one of my strong selling points.I am open and would appreciate any thoughts and/or suggestions from fellow agents or investors alike.Thanks
