I have forms, but don't use them anymore. 

Some cities are now giving you money in the form of a loan to help build ADU's, which is great.

If the STR is placed into service at the end of the year, they can use the paper-loss from the STR to 'potentially' offset other forms of income such as wages, interest, dividends, etc.Best of luck

Not fun or enjoyable in any form or fashion.

If you have pre-tax and post tax Roth funds in the existing 401k, you will initiate a rollover into a newly formed Solo 401(k), with some funds dropping into the pre-tax bucket and Roth funds dropping into Roth bucket. 3) 3 benefits that I find many real estate investors are attracted to with the Solo 401(k): 1) Higher Contribution Limits (providing you have enough earned income) 2) Ability to contribute to Roth, without MAGI limits where you have to do a backdoor contribution, like you do a Roth IRA. 3) Exemption from UBIT/UDFI on debt financed real estate deals, this could be directly, or through a syndication type deal. 4) Now, we can proceed with, what about the caveats and qualifications to open and maintain a Solo 401(k): 1) You need to have earned income from the business/sole prop. that is sponsoring the Solo 401(k).

You can fairly collect some form of compensation for being the managing member.

My train of thought too just a new situation for me.
