You CANNOT put or transfer any of your assets into SD IRA or Solo 401k.

I was looking to purchase a property, but based on my county's Tax Delinquent Data, the house has been set to a judgement date that recently passed.

Its the local MLS site and they release new data about sales, Days on Market and Sold as % of list price, so you can get an idea of the velocity of the market.

I know a lot of people use excel, but I'd prefer a true database program for better data integrity, scalability, and creating reports.I've searched the forums and looked in the BP files but nothing is coming up in the search (either I'm not searching right, or no one else is dumb enough to want to build their own database).

I've seen some videos online but they seem dated by downloading your data information directly from Facebook or from importing to Yahoo. 

@Gregory A.The following IRS publication is a good source for the ROTH TSP distribution rules. https://www.irs.gov/pub/irs-pdf/p721.pdfHowever, I would first transfer the ROTH TSP to a ROTH IRA since ROTH IRA distributions are not subject to the mandatory 20% withholding at time of the distribution.
