My plan is to be financially independent by the age of 30. 

You would have to qualify and close personally, then transfer title to your entity.There are a few non financial institution outlets offering a 30 yr fixed on SFR.

Based on what I owe I could stand to make at least $200k if I sale but could rent it for 3x my mortgage or take out a HELOC and invest that way (?).

My (relatively) short term goal is to be financially independent by 35.

My number one goal for 2018 was creating a financial plan for my fiancee and I to support our early retirement goals, and that led me to real estate. 

I visit and analyze the property, and estimate rehab costs (with experienced inspectors and contractors), add a buffer for unexpected repairs, and provide a financial model with an ROI comparison of a traditional rental vs. short-term rental.Any guidance/tips (positive comments only please) would be greatly appreciated!

I have been heavily educating myself and have now started down my road to Financial Freedom.

Investing while renting is actually the best approach financially.

Standing out can be as simple as doing a great job for current clients and incentivizing them to refer you business, either by a temporary discount, rebate or something similar.

I got my mortgage through Shaneka Pedersen at Elements Financial.
