We created a solo 401k trust in 2017  (I am a contractor with an LLC).

Inbox me for contact details

Honestly, you need more detailed advice then you'll be able to obtain online.  

@Jason Bradstreet Please provide additional details about the type of property you are seeking.

Also looking to connect with investors who can use my drive, attention to detail, and ability to handle logistics while working under pressure.

Solo 401k plans are no different then full-time employer plans in that they are both sponsored by a business; however, the IRS created solo 401k plans to even the playing between big company employer plans  by relaxing the rules for self-employed businesses to be able to qualify for solo 401k plans (see IRS Pub. 560 which list the requirements to qualify for a self-employed 401k).

Stephen Anderson awesome detailed post, thank you!

Sometimes, there are moments I feel I am still a bit naive, perhaps I should be more aggressive with my sales and rents to maximize a return, but part of me still hold onto the fact that the product we create is what others would call "home".

@Carmen Giamartino need some more details - how much is your house worth?

Always do a math analysis and try to look at the prospective property before you make an offer or at least have a clause in the sales contract that will allow you some time (about 15 days) to do a detailed inspection and possibly back out of the deal without a penalty that will hurt you too much.Do not try to do everything yourself.
