It sounds like you want more time, so active investing such as flipping or rehabbing might not be ideal.

Unfortunately many lenders will see this as a red flag and may not take the risk to lend you the rest of the money even if you use stated income program or bank statement program but those are for self employed borrowers who have active income from their business but write off to many expenses that when filling their taxes their net income is really low or sometimes negative.

This comes with time and experience but a book that helped me tremendously (not really a sales book, though) was "Boundaries" by Henry Cloud.The most common challenges for RE Agents early relate to generating leads and focusing on income producing activity.I would consider spending 50-75% of your side-hustle time on income generating activities. 

Another thing to keep in mind is to make sure you have an active income to help you have more options in terms of the strategy you will use to begin investing.

Sometimes I question whether there is some real estate investor challenge I am unaware of where investors actively try to one up one another with new ways to toss their money down the drain.

I've been researching this quite a bit and am looking into acquiring an STR that I would actively manage and would keep average stay at 7 days or less.

Hello,I'd like for someone who can assist me regarding the cancellation of my active membership that I paid for 2 weeks ago.

Focus on creating active income and use LTRs to shelter your money. 

Establishing a great relationship with a mentor or group that is actively doing this would be great!
