Right now treating it as interest but would like to make it active income to do a solo 401k .

I am actively working on a buyer and a personal money lender list. 

Uses the syndication depreciation losses to help offset active incomeI did read your post mentioned above @Michael Plaks which is very informative.

Currently flippers are much more active locally than buy and hold

I was told by contractors that a home may pass an inspection but once someone is living in it and putting daily stress on the house, things will start to malfunction.

Problem is only "RE pros" get to do it.There are 3 income classifications in the US - Active, Portfolio, and PassiveActive income is income derived from your job, or normal trade or business.Portfolio income is derived from bank instruments - stocks, bonds, etc.Passive income is income earned from investments.Active losses can wipe out both passive and portfolio income, but it doesn't work the other way around.Portfolio (capital) losses are limited to $3,000 annually.Passive losses can only be offset by passive gains.Real estate rental income by its nature is deemed passive per IRC Sec 469One way to get around it is to become a pro - spend more than 750 hours or 1/2 your time in real estate.But most folks aren't real estate pros.

I started to change my mindset, and figure out ways to work efficiently and reduce work stress. 

However, several random websites still have my original listing with the $30,000 price as an active listing and my phone number. 

We have worked with Investors and they are never really married to their Realtors unless you happen to connect with somebody looking to do a long-term hold and actively trying to find a good realistic deal. 

Stay in the same housing plan, school district, etc.Don't just look at sold comps, also look for active, contingent, and under contract listings.
