If you are self-employed with no full-time employees you may wish to consider opening a Solo 401k instead of a self-directed IRA as it has several advantages over an IRA LLC such as much higher contribution limits, direct checkbook control (i.e. no need to have the account at a speciality trust company), ability to take a 401k loan, exclusion from unrelated debt finance income tax with respect to investment in real estate acquired with non-recourse financing, etc.Can I contribute to both a Solo 401k and SDIRA?

I special purpose equipment setup. 

Also, any referrals to realtors who specialize in this sort of strategy would be appreciated.

@Allen Masry Congrats that is a heck of a gift! 

We feel this encourages/trains good payment behavior:)We have several MoveIn Specials owners can approve like, free TV, Washer or Dryer (used), etc.Our main goal with MoveIn Specials is to stand out from our competition. - Just lowering the rent really doesn't do that.

My requests for other matters through MFM have gone nowhere and even after requesting a refund and some help with Prime they sent me a video and an email with a special offer to renew for another year.

Seems like there are a lot of individuals in this boat  -  especially in my sons line of work  - which is lighting and tech for special events and music tours.

Specifically:Financing: Do you know of lenders who specialize in unconventional properties like geodomes?

I specialize in working with Canadians that own property down here (I live in Palm Springs, we might be the snowbird capital of the world?).

However if you aren't doing mass scale, we definitely suggest letting the contractor handle material purchasing.As long as the client has all of the materials at the jobsite, place them where they go, they are all the correct type/fit and there are all of the misc parts (adapters/special hardware/etc) needed to do the install.
